Page 2: Safety Warnings
Safety warnings Safety Warnings and Precautions must be read and understood before the instrument is used. They must be observed during use. 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. -
Page 3: Symbols Used On The Instrument
Symbols used on the instrument: Caution: risk of electric shock 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. -
Page 4: Lcd Display
LCD Display Auxiliary digital display Continuity indicator Battery Lock indicator condition indicator Warning-refer to user guide TRMS indicator Out of range indicator Lead null indicator Audible alarm indicator Figure 3 LCD display In continuity mode, if a voltage greater than 25 V exists, testing will be automatically inhibited and voltage measurement will be displayed. -
Page 5: Standard Insulation Resistance Testing
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-energised and securely isolated before test connections are made. - Page 6 DAR is the ratio between the insulation resistance values at 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 will flash indicating that a test voltage is present.
