Read First: 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 guidelines:
• 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.
• Replace battery as soon as battery indicator appears to avoid false readings.
• Remove the test leads from the circuit prior to removing battery cover.
• Do not attempt to repair this unit as it has no user-serviceable parts.
CAUTION
To protect yourself, think "Safety First":
• Voltages exceeding 30VAC or 60VDC pose a shock hazard so use caution.
• 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
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.
• 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.
• Always work with a partner.
• When using the probes, keep fingers as far behind the probe tips as possible.
