Agilent Technologies U1251A manual Wa R N I N G

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

WA R N I N G

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.
