and understood.
Each time before the instrument is operated, make sure that it is connected to protective earth.
Before establish the connection and measurement, check if the device under test is connected
to protective earth as well.

important for the accurate measurement. Regularly cleaning up the connector is strongly
recommended.

and the power indicator on the front panel is on with red light. Push and hold the “STBY”

and holding the same button turns the unit to standby mode. When the unit is turned into
standby or off, the last setting is stored and recalled when it is turned on again.
