I Safety Warnings and Precautions must be read and understood before the instrument is used. They must be observed during use. I The circuit under test must be switched off, de-energised, securely isolated and proved dead before test connections are made when carrying out insulation and continuity tests. I Circuit connections and exposed-co ...

F Caution: risk of electric shock G Caution: refer to accompanying notes Displayed on the LCD during an insulation test, warns that a hazardous voltage may exist at the test lead probes also observe voltage discharges to a safe level. On battery cover see section 2.0 notes 10 and 11. At terminals do not exceed rated input volt ...

In continuity mode, if a voltage greater than 25 V exists, testing will be automatically inhibited and voltage measurement will be displayed. SP5 Switched probe The SP5 switch probe allows the user to start a test by pressing the [TEST] button on the probe, instead of on the instrument. This allows for complete hands-free tes ...

performing an insulation resistance test, and ensure all necessary health and safety precautions are observed. Automatic Discharge: Capacitive circuits are automatically discharged when the test button is released following an insulation test. The circuit under test must be completely de-energi ...

30seconds (assigned t1) and at 60 second interval (assigned t2). i.e. after 30seconds and 60seconds. DAR = 60 second value/30 second value During all insulation tests the symbol G will flash indicating that a test voltage is present. (a) Insulation resistance testing-timed procedure. 1. Connect the ...

display indicates the actual test current (e.g. 205 mA. The maximum is defined in setup menu. Note: The test current displayed is the actual test current used during the test, which will depend on the resistance of the circuit under test. Resistance measurements (kΩ Range) 1. Turn the instr ...

5. Save new limit by pressing the Lock [ ] button. Saved changed are effected when the Screen Lock symbol stops flashing and disappears. Battery and fuse replacement Battery condition and replacement The battery condition indicator is displayed at all times that the instrument is switched on, as below: 100%, ...
