2 Read First

Understand and follow operating instructions carefully. Use the meter only as specified in this manual; otherwise, the protection provided by the meter may be impaired.

 WARNING

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

․ Do not use if meter appears damaged, Visually inspect the meter to ensure case is not cracked and back case is securely in place. ․ Inspect and replace leads if insulation is damaged,metal is exposed or probes are cracked. Pay particular attention to the

insulation surrounding the connectors. ․ Do not use Meter if it operates abnormally as protection maybe impaired. ․ Do not use during electrical storms or in wet weather. ․ Do not use around explosive gas, dust or vapor. ․ Do not apply more than the rated voltage to the meter. ․ Do not use without the battery and the back case properly installed.

2 Safety Information

2

․ Remove the test leads from the circuit prior to removing battery cap. ․ Do not attempt to repair this unit as it has no userserviceable parts. ․ Voltages exceeding 30VAC or 60VDC pose a shock hazard so use caution.

CAUTION

To protect yourself, think “Safety First”: ․ Use appropriate personal protective equipment such as safety glasses, face shields, insulating gloves, insulating boots and/or insulating mats. ․ Before each use.

- Perform a continuity test by touching the test leads together to verify the functionally 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. ․ 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.

․ Always work with a partner. ․ When using the probes, keep fingers as far

behind the probe tips as possible. ․ Never connect a source of voltage with the function rotary switch in Ω/ :</ A //Hz

position.Never set the meter in  A function to measure the voltage of a power supply circuit in equipment that could result in damage to the meter and the equipment under test.

Non-Contact Voltage (NCV)

NCV

1. NCV switch will be activated on any function or at OFF status.

2. Test leads are not used for the NCV test.

3. Press the NCV button. The display goes black, a tone sounds and the red LED lights up to verify the instrument is operational. The NCV button must be held down to detect the presence of voltage without use of the leads.
