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.
