Errors and Extraordinary Strains If it may be assumed that the instrument can no longer be operated safely, it must be removed from serviced and secured against unintentional use. Send the instrument to the Repair and Replacement Parts Service Department; see Chapter 10, page 13.
2 Applications The METRISO PRIME insulation tester complies with regulation IEC 61557/EN 61557/VDE 0413 “Measuring and Monitoring Equipment for the Testing of Electrical Safety in Systems with Nominal Voltages of up to AC 1000 V and DC 1500 V” Part 2, insulation resistance testers. It is suited for the measurement of insulation resistance for devices and systems in a voltage-free condition with nominal voltages of up to 1000 V.
3.4 Analog Display Logarithmic representation of the upper resistance scale allows for quick recognition of the magnitude involved. In order to achieve the required accuracy for testing of protective measures, the RANGE key allows for switching to the expanded lower limit measuring range of 100 k ... 100 M. The orange colored LEDs, (4) and (5), at the right end of the scale indicate which of the two resistance measuring ranges is currently active.
! Attention! Contact Hazard Do not touch the conductive ends of the test prods when the instrument has been activated for the measurement of insulation resistance. This may cause current to flow over your body, which, although it does not reach life endangering levels, causes a clearly discernible shock. When measurements are made at capacitive devices under test, e.g. cables, the DUT may be charged with voltages of up to approximately 5000 V, depending upon selected nominal voltage.
5.3 Measurements with the Guard Cable (with Accessory Guard 5000A) The measurement of very high impedance resistances presupposes extremely small measurement currents, and can be rendered problematic by influences such as electromagnetic fields, moisture or surface currents. For this reason, the measurement set-up must be implemented in an accurate fashion. For measurements within a range of 100 G (10 G) ...

7 Maintenance ! Attention! Before replacing batteries completely disconnect the device from all external power circuits. For purposes of transport and maintenance we recommend that the range selector switch be set to the OFF/V position, in order to prevent unintentional activation of the tester. 7.1 Batteries The condition of the batteries should be checked from time to time. Discharged or corroded batteries must be removed from the battery compartment.
7.4 Recalibration, Repair, Parts Replacement, and Device Balancing Voltage conducting parts may be exposed when the instrument is opened. The instrument must be disconnected from the measuring circuit before repair, replacement of parts or balancing. If the repair of an open, live instrument cannot be avoided, this may only be performed by trained personnel who are familiar with the dangers involved.
Ð Turn the crank in the direction indicated by the arrow at a speed which causes the signal LED at the upper right hand portion of the display to light up and burn continuously. Note If the signal LED is not lit, or if it flickers, test voltage is too low, i.e. too little power is being delivered by the crank generator. Measurement values are only valid if the signal LED is continuously lit.
