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.

Important Safety Information

Electric shock hazard: Contact with live circuits can result in severe injury or death.

Electric shock hazard:

• Do not use the unit if it is wet or damaged. Failure to observe this warning can result in severe injury or death.

Electric shock hazard:

• Do not apply more than the rated voltage between probe tip and earth ground.

• Do not contact the probe tip. 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 probe from the circuit and shut off the unit. Failure to observe these warnings can result in severe injury or death.

Important Safety Information

• 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, 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.

Operation

1. See Typical Uses for illustrations.

2. Remove the probe tip cover.

3. Test the unit on a known functioning circuit or component.

• If the unit does not function as expected, 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 unit to be tested, using the information provided under Lamp Tests and Other Tests.

Lamp Tests

For all lamp tests, press the probe tip to the glass body or the lamp base. Press and hold the Lamp Test button. Touching the base of the lamp during the test can cause incorrect test results.

Lamp type Tube is defective if …

Fluorescent tube does not illuminate* Low-pressure sodium inner tube does not illuminate** High-pressure sodium illumination in inner tube is not a clean, blue line Neon tube does not illuminate Mercury*** tube does not illuminate evenly Metal halide*** tube does not illuminate evenly

* If lamp illuminates with lamp tester but not when installed in an energized fixture, the

filaments or ballast may be defective. The filaments and ballast may be checked with the continuity function.

** If only half of the lamp illuminates, touch the probe tip to the second pin. If the other half

does not illuminate, the lamp is defective.

*** Intermittent or unstable illumination while in the fixture may indicate a faulty ballast.

Note: The Lamp Test button is not used for these tests.

To test/verify Instructions Indications

Continuity* Touch one end of the circuit or Tone and Continuity/

component with probe tip. Voltage LED Touch the other end with free hand. Touch the contact electrode to

complete the circuit.

Diode (forward bias) Touch the cathode with probe tip. Tone and Continuity/

Touch the anode with free hand. Touch the contact electrode to

complete the circuit.

Diode (reverse bias) Touch the anode with probe tip. No indication. Tone and

Touch the other cathode with free hand. Touch the contact electrode to

complete the circuit.
