WARNING

• Do not defeat power cord safety ground feature. Plug in to a grounded (earthed)

outlet.

• Do not use multimeter in any manner that is not specified by the manufacturer.

• Double-check the multimeter’s operation by measuring a known voltage.

• For current measurement, turn off circuit power before connecting the

multimeter to the circuit. Always place the multimeter 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.

• Do not measure more than the rated voltage (as marked on the multimeter)

between terminals, or between terminal and earth ground.

• 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 multimeter 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 multimeter 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 multimeter 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, functions, and range for your instruments.

• Do not measure voltage when current measurement is selected.

• Use the multimeter with the cables provided.

• Repair or service that is not covered in this manual should only be performed by

qualified personnels.
