Safety
To ensure the safe operation and service of the meter, follow these instructions closely. Failure to
observe warnings can result in severe injury.
WARNINGS
WARNINGS identify hazardous conditions and actions that could cause BODILY HARM or DEATH.
When handling test leads or probes, keep hands and fingers behind the finger guards at all times.
Remove test leads from the meter before opening the battery compartment or meter housing.
Use the meter only as specified in this User Manual or accompanying Quick Start to avoid compromising
the protections provided by the meter.
Be sure to use the proper terminals, switch positions, and ranges when taking measurements.
Verify the meter’s operation by measuring a known voltage. Have the meter serviced if the meter
responds unusually or if there are questions regarding the meter’s functional integrity.
Do not apply more than the rated voltage, as marked on the meter, between terminals or between any
terminal and earth ground.
Use caution working with voltages above 30 VAC RMS, 42 VAC peak, or 60 VDC. These voltages pose a
shock hazard.
To avoid misleading readings that could lead to electric shock and injury, replace the batteries as soon as
the low battery indicator is displayed.
Disconnect power to the circuit under test and discharge all high-voltage capacitors before testing
resistance, continuity, diodes, or capacitance.
