Make sure that the device under test does not make contact with any equipment or persons during testing. U = 115 V / 230 V L– N Liability Exclusion In the event of sparkover, PCs operated in proximity to the test instrument may “crash” resulting in data loss. All data and programs should be suitably backed L1 up before high-voltage testing is performed, and computers should be shut N down if necessary. A crash may occur even if no RS 232 connection has been established. PE green-yellow The manufacturer of the test instrument assumes no liability for direct or L1 consequential damage to computers, peripherals or data which occurs during high-voltage testing.

Limit values for each of the respective standards can be queried and changed if required with the setup menu (selector switch in the Auto position), but changes can only be made which result in even stricter testing than is required by the respective standard. Newly entered limit values become effective immediately. However, these are only stored to memory permanently after activating the store function in the setup menu. If the limit values set forth in the standards for certain safety classes need to be restored despite individualized settings, the menu function all values per standard in the limit values sub-menu must be selected and acknowledged with the key. If the limit values set forth in the standards are changed, the instrument’s device software can be updated via the RS 232 interface.

Devices assigned to all of the following safety classes are equipped with basic If the device under test is connected via the jacks instead of the test socket, insulation, and provide for protection against electrical shock by means of other limit values are used because higher power consumption is possible in various additional precautions as well. this case (e.g. part 1 has an equivalent leakage current limit value of 1 mA per kW). See table entitled “Maximum Allowable Limit Values for Equivalent Leakage Safety Class I Devices Current in mA” on page 21. Exposed, conductive parts are connected to the protective conductor so that they are not charged with voltage if the basic insulation should fail. 5.2 Application Parts (electrical medical devices) Safety Class II Devices Type B Application Parts (body) These devices are equipped with double insulation or reinforced insulation. Devices of this type are suitable for both internal and external patient applications, except for use in direct proximity to the heart. These devices provide for adequate protection against shock especially as Safety Class III Devices regards: These devices are powered with safety extra-low voltage (SELV). Beyond this, no voltages are generated which exceed SELV. These devices may not be con- • Reliable leakage current nected to the mains.

Devices of the following safety classes are allowable: Note: The DUT may only be connected to jacks 1 to 3 at the test instrument. It I, II, III or devices with internal electrical power supply. is only possible to perform a visual inspection, a measurement of the insulation resistance or the supply voltage, see parameter “SC III UV” on page 34. Type BF Application Parts (body float) Classification Parameter (in the Sequence ... menu) Same as type B, but with type F insulated application parts. The test instrument always performs testing in accordance with the strictest limit values of the respectively selected safety class. The test is failed if this limit value is exceeded. Type CF Application Parts (cardiac float) However, higher limit values are allowed for certain devices under test. Devices of this type are suitable for use directly at the heart. The application part may not be grounded. If the classification parameter has been activated (= x), the user is asked if higher limit values are allowable for these devices. If the user responds with Devices of the following safety classes are allowable: “Yes”, the DUT is reevaluated and the test may be passed. I, II or devices with internal electrical power supply.

During measurement, the connector cable must only be moved in as far as it is accessible during repair, modification or testing.
