Safety Information

To avoid electric shock and personal injury:
•
Do not use the Meter if it is damaged. Before you use the Meter, inspect the
case and look for cracks or missing plastic. Pay particular attention to the
insulation surrounding the connectors.
•
Inspect the test leads for damaged insulation or exposed metal. Check for
continuity in the test leads. Replace damaged test leads before you use the
Meter.
•
Do not use the Meter if it operates abnormally. Protection may be impaired.
When in doubt, have the meter serviced.
•
When you service the Meter, use ONLY replacement parts specified in the
manual.
•
Do not operate the Meter around explosive gas, vapor, or dust.
•
Never apply more than rated voltage between any input terminal and
ground.
•
Be sure the test leads and rotary switch are in the correct position for the
desired measurement.
•
Never measure resistance in a circuit when power is applied.
•
Never touch the probe to a voltage source when the test leads are plugged
into the 10 A or 40 mA input terminal.
•
Be careful when working with voltages above 60 V dc or 30 V ac rms. Such
voltages pose a shock hazard.
•
Keep your fingers behind the finger guards on the test probes when making
measurements.
•
Use only a single, 9V battery that is properly installed in the meter case to
power the Meter.
To avoid false readings which could lead to possible electric shock or personal
injury, replace the battery immediately after the battery symbol displays.
