Warning
To avoid possible electric shock, personal injury, or death, read the following before using
the Meter:
•
Use the Meter only as specified in this manual, or the protection provided by the Meter
might be impaired.
•
Do not use the Meter in wet environments.
•
Inspect the Meter before using it. Do not use the Meter if it appears damaged.
•
Inspect the test leads before use. Do not use them if insulation is damaged or metal is
exposed. Check the test leads for continuity. Replace damaged test leads before using
the Meter.
•
Verify the Meter's operation by measuring a known voltage before and after using it. Do
not use the Meter if it operates abnormally. Protection may be impaired. If in doubt, have
the Meter serviced.
•
Whenever it is likely that safety protection has been impaired, make the Meter inoperative
and secure it against any unintended operation.
•
Have the Meter serviced only by qualified service personnel.
•
Do not apply more than the rated voltage, as marked on the Meter, between the terminals
or between any terminal and earth ground.
•
Always use the power cord and connector appropriate for the voltage and outlet of the
country or location in which you are working.
•
Remove test leads from the Meter before opening the case.
•
Never remove the cover or open the case of the Meter without first removing it from the
main power source.
•
Never operate the Meter with the cover removed or the case open.
•
Use caution when working with voltages above 30 V ac rms, 42 V ac peak, or 42 V dc.
These voltages pose a shock hazard.
•
Use only the replacement fuse(s) specified by the manual.
•
Use the proper terminals, function, and range for your measurements.
•
Do not operate the Meter around explosive gas, vapor, or dust.
•
When using probes, keep your fingers behind the finger guards.
•
When making electrical connections, connect the common test lead before connecting
the live test lead; when disconnecting, disconnect the live test lead before disconnecting
the common test lead.
•
Disconnect circuit power and discharge all high-voltage capacitors before testing
resistance, continuity, diodes, or capacitance.
•
Before measuring current, check the Meter's fuses and turn OFF power to the circuit
before connecting the Meter to the circuit.
•
When servicing the Meter, use only specified replacement parts.
