Mohr CT100B Series - Operator Performance Checks; Required Equipment

B. Operator Performance Checks
B.1. General Information
The CT100B Operator Performance Checks are a series of procedures used to verify the calibration
of a CT100B TDR. The following series of checks should be performed after a unit has been newly
calibrated to verify compliance to published specifications, but may also be performed to determine
if calibration is required. It is recommended to perform these checks at least every 6 months.
See Section E.4 for more information on calibration.
The following series of steps is designed to allow a CT100B operator to completely verify the
properties of an individual CT100B unit to each published specification. Throughout this
procedure any references made to the CT100B should be considered applicable to the CT100HF
and CT100S.
NOTE: Operator Performance Checks should not be considered CT100B
calibration.
NOTE: If a CT100B fails any Operator Performance Check, it should be
serviced by a qualified repair facility.
