the instrument, disconnect all other connections (for example, test leads,
computer interface cables, etc.), discharge all circuits, and verify there are no
hazardous voltages present on any conductors by measurements with a
properly-operating voltage-sensing device before touching any internal parts.
Verify the voltage-sensing device is working properly before and after making
the measurements by testing with known-operating voltage sources and test
for both DC and AC voltages. Do not attempt any service or adjustment unless
another person capable of rendering first aid and resuscitation is present.
Do not insert any object into an instrument's ventilation openings or other
openings.
Hazardous voltages may be present in unexpected locations in circuitry being
tested when a fault condition in the circuit exists.
Fuse replacement
Fuse replacement must be done by qualified service-trained maintenance
personnel who are aware of the instrument's fuse requirements and safe
replacement procedures. Disconnect the instrument from the power line
before replacing fuses. Replace fuses only with new fuses of the fuse types,
voltage ratings, and current ratings specified in this manual or on the back of
the instrument. Failure to do so may damage the instrument, lead to a safety
hazard, or cause a fire. Failure to use the specified fuses will void the
warranty.
Servicing
Do not substitute parts that are not approved by B&K Precision or modify this
instrument. Return the instrument to B&K Precision for service and repair to
