DMM800 Series Performance Verification
This section contains procedures to verify that the DMM830, DMM850, and
DMM870 Digital Multimeters perform as warranted. If an instrument fails any
of these checks, it needs adjustment and or repair.
The performance verification procedures provide a valid confirmation of
instrument electrical characteristics and function under the following conditions:
The multimeter operates in an 18to 28C (64to 82F) ambient
environment with a relative humidity of less than 75%.
The multimeter stabilizes in the stated ambient temperature for one hour.
The multimeter warms up for five minutes.
For AC measurements, allow the multimeter to settle to its final value before
taking the measurement.
The multimeter remains fully assembled and in the holster.
The DMM800 Series performance verification consists of the checks listed in
Table 7.

Test Equipment
The performance verification procedures use external traceable test equipment to
directly check warranted characteristics.
Alternative test equipment must meet or exceed the intended minimum
requirements specified in Table 8. If you substitute equipment, you may need to
modify the procedures.
NOTE . Before beginning the performance verification procedures, warm up the
test equipment according to the manufacturer’s recommendations.
