YOKOGAWA MY600 - Measurement Procedure

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.
