2 Safety Information
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.
3
․ 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.

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.
