Safety Information

Safety Information (cont.)

WWarning

• When using the probes, keep your fingers behind the finger guards on the probes.

• Connect the common test lead before you connect the live test lead. When you disconnect test leads,

disconnect the live test lead first.

• Remove test leads from the meter before you open the battery door.

• Do not operate the meter with the battery door or portions of the cover removed or loosened.

• To avoid false readings, which could lead to possible electric shock or personal injury, replace the

batteries as soon as the low battery indicator (M) appears.

• Use only type AA batteries, properly installed in the meter case, to power the meter.

• To avoid the potential for fire or electrical shock, do not connect the thermocouples to electrically live

circuits.

Caution

To avoid possible damage to the meter or to the equipment under test, follow these guidelines:

• Disconnect circuit power and discharge all high-voltage capacitors before testing resistance,

continuity, diodes, or capacitance.

• Use the proper terminals, function, and range for your measurements.

• Before measuring current, check the meter’s fuses and turn power OFF to the circuit before connecting

the meter to the circuit.
