Measurement Category III (CAT III)
is for measurements performed in the
building installation. Examples are measurements on distribution boards,

socket-outlets in the fixed installation, and equipment for industrial use
and some other equipment, for example, stationary motors with permanent

WARNING: Read before using
• To avoid possible electrical shock or personal injury, follow these
instructions and use the Meter only as specified 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 fingers behind the finger guards.
