Micromod Micro-DCI: 53ML5100A LOADING STATION - Manual (Page 49)

5.3 CALIBRATION
The instrument’s analog inputs (ANI0&1) and analog outputs (ANO0&1) normally do not require re-
calibration. If it becomes necessary to recalibrate the instrument, due to the inadvertent change of
the stored calibration values, then this can be accomplished by altering their respective datapoints.
The calibration zero and span datapoint locations are as follows:
ANI0 ANI1 ANO0 ANO1
Calibrate Zero B263 B264 B267 B268
Calibrate Span C296 C297 C300 C301
Note: The spans have a nominal value of 1.0 and can be adjusted
up or down within the range of 0.8 to 1.2. The zeros have a nom-
inal value of 128 and can be adjusted up or down within the range
of 100 to 150.
5.4 ERROR AND HARDWARE MALFUNCTION MESSAGES
• Entire Display Flashes - The watchdog timer has timed out.
• CPU RAM FAILURE - IC U1 failure.
• ROM CHKS FAILURE - IC U3 failure.
5.5 RESETTING THE INSTRUMENT
The instrument can be reset either by cycling the power, or by carefully pressing the reset button
with a thin wire, such as a paper clip, inserted through the small reset hole in the upper left corner
of the front bezel. (See Figure 1-2 for the location of the reset hole.) When the instrument resets,
it immediately checks to determine if any of the horizontal keypad push buttons are held pressed.
•
If the 1 push button is held pressed during instrument reset, the instrument enters a factory
test mode. The test mode can be exited by resetting the instrument again using the paper
clip with no push buttons pressed.
•
If the 2 push button is held pressed during instrument reset, the instrument database is set
to the defaulted values. To default the database, perform the following steps:
1. Press the 2 push button and DO NOT RELEASE IT.
2. While the 2 push button is still held pressed, use a paper clip to press the reset
button. DO NOT RELEASE the 2 push button.
3. The display goes all black and then the default display appears.
4. Release the 2 push button. (The database is reset to the default values with
the default display present on the instrument.)
