WARNING
• 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 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
conditions, 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.
• Do not substitute parts or modify equipment to avoid the danger of
introducing additional hazards. Return the product to 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
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, continuity, diodes, or
capacitance tests.
• Use the correct terminals, function, and range for your measurements.
• Never measure voltage when current measurement is selected.
• Ensure proper insertion of battery in the multimeter, and follow the
correct polarity.
