5.1. COURSE OF MEASUREMENTS

 Start up the instrument by setting the switch to the position corresponding to the measurement to
be made.
The instrument can measure insulation values from 10 k  to 10 T  , depending on the test voltage
selected-from 40 to 5100 V
The screen displays:
 the battery symbol and battery charge
condition,
the test voltage selected,

the voltage, frequency and residual current

on the input terminals,
 the date and time.
 Connect the cables of the + and - terminals to the measurement points..
 Connection diagram for measurement of low insulation values (example of a motor)
To measure high insulation values (> 1 G  ), we recommend using guard terminal "G" to avoid leakage
and capacitive effects or eliminate the infl uence of surface leakage currents. The guard terminal is
connected to a surface where leakage currents may fl ow through dust and humidity, e.g. the insulation
surface of a cable or transformer, between two measurement points.
