General Safety Information
The following general safety precautions must be observed during all
phases of operation, service, and repair of this instrument. Failure to
comply with these precautions or with specific warnings elsewhere in this
manual violates safety standards of design, manufacture, and intended
use of the instrument. Agilent Technologies assumes no liability for the
customer’s failure to comply with these requirements.
WARNING
• When working above DC 60 V, AC 30 Vrms or AC 42.4 Vpeak, exercise caution
– these ranges pose a shock hazard.
• Do not measure more than the rated voltage (as marked on the instrument)
between terminals, or between terminal and earth ground.
• Double-check the instrument operation by measuring a known voltage.
• This instrument is designed for measurement under CAT II 150 V. Avoid
measuring power mains with voltage exceeding 150 V.
• For current measurement, turn off circuit power before connecting the
instrument to the circuit. Always place the instrument in series with the
circuit.
• 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 instrument before you open the battery cover.
• Do not use the instrument with the battery cover or part of the cover removed
or loose.
• Recharge or replace the battery as soon as the low battery indicator
flashes on screen. This is to avoid false readings, which may lead to possible
electric shock or personal injury.
• Do not use the instrument if it is damaged. Before you use the instrument,
inspect the casing. Look for cracks or missing plastic. Do not operate the
instrument around explosive gas, vapor, or dust.
• 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 use any other AC charger adapter apart from the one certified by
Agilent with this product.
• Do not use repaired fuses or short-circuited fuse-holders. For continued
protection against fire, replace the line fuses only with fuses of the same
voltage and current rating and recommended type.
• 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.

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.
• Do not measure voltage when current measurement is selected.
• Use only the recommended rechargeable battery. Ensure proper
insertion of battery in the instrument, and follow the correct polarity.
• Disconnect test leads from all the terminals during battery charging.
