Read First: Safety Information
Understand and follow operating instructions carefully. Use the meter, test leads and all accessories only as specified in this manual; otherwise, the protection provided by the meter can be impaired.

WARNING

To avoid possible electric shock, personal injury or death, follow these guidelines:

Do not use if meter appears damaged. Visually inspect the meter to ensure case and jaws are not cracked.
Inspect and replace test leads if insulation is damaged, metal is exposed, or probes are cracked. Pay particular attention to the insulation surrounding the connectors.
To preserve the safety rating of this product, use only test leads with a minimum rating of CAT III 600V. Do not use improvised connections that could present a safety hazard.
Note that the measurement category and voltage rating of combinations of the meter, the test leads, and the accessories is the lowest of the individual components.
Do not use meter if it operates abnormally as protection may be impaired.
Do not use during electrical storms or in wet weather.
Do not use around explosive gas, dust, vapor or in damp or wet environments.
Do not submerge or expose the meter to water and do not use if the meter has ever been exposed to water or other fluids.
Do not apply more than the rated voltage or amperage.
Remove the test leads from the input jacks before measuring current.
Replace battery as soon as battery indicator appears to avoid false readings.
Remove the test leads from the meter prior to removing battery cover.
Do not use without the battery and battery cover properly installed.
Do not attempt to repair this unit as it has no user-serviceable parts.
Use the proper terminals, functions and range for your measurements.
Never ground yourself when taking electrical measurements.
Connect the black common lead to ground or neutral before applying the red test lead to potential voltage. Disconnect the red test lead from the voltage first.
Keep fingers behind the guard rings of the probe tips.
Hold the clamp behind the tactile barrier.
Voltages exceeding 30VAC or 60VDC pose a shock hazard so use caution.
Remove batteries before storage or if unit will not be used for longer than 1 month.

CAUTION
To protect yourself, think “Safety First”:

Comply with local and national safety codes.
Use appropriate personal protective equipment such as face shields, insulating gloves, insulating boots, and/or insulating mats.
Before each use:
- Perform a continuity test by touching the metal tips of the test leads together to verify the functionality of the battery and test leads.
- Use the 3 Point Safety Method. (1) Verify meter operation by measuring a known voltage. (2) Apply meter to circuit under test. (3) Return to the known live voltage again to ensure proper operation.
Always work with a partner.
Remove the batteries for storage or if the meter will not be used for longer than one month. Battery leakage will compromise the safety of the meter and cause damage to internal components.

OPERATION

Non-contact voltage (NCV)
With the NCV tab on the tip of the clamp close to an AC voltage, press the NCV button.

The NCV LED will light and the beeper will sound. The closer the NCV tab is to AC voltage, the louder the beep. To differentiate between hot and neutral in an outlet,insert the NCV tab into each slot in the outlet. The beeper will be much louder on the hot side of the outlet than the neutral. The test lead can also be used to differentiate between the hot and neutral. Plug the red test lead into the V/Ω input jack on the meter. Press the NCV button and insert the probe tip into each slot of the outlet. The beeper will only beep on the hot side of the outlet.

Auto/Manual Ranging Mode ( )
The meter defaults to autoranging mode when powered on. In this mode, the meter automatically selects the best range to display the measurement. By pressing the Range ( ) button on the meter, the manual range mode will override the autoranging feature of the meter. A ( ) appears in the upper left side of the display.
Continue pressing the Range button until the desired range is obtained. Use this mode to lock in a specific range for repeated measurements. To return to the autoranging mode, either depress the Range button for greater than 1 second or turn the meter off and then back on again.

Data Hold Feature
Press the Hold button on the side of the meter to toggle in and out of the data hold mode. “HOLD” appears in the upper left of the meter display when data hold is active. Use the data hold feature to lock a measurement reading on the display. Press the Hold button again to unlock the display and obtain a real-time reading.

Auto Power Off (APO) Feature
The meter automatically powers itself down after about 10 minutes of no use. Press any button, and the meter will wake up and display the last reading taken before power down. This feature can be overridden by holding the Range ( ) button while turning the function switch from Off to any other position. When APO is defeated, the “APO” will be removed from the display. Turning the meter off will restore the APO default.

Measuring AC Current (Amps):

Measuring Voltage:

Measuring Resistance (Ohms):

Verify the circuit is de-energized to obtain accurate measurements.

Verifying Continuity ( ):

Verify the circuit is de-energized.
The meter will sense the level of resistance and beep if the resistance is less than 25Ω to confirm that continuity is present.

Battery Replacement

Ensure test leads are disconnected from circuit or components.
Remove test leads from input jacks on meter.
Remove the two screws from the battery cap.
Remove the battery cap.
Replace batteries with two “AAA” batteries.
Assemble the battery cap to the meter and re-tighten the screws.

Maintenance:
Switch off and disconnect the meter completely before carrying out any maintenance.
Clean the case with a damp cloth and mild detergent. Do not use abrasives or solvents.
Keep away from liquids and ensure the meter is completely dry before use.
