Analog Bus Correction Constants (Test 44)
This procedure calibrates the analog bus by using three reference voltages (ground,
+0.37 volts and +2.5 volts), then stores the calibration data as correction constants in
EEPROMs.
Analyzer warmup time: 30 minutes.

3. Observe the analyzer for the results of the adjustment routine:
• If the analyzer displays ABUS Cor DONE, you have completed this procedure.
• If the analyzer displays ABUS Cor FAIL, repeat the test.
4. If no more correction constant routines are going to be performed, return the A7 Switch
