Model 2701 Service Manual
Calibration
2-19
Manufacturing calibration
The manufacturing calibration procedure is normally performed only at the factory, but the
necessary steps are included here in case the unit is repaired and the unit requires these calibra-
tion procedures.
NOTE
If the unit has been repaired, the entire comprehensive calibration procedure should
also be performed in addition to the manufacturing calibration procedure.
Recommended test equipment
Table 2-13
summarizes the test equipment required for the manufacturing calibration steps.
In addition, you will need the calibrator (see
Table 2-1
) and signal generator to complete the
comprehensive calibration steps.
Calibration card preparation
Before performing manufacturing calibration, short the HI, LO, SHI, and SLO terminals of
TE100 on the Model 7797 Calibration System card together using the supplied jumpers. (See
the Model 7797 documentation.) These connections will form a low-thermal short necessary
for the manufacturing calibration procedure. The Model 7797 should then be installed in
scanner Slot #1.
Unlocking manufacturing calibration
To unlock manufacturing calibration, press and hold in the OPEN key while turning on the
power.
