Normal Measurement Of Current; Measurement Of Balance Leakage Current - Ideal 61-920 Manual De Instrucciones

7-1 Normal measurement of current

* Press the Function button
* Confirm the displayed unit is " mA", and the " MEM" mark is not displayed at the upper left corner of the
LCD.
* Press the lever to open the transformer jaws and close them over a single conductor.
* The measured current value is then displayed on the LCD. (Earth leakage current that flows through a
ground wire can also be measured by this method.)
7-2 Measurement of Balanced leakage current
* Press the Function button
* Confirm the displayed unit is " mA", and the " MEM" mark is not displayed in the upper left corner of
the LCD.
* Clamp onto all conductors except the earthed wire.
* The measured current value is displayed on the LCD.
