This instrument fulfills the requirements of the applicable Euro- pean and national EC guidelines. We confirm this with the CE marking. The relevant declaration of conformity can be obtained from Dranetz-BMI. The multimeter has been manufactured and tested in accor- dance with safety regulations IEC/EN 61010–1:2001/ VDE 0411–1:2002. When used for its intended purpose, safety of the operator, as well as that of the instrument, is assured. Their safety is however not guaranteed, if the instrument is used improperly or handled carelessly. In order to maintain flawless technical safety conditions, and to assure safe use, it is imperative that you read the operating instructions thoroughly and carefully before placing your instru- ment into service, and that you follow all instructions contained therein. Observe the following safety precautions: • The instrument may only be operated by persons who are capable of recognizing contact hazards and taking the appro- priate safety precautions. Contact hazards exist anywhere, where voltages of greater than 30 V may occur (RMS value). • Avoid working alone when taking measurements which involve contact hazards. Be certain that a second person is present. • The maximum allowable voltage between the jacks (8) and earth is 600 V CAT II. Overload capacities are listed in chapter 15. GB • Be prepared for the occurrence of unexpected voltages at devices under test (e.g. defective devices). For example, capacitors may be dangerously charged. • Make certain that the measurement cables are in flawless condition, e.g. no damage to insulation, no interrup- tions in cables or plugs etc. • No measurements may be made with this instrument in elec- trical circuits with corona discharge (high-voltage). • Special care is required when measurements are made in HF electrical circuits. Dangerous pulsating voltages may be present. • Measurements under moist ambient conditions are not per- missible. • Be absolutely certain that the measuring ranges are not over- loaded beyond their allowable capacities. Limit values can be found in the “Measuring Ranges” table in chapter 15 “Characteristic Values”. • The current measuring ranges are protected by an internal 250 mA fusible link. A defective fuse can only be replaced by Dranetz-BMI service personnel. The maximum permissible volt- age for the measuring current circuit is 600 V AC/DC in the “mA” ranges. • The instrument may not be used in power installations. Repair, Parts Replacement and Balancing When the instrument is opened, voltage conducting parts may be exposed. The instrument must be disconnected from the measuring circuit for repair, replacement of parts or balancing. If repair or balancing of a live, open instrument is required, this may only be carried out by trained personnel who are familiar with the dangers involved. DranTech ULTRA User’s Guide 5 Errors and Extraordinary Strains If it may be assumed that the instrument can no longer be oper- ated safely, it must be removed from service and secured against further use. Safe operation can no longer be relied upon • if the instrument demonstrates visible damage, • if the instrument no longer functions, • after a long period of storage under unfavorable conditions. 2 Initial Start-Up Batteries Batteries have already been installed to your instrument, and it is ready for operation. Refer to chapter 16.1, page 24, before placing your instrument into service for the first time, or after it has been in storage! Switching the Instrument On Manually ➭ Press the MENU/ON|OFF key. Activation is acknowledged with a brief acoustic signal. As long as the key remains pressed, all segments of the liquid crystal display (LCD) are active. The LCD is shown on page 3. After the key is released, the instrument is ready for opera- tion. Note! Electrical discharge and high frequency interference can cause incorrect displays, and may block the measuring sequence. To reset, switch the instrument off, and then back on. If this procedure is unsuccess- ful, briefly disconnect the battery from its contact terminals. Switching the Instrument Off Manually ➭ Press and hold the MENU/ON|OFF key, until the display is deactivated. Deactivation of the instrument is acknowledged by two brief acoustic signals. Automatic Shut-Off – As battery saving circuit: Your instrument shuts itself off automatically, if the measure- ment value remains constant for a long period of time (max. fluctuation < ±400 digits, 1° C or 1° F per minute), and if none of the keys or the rotary switch are activated for a period of 10 minutes. Deactivation of the instrument is acknowledged by a brief acoustic signal. Exceptions are as follows: Transmit or memory mode, and continuous operation. – If battery voltage drops below the required level: The battery symbol ( ) appears approximately 10 minutes before the instrument is shut down. Connect the NA5/600 mains power pack and save data to a PC before replacing the batteries. Disabling Automatic Shut-Off The instrument can also be switched to “CONTINUOUS ON”. ➭ Simultaneously press the ON/MENU/OFF key and the yellow multifunction key when switching the instrument on. The “CONTINUOUS ON” function is indicated at the LCD with the symbol. 