Safety Considerations
Read the information below before using this instrument.
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 for design, manufacture, and intended
use of the instrument. Agilent Technologies assumes no liability for the
customer’s failure to comply with these requirements.
CAUTION
• Disconnect circuit power and discharge all high-voltage capacitors
before testing resistance, continuity, diodes, or capacitance.
• Use the proper terminals, function, and range for your
measurements.
• This device is for use at altitudes of up to 2,000 m.
• Never measure voltage when current measurement is selected.
• Always use the specified battery type. The power for the meter is
supplied with four standard AAA 1.5 V batteries. Observe the
correct polarity markings before you insert the batteries to ensure
proper insertion of the batteries in the meter.
WARNING
• Do not exceed any of the measurement limits defined in the
specifications to avoid instrument damage and the risk of electric
shock.
• Do not use the meter if it is damaged. Before you use the meter,
inspect the case. Look for cracks or missing plastic. Pay
particular attention to the insulation surrounding the connectors.
• Inspect the test leads for damaged insulation or exposed metal.
Check the test leads for continuity. Replace damaged test leads
before you use the meter.
• Do not operate the meter around explosive gas, vapor, or wet
environments.
