Measurement Of The Pi - Chauvin Arnoux C.A 6505 Notice De Fonctionnement

Press the START/STOP key to start the
measurement.

START/STOP
During measurements the instrument will beep every 10 seconds to alert the user that a high voltage
is present.
Press the START/STOP key again to stop the measurement. The instrument continues to measure
external voltages but the test result remains displayed on the main display unit.
To ensure your safety, the instrument will automatically discharge the circuit under test, allow for the
voltage displayed to fall back below 25 V before disconnecting the leads.
