Introduction
This chapter contains the performance verification and calibration adjustment procedures
for the Product. Annual calibration verification and adjustment is recommended to make
sure the Product operates to specifications.
Calibration Correction Factors
You can use the Product as a standalone transconductance amplifier or as an extension to
the 6100B and 6105A series calibrators. There are two different modes of operation. The
calibration adjustment procedure has two phases and two sets of calibration factors.
When you operate the Product standalone only the standalone calibration correction
factors are applied.
The procedure to adjust the Product in standalone mode without a 6105A is given below.
Equipment necessary to adjust and verify the Product to full specification when
connected to a 6105A is not available commercially. A procedure to do a confidence
check is included in this manual. But to make correction adjustments for operation with a
6105A, you must send the Product to a Fluke Service Center.
Repair to the Fluke 6105A Electrical Power Standard or the Product must be followed by
a calibration at a Fluke Service Center. This is to make sure they operate to
specifications.
