Important Safety Information
Electric shock hazard:
Contact with live circuits can 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.
• Inspect the test leads 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 can 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 can result in severe injury or
death.

Important Safety Information
Do not change the measurement function or range while the
test leads are connected to a component or circuit.
Failure to observe this precaution can result in injury and can
damage the unit.
The fuse is an integral part of the overvoltage protection.
When fuse replacement is necessary, see 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 can result in severe injury or
death.
• 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 can result in severe injury or
death.

Important Safety Information
• Unless measuring voltage or current, shut off and lock out
power. Make sure that all capacitors are discharged. Voltage
must not be present.
• 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.
• Using this unit near equipment that generates electromag-
netic interference can result in unstable or inaccurate
readings.
• 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. See Specifications.
Failure to observe these precautions can result in injury and
can damage the unit.

Using the Features
Power and measurement range selector: Slide the selector up to
turn unit on. Line the selector up with desired settings. Always
start with highest setting. Slide the selector down to turn unit off.
Function selector: Slide the selector side to side to set the proper
position prior to connecting the test probes. Disconnect the
probes from the circuit or component before switching to a new
function.
Test leads: Red probe polarity is positive. Remove test lead caps
to perform tests.

Operation
Electric shock hazard:
Contact with live circuits can result in
severe injury or death.
1. See the Settings Table. Set the measurement range selector to
the proper setting, starting with the highest measurement
setting. Never apply more than 300 V to the unit.
2. See 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. See the address shown under
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.
