ND 6442-1 61-744 61-746 Instructions
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 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.