6 DranTech ULTRA User’s Guide 3 Selecting Measuring Functions and Ranges 3.1 Automatic Measuring Range Selection The multimeter is equipped with automatic measuring range selec- tion. This automatic feature is active as soon as the instrument is switched on, and automatically selects the measuring range which provides optimum resolution. The voltage measuring range selected in the V AC selector switch position remains active after switching to frequency measurement “Hz”, and automatic measuring range selection is disabled. We thus recommend the selection of a suitable voltage measuring range in the V AC selector switch position before switching to fre- quency measurement. The instrument selects the measuring range automatically for the following measured quantities: Switching to the Switching to the Next Reso- Measured Quantity Next Highest Range Lowest Range lution at ±(... d + 1 d) at ±(... d –1 d) V , Ω, Hz 6½ 1100000 100000 V , mA 5½ — 100000 3.2 Manual Measuring Range Selection (Quick Measurements) Measurements performed using a suitable fixed measuring range are executed more quickly than those which utilize automatic range selection. Automatic range selection can be deactivated, and ranges can be manually selected according to the following table. The manual mode is deactivated by pressing and holding the GB MAN|AUTO key (approx. 1 s), by activating the rotary switch or by switching the instrument off and back on again. Acknowledge ⇓ MAN/ Function Dis- Acoust.

The selected unit of measure and the type of current are displayed as well. A minus sign appears in front of the numeric value for the measurement of zero-fre- quency quantities, if the positive pole of the measured quantity has been connected to the “–V” input. If the measuring range upper limit of 1,250,000 is exceeded for measured quantities V and mA, “0L” is displayed (overload). The digital display is refreshed every 0.5 to 2 s (see “Display Update” on page 21). DranTech ULTRA User’s Guide 7 5 Minimum and Maximum Value Storage “MIN/MAX” with Time Stamp Minimum and maximum measurement values can be stored to memory with the MIN/MAX function. The most important appli- cation for this function is the determination of minimum and maxi- mum values during long-term observation of measurement values. It can be activated for all measuring functions. ➭ Apply the measured quantity to the instrument. ➭ Select the measuring range with MAN|AUTO. ➭ Activate the MIN/MAX function. ➭ Repeated activation of the AVE/MIN|MAX key causes switch- ing amongst: MAX > t > MIN > t > MAX ... The measuring ranges can only be selected manually when the “MIN/MAX” function is active. The “MIN/MAX” function is deactivated, and stored MIN and MAX values are deleted by pressing and holding the MIN/MAX key (approx. 1 s), by activating the rotary switch or by switching the instrument off and back on again. 6 Voltage Measurement ➭ Depending upon the voltage to be measured, set the rotary switch to V or V . ➭ Connect the measurement cables as shown. The “V” jack should be grounded. Note! In the 600 V range, an intermittent acoustic signal sounds alarm if the display value exceeds 600 V. ! Attention! Make absolutely certain that none of the current ranges are active when the multimeter is connected for voltage measurements! If the breaking limit values for the elec- tronic fuse are exceeded due to operator error, both the operator and the instrument are in danger! Simulta- neous connection to both current and voltage measuring circuits is prohibited! –V + VAC VDC ~ + ⊥/ – /⊥ 8 DranTech ULTRA User’s Guide blac k re d 6.1 Zero Balancing (for V , mA , Ω and °C) ➭ Select the desired measuring range with the MAN|AUTO key. ➭ 2-Wire Resistance Measurement, Current Measurement or Temperature Measurement with Pt100 or Pt1000: short-circuit the positive and negative poles of sockets “mAΩ2” or “°C2”, respectively. Voltage Measurement, Temperature Measurement with Thermocouple or 4-Wire Resistance Measurement: short-circuit the positive and negative poles of sockets “V/°CTC” or “ΩSense”, respectively. ➭ Briefly press the MAN|AUTO and AVE/MIN|MAX keys simultaneously. The instrument acknowledges zero balancing with an acoustic signal and “000.0000” (±1 digit, decimal place depends upon mea- suring range) and the “ZERO” symbol appear at the LCD. The previously displayed measurement value serves as a reference value (max. ±30000 digits). ➭ Zero balancing can be deleted: – by pressing the MAN|AUTO key after which deletion is acknowledged with an acoustic signal, – by selecting a different measuring function – or by switching the instrument off. Note The zero balancing values (offset) for temperature measurement are stored to memory in the resistance and/or voltage measurement ranges and serve as reference values.

