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. They 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.
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.
•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.

6
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 unit.
•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.
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.

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 electromagnetic 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.

1. Set the selector according to the Settings Table and connect the test leads to the unit.
Start with the highest measurement range.

Set to match transistor type.
* Continuous tone indicates circuit resistance is less than approximately 80 Ω.
** A “1”in the left-most column indicates that the diode is reverse biased.
*** Insert the legs of the transistor (emitter, base and collector) so that they correspond to
the terminals (E, B and C).
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. If the resolution is not satisfactory, remove
the leads from the circuit and change to the next lower range.
Electric shock hazard:
Contact with live circuits can result in severe injury or death.
