Operation
Electric shock hazard:
Contact with live circuits could result in severe
injury or death.
1. Refer to the Settings Table. Set the selector to the proper setting.
Start with the highest measurement range.
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 and/or fuse.
• 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. If the
resolution is not satisfactory, remove the meter from the circuit
and change to the next lower range.