After this selection has been made with the rotary switch, the DC current mode is always active. ➭ Select the current type, either “DC” or “AC+DC”, which corre- sponds to the measured quantity by briefly pressing the multi- function key. Double check for correct current type at the LCD. ➭ Securely connect the instrument to the load component in series as shown (without matching resistor). Zero Balancing, see chapter 6.1, page 9 –mA + – (+) / ~ max. 600 V ! + (–) / ~ L Current Measurement Tips: • The instrument may not be used in power installations. • The measuring circuit must be mechanically stable and protected against unintentional interruption. Conductor cross sections and connection points must be substantial enough to avoid excessive overheating. • In the 100 mA measuring range, an intermittent acoustic signal warns you if the measurement value has exceeded the measuring range upper limit value. • The current ranges are protected by an internal 250 mA fusible link. A defective fuse can only be replaced by Dranetz-BMI ser- vice personnel. The maximum permissible voltage for the measuring current cir- cuit is 600 V AC/DC in the “mA” ranges. 10 DranTech ULTRA User’s Guide R x Curre nt Pa th 8 Resistance Measurement Resistance measurements can be performed for devices with high inductive or capacitive components such as motors, transformers, coils etc. ➭ Be certain that the device under test is voltage-free. Extraneous voltages distort measurement results! ➭ Set the rotary switch to “Ω2” (2-wire measurement connection) for the measurement of resistance values greater than 1 kΩ, or to “Ω4” (4-wire measurement connection) for resistance values within a range of 100 Ω to 1 kΩ. ➭ Connect the device under test as shown. 2-Wire Connection for Rx ≥ 1 kΩ 4-Wire Connection for Rx ≤ 1 kΩ –Ω2 + –Ω4 + –Ω2 + Rx GB Zero Balancing for the “Ω2” and “Ω4” Functions Cable and transition resistance can be eliminated with zero balanc- ing for measurements of small resistance values. Zero Balancing, see chapter 6.1, page 9 8.1 Continuity Testing for Resistance Measurement ➭ Set the selector switch to the position. ➭ Connect the DUT to the “Ω2” sockets as required for 2-wire resistance measurement. The continuity test functions within a measuring range of 0 to 100 Ω, and a continuous acoustic signal is generated for values ranging from 0 to 10 Ω. Note! “0.L” is displayed if the DUT is not connected. 9 Frequency Measurement ➭ Set the selector switch to the V position. ➭ Select the most favorable measuring range. ➭ Now set the selector switch to the Hz position. The selected volt- age measuring range remains active. ➭ Apply the measured quantity in the same way as for voltage measurement. Measurable frequencies and allowable voltages can be found in chapter 15, page 18.

