Recommended test equipment
Table 17-13 summarizes the test equipment required for the manufacturing calibration
steps. Note that the equipment depends on the firmware revision level. See Table 17-1 for
equipment needed to complete the comprehensive calibration steps.
Extender board preparation
Before performing manufacturing calibration, short the output HI, LO, SHI, and SLO
terminals of the Keithley 7797 Calibration/Extender/Test Board together using clean,
solid copper wires. These connections will form a low-thermal short necessary for the
manufacturing calibration procedure. The Calibration Extender Test Board should then
be installed in scanner Slot #1.
Test equipment connections
Connections for steps requiring the calibrator are shown in Figure 17-5 and Figure 17-6
shows function generator connections. Refer to the test procedures for specific steps.
Unlocking manufacturing calibration
To unlock manufacturing calibration, press and hold in the OPEN key while turning on the
power.
