Calibration Recommendation
The pre-calibration guidelines are shown as follows:
-
Calibration should only be performed by a qualified personnel.
-
The environment should be 23 °C ± 5 °C, and the relative humidity < 80% (RH).
The test equipment requirements listed in Table 1 or equivalents are required to perform the calibration and
performance verification test procedures. Alternative equipment may be used as long as the accuracy is equal
or better than the specifications listed.
Standard Source
AC Current Calibrator
Multimeter
50 Turns Current Coil
A one-year interval is adequate for most applications. Accuracy specifications are war-
ranted only if adjustment is made at regular calibration intervals. Accuracy specifications
are not warranted beyond the one-year calibration interval. Keysight does not recommend
extending calibration intervals beyond two years for any application.
