severity of the hazard. The message after the signal word provides information for
preventing or avoiding the hazard.
SAFETY ALERT SYMBOL
Immediate hazards which, if not avoided, WILL result in severe injury or death.
Hazards which, if not avoided, COULD result in severe injury or death.
Hazards or unsafe practices which, if not avoided, MAY result in injury or property
damage.
Read and understand this material before operating or servicing
this equipment. Failure to understand how to safely operate this
tool can result in an accident causing serious injury or death.
Electric shock hazard:
Contact with live circuits can result in severe injury or death.

Important Safety Information
Electric shock hazard:
• Do not use the unit if it is wet or damaged.
• Use test leads or accessories that are appropriate for the application. See the
category and voltage rating of the test lead or accessory.
• Inspect the test leads or accessory before use. The item(s) must be clean and dry,
and the insulation must be in good condition.
Failure to observe these warnings can result in severe injury or death.
• Do not operate with the case open.
• Before opening the case, remove the test leads (or jaw) from the circuit and shut off
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 while the test leads are connected to a
component or circuit.
Failure to observe this precaution can result in injury and can damage the instrument.
• 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.
Unless measuring voltage, current, power, power factor 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.

Using the Features
• HOLD Press momentarily to hold the present value on the display and store it in the
memory. Press again to exit this mode.
•Mode Button (Unlabeled) Press momentarily to toggle between AC, DC and frequency
when measuring current and volts.
•MIN MAX AVG PEAK Holds the minimum or maximum value on the display. Press once to
hold the minimum value; press again to hold the maximum value; press again to hold the
average value (press again to hold peak value, if measuring an AC signal). Press and hold to
exit this mode.
•∆REL Finds the difference between two measurements. While taking a measurement,
press ∆to set the display to zero. The ∆icon will appear on the display. Take the second
measurement. The value on the display will be the difference between the two measure-
ments. Press and hold to exit this mode.
•RECORD Press momentarily to begin recording the input. RECORD will appear on the
display. The CMPL-100 will record up to 1600 events; when the memory is full, RECORD
will flash on the display. To save the recorded data in the memory, exit the RECORD mode
before turning the meter off. Use the CMPL-100-1A PC interface kit (purchased separately)
to retrieve the data from the memory.
To clear the memory, turn off the unit. Then press and hold the RECORD button while
turning the unit on. Release the RECORD button after “CLEP” appears on the display.

Operation
Electric shock hazard:
Contact with live circuits can result in severe injury or death.
1. Set the selector according to the Settings Table and connect the test leads to the unit.
Start with the highest measurement range.
2. See Typical Measurements for illustrations of typical uses.
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.
4. Take the reading from the circuit to be tested.

Notes:
• Clamp the jaw around one
conductor only.
• Close the jaw completely.
• Center the wire in the jaw for
highest accuracy.
Note: DC Current flowing
through the jaw in the
direction indicated by the
arrow produces a positive
reading. (AC current always
reads positive.)

Notes:
• The + sign on the jaw must face the power source.
• COM connection (black lead) should remain connected to the same phase during both
measurements.
• A positive (+) PF indicates an inductive load. A negative (–) PF indicates a capacitive load.
Power factor value is correct for balanced loads only.
• Both power measurements may be positive, or one may be negative. Make sure all
connections are correct to obtain proper measurements.
