OPERATING INSTRUCTIONS

Turn unit on

Press and hold the power button for ½ second, then release. Listen for single-beep sound and watch for a steady green LED to illuminate in the tip of the tester. The tester is now activated and is operational. Test on known live circuit to verify tester functionality. See Silent Mode for additional power-on options.

Turn unit off

Press and hold the power button for ½ second. Listen for a double-beep sound and watch the "power on" green LED turn off. The tester is now deactivated and is not operational. The "power on" green LED visually confirms battery sufficiency, system integrity, and operation/active mode. Always test on known live circuit to verify tester functionality prior to and after each use.

System self-test

The "power on" green LED visually confirms battery sufficiency, system integrity, and operation/active mode. Always test on known live circuit to verify tester functionality prior to and after each use.

Checking for the presence of AC voltage

Prior to and after each use, test on known live circuit to verify tester functionality. Place tip of the tester near an AC voltage. If the tester detects voltage, the "power on" LED in the tip of the tester changes color from green to red and a continual beeping sound is generated.

Voltage Range 50 TO 1000 VOLTS AC
Audible High-pitched continuous beeping sound
Visual Green LED Turns OFF and Red LED illuminates continuously

Low battery indication

Scenario 1 – Powering on the tester: The "power on" LED in the tip of the tester changes from a steady green to a blinking green and a series of beeping sounds is generated. The tester then turns off. The unit is now deactivated and is not operational; the batteries require replacement. To replace the tester batteries refer to the Maintenance section titled "Battery Replacement."

Scenario 2 – Operating the tester: If the LED lights dim and the tone fades, the tester may require new batteries. To replace the tester batteries refer to the Maintenance section titled "Battery Replacement."

Auto power off

After 4 minutes of non-use, the tester automatically powers off to conserve battery life. Listen for a double-beep sound and watch the "power on" green LED turn off. The tester is now deactivated and is not operational.

Silent mode

The tester can be operated with only visual indication of voltage. With the tester powered off, press and hold the power button for 2 seconds.

MAINTENANCE

Battery replacement

  • Orient the tool/tester with the pocket-clip facing you.
  • Gently depress the tab, Fig. 2, until you can slide the end-cap off the main body of the tester.
    MAINTENANCE - Battery replacement - Step 1
    Fig.2
  • Remove the batteries using caution to prevent damage or injury to the internal components.
  • Replace with two AAA 1.5 volt or IEC LR03 or NEDA 24A batteries.
  • Place batteries into tester with the positive terminals facing the tip, Fig. 3.
    MAINTENANCE - Battery replacement - Step 2
  • Carefully align and slide the end-cap onto the body of the tester, Fig. 4. Push the cap until it is fully seated (denoted by a clicking sound), Fig. 4.
    MAINTENANCE - Battery replacement - Step 3
    Fig.4
    • Align locking tab with cap.
    • Hold pocket-clip on cap close to tester body while sliding cap onto tester.
  • warning Note: Hold pocket-clip on cap close to tester body while sliding cap onto tester.
  • Test on known live circuit to verify tester functionality.

Cleaning tester

  • Tester contains sensitive electronic components; do not submerse in liquid.
  • Do not use alcohol, ammonia or cleaners containing solvents to clean tester.
  • Gently wipe the tester with Klein Kleaners® (CAT. # 51425), a damp cloth or a cloth containing a mild cleaning solution.
  • Make sure the tester is completely dry prior to operation.

WARNINGS

  • It is important that users of this tester read, understand, and follow all warnings, cautions, safety information, and instructions in this manual before operating or servicing this tester. Failure to follow instructions could result in death or serious injury.
  • Risk of electric shock and burn. Contact with live circuits could result in death or serious injury.
  • Use caution with voltages above 30V AC as a shock hazard may exist.
  • A blinking or steady red glow and an audible beep indicate voltage present. If no indication, voltage could still be present.
  • Before and after each use, verify operation by testing a known working circuit that is within the rating of this unit.
  • Never assume neutral or ground wires are de-energized.
  • The tester WILL NOT detect voltage if:
    • the wire is shielded.
    • the operator is not grounded or is otherwise isolated from an effective earth ground.
    • the voltage is DC.
  • The tester MAY NOT detect voltage if:
    • the user is not holding the tester.
    • the user is insulated from the tester with a glove or other materials.
    • the wire is partially buried or in a grounded metal conduit.
    • the tester is at a distance from the voltage source.
    • the field created by the voltage source is being blocked, dampened, or otherwise interfered with.
    • the frequency of the voltage is not a perfect sine wave between 50 and 500Hz.
    • the tester is outside of operation conditions (listed in Specifications section).
  • Operation may be affected by differences in socket design and insulation thickness and type.
  • In bright light conditions, the LED visual indicators will be less visible.
  • Do not use if green LED is not illuminated.
  • Do not use if tester appears damaged or if the tester is not operating properly. If in doubt, replace the tester.
  • Do not apply more than the rated voltage as marked on the tester (1000 volts AC).
  • Detection above 50V is specified under "normal" conditions as specified below.
    The tester may detect at a different threshold at different conditions, or may not detect at all unless:
    • The tip of the tester is within 0.25" of an AC voltage source radiating unimpeded.
    • The user is holding the body of the tester with his or her bare hand.
    • The user is standing on or connected to earth ground.
    • The air humidity is nominal (50% relative humidity).
    • The tester is held still.
  • Always wear approved eye protection.
  • Comply with local and national safety requirements.
  • If this product is used in a manner not specified by the manufacturer, protection provided by the product may be affected.
