Safety Information

To ensure safe operation and service of the meter, follow these instructions. Failure to observe warnings can result in severe injury or death.

• Avoid working alone so assistance can be rendered.
• To enhance safety, test leads should be disconnected from the instrument when not in use
• Do not use test leads or the clamp meter if they look damaged
• Do not use the clamp meter if the tester is not operating properly or if it is wet.
• Use the clamp meter only as specified in the instruction card or the protection provided by the clamp meter may be impaired.
• Special precautions are necessary when operating in situations where exposed live parts at dangerous voltages may be encountered. Personal protective equipment (not supplied with the instrument) should be used.
• The test leads should be disconnected from the instrument when making a current measurement.
• Use caution with voltages above 30 V AC RMS, or 60 V DC. These voltages pose a shock hazard.
• To avoid false readings that could lead to electric shock and injury, replace the battery as soon as the low battery indicator ( ) appears.

Caution: If the meter is used in the vicinity of equipment that generates electromagnetic interference, the display may become unstable or the measurements may be subject to large errors.

Auto Power Off disables: Press buttons (except the Hold button) then switch the rotary knob to power on the meter.

Do not hold the meter in front of the tactile barrier.

Zero

Using the Relative mode (REL), a stable value can be stored, the instrument zeroed at that point, and then any variation from that value is displayed as a direct measurement relative to the stable value.

1. Make measurements and then press the ZERO button. REL: Meter stores the measured value after pressing the ZERO buttons.
2. REL (flashing): The meter saves the offset value. The present value is displayed.
3. Normal: Press and hold ZERO for > 2 seconds to return to normal operation and cancel the offset value.

Data Hold

Min / Max Hold

2. MAX: Meter is saving the maximum and minimum values. The maximum value is displayed.
3. MIN: Meter is saving the maximum and minimum values. The minimum value is displayed.
4. MAX MIN (flashing): Meter is saving the maximum and minimum values. The present value is displayed.
1. Normal: Press and hold MIN MAX to return to normal operation.

Battery Replacement

Replace battery:  is displayed.
To avoid false readings that could lead to electric shock and injury, replace the battery as soon as the low battery indicator ( ) appears.

Peak Hold

2. PMax: Meter is saving the peak maximum and minimum values. Peak maximum value id displayed.
3. PMin: Meter is saving the peak maximum and minimum values. The Peak minimum value is displayed.
4. CAL: Press and hold the PEAK button for> 3 seconds to calibrate the instrument for accurate measurement.
1. Normal: Press and hold the PEAK button to return to normal operation.

Back Light

Backlight Automatic off after 60 seconds.
