6 Verification and Calibration
Exit the calibration mode either by logging out of the Admin menu or by sending CAL:STAT OFF.
l
Note that any calibration section that was calibrated but not saved will revert to its previous cal-
ibration constants.

Calibration Interval

One Year Calibration Interval
The instrument should be calibrated on a regular interval determined by the accuracy requirements of
your application. A one-year interval is adequate for most applications. Accuracy specifications are
warranted only if adjustment is made at regular calibration intervals. Published accuracy specifications
are not warranted beyond the one-year calibration interval.
Three Year Calibration Interval
Voltage and current programming and measurement accuracy specifications can be extended to a
three-year period calibration interval by multiplying (or increasing) the one-year calibration accuracy
specifications shown in the verification Test Record Forms by a factor of three.

Calibration Setups

Test Considerations

For optimum performance, all verification and calibration procedures should comply with the
following:
Ambient temperature is stable, within 23 °C ±2°C.
l
Ambient relative humidity is less than 80%.
l
30 minute warm-up period before verification or adjustment.
l
Cables as short as possible, twisted or shielded to reduce noise.
