ATTENTION
Toujours débrancher l’alimentation de l’équipement testé
avant de commencer la mesure de l’isolation. Ne pas
faire des mesures sur un circuit sous tension. Sinon, cela
pourrait endommager l’appareil.
Note
• Depending on the DUT, the indicated insulation resistance
may not be stable.
• The instrument may produce sounds during a insulation
resistance measurement, but this is not a malfunction.
• Measurements may take longer when the DUT is a
capacitive load.
• The instrument outputs positive voltage from the EARTH
terminal and negative voltage from the LINE terminal.
• When making a measurement, connect the EARTH
terminal to the ground terminal. Generally, connecting the
positive terminal to ground when measuring the insulation
resistance to ground or measuring the insulation resistance
when one end of the DUT is grounded is more suitable for
detecting insulation failures.
Measurement Procedure
1. Connect the probes as shown in the following figure.
• Insert 98008 into the LINE terminal.
• Insert 98009 into the EARTH terminal.
