Page 5: Safety Features And Precautions
Safety Features and Precautions The tester is manufactured and tested in accordance with the following standards: IEC/EN 61010-1/VDE 0411-1 Safety regulations for electrical measuring, control, regulating and laboratory devices – general requirements DIN VDE 0404-1/-2: Testing and measuring equipment for checking the electric safety of electric devices;... -
Page 6: Applications
Applications The tester is intended for the testing and measurement of repaired or modified electrical devices in accordance with DIN VDE 0701-702. These regulations require the measurement of protective conductor resistance, insulation resistance and equivalent leakage current for repaired or modified electrical devices, as well as testing for the absence of voltage at exposed, conductive parts for data processing systems and office machines. - Page 7 Test Socket The DUT is connected to the test socket for the measurement of protective conductor resis- tance, insulation resistance and equivalent leakage current in accordance with DIN VDE 0701-0702, if the DUT is equipped with a mains plug. Connector Jack/Terminal for DUT Phase Conductors This terminal is wired in parallel to the two short-circuited phase conductor terminals at the test socket (8).

Page 9: Mains Connection
Mains Connection Connecting the Tester ➭ Connect the tester to the 230 V mains with the mains plug (1). If no earthing contact socket is available, or if only a three-phase socket is available, connection of the phase conductors, the neutral conductor and the PE conductor can be accomplished with the help of the adapter socket. -
Page 10: Testing Protective Conductor Potential
Testing Protective Conductor Potential ➭ Bring the contact finger into contact with the contacting surface (4) and, at the same time, with a grounded object (e.g. a water pipe). The PE signal lamp (2) must not light up! Potential between the mains plug protective conductor (1) and the contacting surface (4) is then ... -
Page 11: Connecting The Device Under Test To The Test Instrument
Connecting the Device Under Test to the Test Instrument The DUT must be connected to the test socket (8), or to the jacks or terminals (9 and 10) which are connected in parallel to the test socket for the measurement of protective conductor resistance, insulation resistance and equivalent leakage current. -
Page 12: General Measuring Procedures
General Measuring Procedures Line voltage must lie within the allowable range of 207 to 253 V for all of the following mea- surements. This assures that the accuracy of displayed measured values corresponds with the values specified under “Technical Data” (chapter 7, page 23). Line voltage can be measured by setting the measuring function selector switch to the “U Netz 250 V”... -

Page 16: Measuring Insulation Resistance
Measuring Insulation Resistance This measurement may only be performed if the device under test has successfully completed protec- tive conductor resistance testing. If the DUT is equipped with all-pole electrical switches, e.g. undervoltage releases or relays, this test only covers the supply conductor. The device can- not be switched on without being connected to the mains, consequently, it cannot be sub- jected to an effective insulation test. -
