Read and understand User’s Guide OM-4300-PQLITE before connecting this instrument. Follow all installation and operating instructions while using this instrument. Connection of this instrument must be performed in compli- ance with the National Electrical Code (ANSI/NFPA 70-2002) of USA and any additional safety requirements applicable to your installation. Installation, operation, and maintenance of this instrument must be performed by qualified personnel only. The National Electrical Code defines a qualified person as “one familiar with the construction and operation of the equipment and the hazards involved.” Do not connect to any voltage greater than 600 Vrms. Do not attempt to measure current in any circuit in which the line to ground voltage exceeds the insulation rating (600 Vrms) of the current probes. Although all connection diagrams provided show current probes, they need not be used if information on current is not needed. When a current probe is plugged in, the 4300 will ask you to identify the probe being used so it may select the correct scale factor. After making certain that power to the circuit to be monitored is turned off, connect the 4300 using one of the diagrams on the following two pages. When connection has been completed and power to the circuit is restored, check the circuit waveforms using SCOPE MODE. If they appear to be normal, verify phasing and polarity by pressing the METER MODE key followed by the NEXT METER key until phasors are displayed. When compared to the typical phasors shown, they should have the same phase sequence and polarity. Amplitudes and V/I phasing will vary. 9 CONNECTION AND VERIFICATION (continued) Single Phase Grounded Connection Diagram Source Load Line Neutral Ground CH A CH B CH C CH D 600V RMS MAX PROBE 600V RMS MAX PROBE 600V RMS MAX PROBE 600V RMS MAX PROBE Channel D Connections Optional A A Typical Single Phase Phasors: 0 0 4300-12 Voltage Current (resistive load) Split Phase Grounded Connection Diagram Source Load Line A Neutral Line B Ground CH A CH B CH C CH D 600V RMS MAX PROBE 600V RMS MAX PROBE 600V RMS MAX PROBE 600V RMS MAX PROBE Channel D Connections Optional B A B A Typical Split Phase Phasors: 180 0 180 0 4300-13 Voltage Current (resistive load) 10 CONNECTION AND VERIFICATION (continued) 3 Phase, 4 Wire Grounded Wye Connection Diagram Load Source Line A Line B Neutral Line C Ground CH A CH B CH C CH D 600V RMS MAX 600V RMS MAX 600V RMS MAX PROBE 600V RMS MAX PROBE PROBE PROBE DRANETZ 4300 Channel D Connections Optional C 120 C 120 Typical Four Wire Y Phasors: A 0 Current A 0 Voltage (resistive load) 4300-14 B 240 B 240 3 Phase, 3 Wire Floating Delta Connection Diagram Line A Line B Line C Source Load CH A CH B CH C CH D 600V RMS MAX 600V RMS MAX 600V RMS MAX PROBE 600V RMS MAX PROBE PROBE PROBE DRANETZ 4300 C 90 C 120 Current (resistive load) A Typical Floating Delta Phasors: Voltage 0 B A 4300-15 210 330 B 240 11 ® SPECIFICATIONS for the 4300 with TASKCard PQLite Voltage 10 to 600 Vrms for channels A, B, C, and D 0.5 to 20 Vrms for channel D low range ±1% of reading ±0.05% FS accuracy (inputs > 10% FS) Voltage transients 50 to 1000 volts peak for channels A, B, C, and D 1 to 30 volts peak for channel D low range ±10% of reading ±1% FS accuracy (inputs > 10% FS) Voltage harmonics Total harmonic distortion Individual harmonic levels, 2nd through 50th ** Current 10 to 200% of current probe FS rating for Ch.

If you don’t see the answer to your question, refer to the User’s Guide, P/N OM-4300-PQLITE or call our technical support experts at 1-800-372-6832 or 732-287-3680. 1. Why doesn’t the 4300 turn on? The internal battery may be discharged. Connect the charger and plug it in. The unit may be operated from the charger or the battery may be charged by leaving the unit turned off. 2. Why doesn’t the 4300 display all connected signals in SCOPE MODE? Check that the voltage leads and current probes are connected and that the circuit being measured is live. Press the SELECT CHAN key to see if all desired inputs are turned on. The phasor diagrams shown in the CON- NECTION & VERIFICATION section should be used to determine if input connections are correct. 3. Why doesn’t the 4300 display all connected signals in METER MODE? The circuit may not be live. All connections may not be correct. Use the phasor diagrams in the CONNECTION & VERIFICATION section to determine if all input con- nections are correct. 4. Why is a negative power value displayed? This is usually caused by a current probe clamped on backwards or a reversed pair of voltage leads. The arrows on the current probes should point toward the load. Compare the phasor diagrams available in METER MODE against the examples in the CONNECTION AND VERIFICATION section of this guide. Phase sequences and polarities should agree. 13 WHEN YOU HAVE A QUESTION (continued) 5. Why doesn’t the 4300 record data? Monitoring could be turned off or memory could be full. To turn monitoring on, press the SETUP key on the SCOPE MODE screen to display the SETUP MENU. Then press the 3 key to toggle monitoring on or off. To check if memory is full, press the VIEW DATA key on the SCOPE MODE screen. Then display the SITE STA- TUS screen by pressing the 5 key. If memory is full and the data is no longer needed, it may be cleared using the MEMORY FUNCTIONS selection on the SETUP MENU. If the 4300 still does not record data, refer to the User’s Guide for information on advanced setup options. 14
