4. OPERATING INSTRUCTIONS
4.1. WARNING
1. Do not measure voltages that exceed the earthing level by more than 500V in order to
avoid all risks of electroshocks or damage to the instrument.
2. Make sure the insulation of all test leads, probes and connectors is intact prior to
activating the device.
4.2. DC VOLTAGE MEASUREMENTS
1. Connect the red test lead to the "V
P$MDFNDQGWKHEODFNOHDGWRWKH&20MDFN
2. Place the RANGE switch in the appropriate VDC position. Set the switch to the highest
range and work your way down if the voltage range is unknown beforehand.
3. Connect the test leads to the device or circuit to be measured.
4. Activate the device or circuit to be measured. Both the voltage reading and the polarity
will be displayed.
