• Inspect the Clamp meter, test leads and accessories before every use. Do

not use any damaged part.

• Never ground yourself when taking measurements. Do not touch exposed

circuit elements or test probe tips.

• Do not operate the instrument in an explosive atmosphere.

• To reduce the risk of fire or electric shock, do not expose this product to

rain or moisture.

• The meter is intended only for indoor use. To avoid electrical shock hazard,

observe the proper safety precautions when working with voltages above

60 VDC, 42.4 Vpk, or 30 VAC rms. These voltage levels pose a potential

shock hazard to the user.

• Before and after hazardous voltage measurements, test the voltage

function on a known source such as line voltage to determine proper

meter functioning.

• Keep your hands/fingers behind the hand/finger barriers (of the meter and

the test leads) that indicate the limits of safe access of the hand-held part

during measurement.

• Inspect test leads, connectors, and probes for damaged insulation or

exposed metal before using the instrument. If any defects are found,

replace them immediately.

• This Clamp-on meter is designed to apply around or remove from un-

insulated hazardous live conductors. Individual protective equipment must

be used if hazardous live parts of the installation could be accessible.

• Exercise extreme caution when: measuring voltage >20 V // current >10

mA // AC power line with inductive loads // AC power line during electrical

storms // current, when the fuse blows in a circuit with open circuit voltage

>600 V // servicing CRT equipment.

• Remove test leads before opening the case to change the battery.

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

testing resistance, continuity, diodes, or capacitance.

• To avoid false readings, which could lead to possible electric shock or

personal injury, replace the batteries as soon as the low battery indicator

(  ) appears.

• To avoid electric shock hazard, do not use the HOLD mode to determine if

a circuit is live. Unstable readings will not be captured and displayed.

CAUTION

For non-invasive ACA current measurements, clamp the jaws around only

one single conductor of a circuit for load current measurement. More than 1

conductor will cause false readings
