circuit- breakers, wiring, including cables, bus-bars, junction boxes, switches,
socket-outlets in the fixed installation, and equipment for industrial use
and some other equipment, for example, stationary motors with permanent
connection to the fixed installation.

WARNING: Read before using

• To avoid possible electrical shock or personal injury, follow these

instructions and use the Meter only as specied in this manual.

• Do not use the Meter or test leads if they appear damaged, or if
the Meter is not operating properly. If in doubt, have the Meter
serviced.

• Always use the proper function and range for measurements.

• Before rotating the function range selection switch, disconnect

test probe from circuit under test.

• Verify the Meter’s operation by measuring on a known voltage
source.

• Do not apply more than the rated voltage, as marked on the Meter,
between the test probe or between any test probe and earth ground.

• Use the Meter with caution for voltages above 30 V ac rms, 42 V
ac peak, or 60 Vdc. These voltages pose electrical shock hazards.

• Disconnect circuit power and discharge all high-voltage capacitors

before testing resistance.

• Do not use the Meter around explosive gas or vapor.

• When using the test leads, keep your ngers behind the nger guards.
