use of the instrument. Agilent Technologies assumes no liability for the

customer’s failure to comply with these requirements.

Agilent U1251B/U1252B User’s and Service Guide V

WARNING

• When working above 70V DC, 33 V AC RMS or 46.7 V peak, exercise caution – such

range pose a shock hazard.

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

terminals, or between terminal and earth ground.

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

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

circuit. Always place the meter 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 meter before you open the battery cover.

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

• 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 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 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 use any other AC charger adaptor 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.

• 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.

VI Agilent U1251B/U1252B User’s and Service Guide

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.

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

meter, and follow the correct polarity.

•Disconnect test leads from all the terminals during battery charging.