All other parameter changes are lost, and the default settings are once again active when the instrument is switched back on. 13 Data Transmission via RS232 Interface The multimeter is equipped with an infrared interface for the trans- mission of measurement data to a PC. Measurement values are optically transmitted via infrared light through the housing to an interface adapter (accessory), which is plugged into the multimeter. The RS232 interface at the adapter allows for connection to a PC via an interface cable. Furthermore, commands and parameters can be uploaded from the PC to the multimeter. 16 DranTech ULTRA User’s Guide For example: • Select and read out measuring parameters • Select measuring function and range • Start measurement • Read out measurement values (online readout with simultaneous measurement: shortest possible sampling period is 100 ms) The interface is always active if the instrument is switched on. 13.1 Selecting Interface Parameters Addr – Address If several multimeters, interfaces or memory adapters are connected to the PC, each device requires its own address. Address number 1 should be assigned to the first device, 2 to the second device etc. rS232 – Baud Rate / Transmission Mode The baud rate can be selected, and operation in the transmission mode can be simultaneously activated with the rS232 command. Transmission can be interrupted with the MENU/ON|OFF key: rAtE rS232 ↵ 9600 19200 ↵ . 14 Accessories BD232 Interface adapter (without memory) allows for remote control of the multimeter, as well as the transmission of mea- surement data from up to six multimeters to the PC. DranWin®10 Software DranWin®10 software is used to process and display measurement GB data at a PC. Sampling can be triggered manually with an adjust- able sampling interval, or in a signal dependent fashion. Storage of data in ASCII format can be controlled with two trigger thresholds per measuring channel, as well as by means of system time. The following prerequisites must be fulfilled for the implementa- tion of DranWin®10: Software Requirements: – MS WINDOWS 95, 98, ME, NT, 2000 or XP. Hardware Requirements: – a WINDOWS and IBM compatible PC with at least a Pentium CPU and 32 MB RAM – a VGA monitor – a hard disc with at least 20 MB available memory – a 3.5” floppy disc drive for 1.4 MB floppy discs – a MICROSOFT compatible mouse – if you want to print your data: a WINDOWS compatible printer.

Attention! Disconnect the instrument from the measuring circuit before opening to replace batteries! 16.1 Batteries Note! Battery Replacement Stored measurement values are deleted when the bat- tery is replaced. We recommend connecting the power pack, or uploading data to a PC with the help of Dran- Win®10 software, before replacing batteries in order to prevent data loss. Operating parameters remain in memory. Before initial start-up, or after storage of your instrument, make sure that no leakage has occurred at the instrument battery. Repeat this inspection at regular intervals. If battery leakage has occurred, electrolyte from the battery must be carefully and completely removed with a damp cloth, and a new battery must be installed. If the “ ” symbol appears at the LCD , you should replace the bat- teries as soon as possible. You can continue to take measurements, but reduced measuring accuracy may result. The instrument works with two 1.5 V batteries per IEC R6 or IEC LR6, or with corresponding, rechargeable NiCd batteries. Battery Replacement ➭ Lay the instrument onto a flat surface with the front panel facing down, loosen the two screws at the back and lift out the housing base starting at point (a). ➭ Remove the batteries from the battery compartment. ➭ Insert two 1.5 V mignon cells into the battery compartment in the direction indicated by the polarity symbols. ➭ Important for reassembly: First set the housing base onto the housing top and align accurately (see photo below). Then press the two housing halves together, first at the bottom front (a), and then at the top front (b). (b) (a) ➭ Retighten the housing base with the two screws. ➭ Please dispose of depleted batteries properly! 24 DranTech ULTRA User’s Guide 16.2 Power Pack Use only the N5/600 power pack for power supply to your instru- ment. The highly insulated cable assures safety for the operator, and the power pack provides for reliable electrical isolation. When a mains power pack is used, the batteries inside the instrument are disconnected automatically. Country Type Article No. Germany NA5/600 Z218F Note! We recommend that zero balancing be performed in accordance with chapter 6.1, page 9, if the power pack is used. 16.3 Housing No special maintenance is required for the housing. Keep outside surfaces clean. Use a slightly dampened cloth for cleaning. Avoid the use of cleansers, abrasives or solvents. 17 Multimeter Display Messages Message Function Significance FAIL RAM test RAM test failed * Good RAM test RAM test successfully completed all operating modes battery voltage has dropped to below 2.3 V FULL transmission mode measurement value memory is full OL measuring indicates overload GB * A hardware problem may have occurred.
