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.
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 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 set the
unit to any function except Ω.
Failure to observe these warnings could result in severe injury or death.
•
•
Electric shock hazard:
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 electromagnetic interfer-
ence can result in unstable or inaccurate readings.
Failure to observe these warnings could result in severe injury or death.
•
•
•
Electric shock hazard:
The fuse is 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.

Important Safety Information
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.
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.

Operation
Electric shock hazard:
Contact with live circuits could result in severe injury
or death.
For highest accuracy:
Lay the meter flat on a non-metallic surface, away from any magnetic
objects.
Read the scale straight on—not at an angle.
If possible, select a range that results in a reading in the upper 1/3 of the
scale.
1. Zero the meter as follows: Remove the test leads from the circuit or
component. Do not allow the tips of the test leads to touch each other. With
the Selector in any position, adjust the Mechanical Adjustment Screw to
set the pointer to the far left side of the scale.
2. Before taking a resistance measurement, set the meter to Rx1K. Connect
the tips of the test leads together and read the meter. Use the Ohm
Adjustment Knob to set the needle to the far right side of the scale
(0 ohms).
Note: If you cannot zero the meter, replace the battery. If you cannot zero
the meter after replacing the battery, send the unit to Greenlee for repair.
3. Refer to the Settings Table. Start with the highest measurement setting of
the measurement function.
4. 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.

5. Take the reading from the circuit or component to be tested. If the resolu-
tion is not satisfactory, remove the meter from the circuit and change to
the next lower range. When measuring resistance, adjust the 0Ω ADJ.
potentiometer after changing ranges. Refer to step 2.
Note: If the pointer moves below the far left side of the scale, this may
indicate that the polarity is reversed and the meter is reading a negative
value. Reverse the leads and read the meter again.
