U1241B/U1242B User's and Service Guide
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.
• Observe all markings on the instrument before connecting any
wiring to the instrument.
• When working above 60 VDC, 30 VAC RMS or 42 V peak, exercise
caution – such range pose a shock hazard.
• Do not measure more than the rated voltage (as marked on the
multimeter) between terminals, or between terminal and earth
ground.
• 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.
• Detach test probes from the multimeter before you open the battery
cover.
• Do not use the multimeter with the battery cover or part of the cover
removed or loose.
• Replace the battery as soon as the low battery indicator
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 multimeter
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.
