Important Safety Information
Electric shock hazard:
Contact with live circuits could result in severe
injury or death.
Electric shock and fire hazard:
•Do not expose this unit to rain or moisture.
•Do not use the unit if it is wet or damaged.
•Use test leads or accessories that are appropriate for the
application. Refer to category and voltage rating of the test lead
or accessory.
•Inspect the test leads or accessory before use. They must be
clean and dry, and the insulation must be in good condition.
•Use this unit for the manufacturer’s intended purpose only, as
described in this manual. Any other use can impair the
protection provided by the unit.
Failure to observe these warnings could result in severe injury or
death.
Electric shock hazard:
•Do not apply more than the rated voltage between any two input
terminals, or between any input terminal and earth ground.
• Do not contact the test lead tips or any uninsulated portion of the
accessory.
Failure to observe these warnings could result in severe injury or
death.

Important Safety Information
Electric shock hazard:
•Do not operate with the case open.
• Before opening the case, remove the test leads from the circuit
and shut off the unit.
Failure to observe these warnings could result in severe injury or
death.
Electric shock hazard:
The fuses are an integral part of the overvoltage protection. When
fuse replacement is necessary, refer to “Specifications” for the
correct type, size and capacity. Using any other type of fuse will
void the overvoltage protection rating of the unit.
Failure to observe this warning could result in severe injury or
death.
Electric shock hazard:
•Unless measuring voltage, current or frequency, shut off and
lock out power. Make sure that all capacitors are discharged.
Voltage must not be present.
•Using this unit near equipment that generates electromagnetic
interference can result in unstable or inaccurate readings.
Failure to observe these warnings could result in severe injury or
death.

6
Important Safety Information
Set the selector and connect the test leads so that they correspond
to the intended measurement. Incorrect settings or connections
can result in a blown fuse.
Electric shock hazard:
•Do not attempt to repair this unit. It contains no user-serviceable
parts.
•Do not expose the unit to extremes in temperature or high
humidity. Refer to “Specifications.”
Failure to observe these precautions may result in injury and can
damage the unit.
Electric shock hazard:
Do not change the measurement function while the test leads are
connected to a component or circuit.
Failure to observe this precaution may result in injury and can
damage the unit.

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
and connect the test leads to the meter. 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 fuses.
• 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.
