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

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.

• Remove the test leads from the circuit prior to removing battery cap.
• 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.

• Never ground yourself when taking electrical measurements.
• Connect the black common lead to ground before applying the red test lead to

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.
