Operation
Electric shock hazard:
Do not use the tester to measure voltages in circuits that could be
damaged by the Auto V•Ω mode's low input impedance
(approximately 4 kΩ).
Failure to observe this precaution may result in injury and can damage
the unit.
1. Refer to the Settings Table. Set the selector to the proper setting,
press SELECT (when instructed to do so), and connect the test leads
to the tester.
2. Refer to "Typical Measurements" for specific measurement
instructions.
3. Test the unit on a known functioning circuit or component.
• If the unit does not function as expected on a known functioning
circuit, replace the battery.
• If the unit still does not function as expected, send the unit to
Greenlee for repair. Refer to the instructions under the Warranty.
4. Take the reading from the circuit or component to be tested.
Electric shock hazard:
Contact with live circuits could result in severe
injury or death.
