Performance Tests and Calibration 6

Adjustment recommendation

Specifications are only guaranteed within the period stated from the last
adjustment. Keysight recommends that re-adjustment should be performed
during the calibration process for best performance. This will assure that the
U1211A, U1212A, and U1213A clamp meters will remain within the specifications
for the next calibration interval. This criterion for the re-adjustment provides the
best long-term stability.
Performance data are measured during the performance verification tests but this
does not guarantee that the instrument will remain within these limits unless the
adjustments are performed.
Refer to "Adjustment count" on page 114 and verify that all the adjustments have
been performed.
