General Safety Information

WARNING

• When working above 30 VAC RMS or 60 VDC, exercise caution – such range

poses a shock hazard.

• Do not measure more than the rated current and voltage (as marked on the

clamp meter).

• Ensure the test leads are disconnected from the input terminals when

measuring current with the clamp meter. Keep your fingers behind the hand

guard when performing measurements.

• When connecting probes, always connect the common test probe first. When

disconnecting probes, always disconnect the live test probe first.

• Detach test probes from the clamp meter before you open the battery cover.

• Do not use the clamp meter with the battery cover or part of the cover removed

or loose.

• Replace the battery as soon as the low battery indicator is shown on the

annunciator display. This is to avoid false readings, which may lead to possible

electric shock or personal injury.

• When measuring temperature, keep the thermocouple probe as close to the

meter as possible, and avoid contact with surface above 30 VAC RMS or 60 VDC

as this will pose shock hazard.

• Do not operate the product in an explosive atmosphere or in the presence of

flammable gases or fumes.

• Inspect the case for cracks or missing plastic. Pay extra attention to the

insulation surrounding the connectors. Do not use the clamp meter if it is

damaged.

• Inspect the test probes for damaged insulation or exposed metal, and check for

continuity. Do not use the test probe if it is damaged.

• Do not service or perform adjustments alone. Under certain condition,

hazardous voltages may exist, even with the equipment switched off. To avoid

dangerous electric shock, service personnel must not attempt internal service

or adjustment unless another person, capable of rendering resuscitation or first

aid, is present.

User’s and Service Guide V

Use the clamp meter only as specified in this guide. Otherwise, the protection provided by

the clamp meter may be impaired.

WARNING

• Do not substitute parts or modify equipment to avoid the danger of introducing

additional hazards. Return the product to the nearest Agilent Technologies

Sales and Service office for service and repair to ensure the safety features are

maintained.

• Do not operate damaged equipment as the safety protection features built into

this product may have been impaired, either through physical damage,

excessive moisture, or any other reason. Remove power and do not use the

product until safe operation can be verified by service-trained personnel. If

necessary, return the product to the nearest Agilent Technologies Sales and

Service office for service and repair to ensure the safety features are

maintained.

CAUTION

•Turn off circuit power and discharge all high-voltage capacitors in the circuit

before you perform resistance and capacitance measurements or continuity and

diode tests.

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

•Never measure voltage when current measurement is selected.

•Use only the recommended battery type. Ensure proper insertion of battery in the

clamp meter, and follow the correct polarity.
