Calibration Procedure.
Calibration procedure ensures that this instrument meets
the electrical specifications given in the Operators
manual. Where possible, instrument performance is
checked before an adjustment is made. For best overall
instrument performance when performing a complete
calibration procedure, make each adjustment to the
exact setting, even if the Check is within the allowable
tolerance.
Partial Calibration. A partial calibration is often
desirable after replacing components, or to touch up the
adjustment of a portion of the instrument between major
recalibrations.
