after making the measurements by testing with known-operating
voltage sources and test for both

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 ensure that safety and performance features are
maintained.
