Verification test requirements
Be sure that you perform these verification tests:
Under the proper environmental conditions.
After the specified warmup period.
Using the correct line voltage.
Using the proper test equipment.
Using the specified output signal and reading limits.
Environmental conditions
Conduct the calibration verification procedures in a test environment with:
An ambient temperature of 18 °C to 28 °C.
A relative humidity of less than or equal to 80 percent, unless otherwise noted.
No direct airflow on the input terminals.
Warmup period
Allow the DMM6500 to warm up for at least 30 minutes before conducting the calibration verification
procedures.
If the instrument has been subjected to temperature extremes (more than 5 °C above or below T
cal
),
allow additional time for the internal temperature of the instrument to stabilize. Typically, allow an
additional 30 minutes to stabilize an instrument that is 10 °C outside the specified temperature range.
Also, allow the test equipment to warm up for the time recommended by the manufacturer.
Line power
The DMM6500 requires a line voltage of 100 V to 240 V and a line frequency of 50 Hz, 60 Hz , or
400 Hz. Calibration verification tests should be performed within this range.
The instrument automatically senses the line frequency at power up.
