Automatic Adjustment of Module Data
In order to match the data stored in EEPROMs on the respective modules to the complete instrument,
an automatic adjustment of module data is always necessary after replacing a module.
In addition to some standard information such as module name, serial number, hardware status and
date of manufacture, these stored data items contain important pieces of information within value tables
from module pre-testing, e.g. frequency responses for module error data.
This information permits to make the complete instrument ready for operation again (see also chapter 1,
Performance Test).
In the following, the preparations and the procedure of the automatic module data adjustment will be
explained.
Preparing the adjustment
Replacement of module(s): ½ Replace the faulty module(s) (see chapter 3, module replace-
ment).
½ Close the CMU casing (see chapter 3, module replacement).
½ Connect the CMU to the mains and switch on.
Performing the adjustment
Starting the version manager: ½ Note the startup in the display when switching on the CMU for the
first time.
½ When a beep can be heard three times, press the MENU
SELECT key.
The version manager is started (see also chapter 4, Firmware
Update). The display includes the menu item FIRMWARE
UPDATE AFTER BOARD CHANGE.
Procedure: ½ Press the softkey to the left of the above mentioned menu item.
The automatic adjustment of module data is started under software
control.
It may take a few minutes to additionally perform firmware updates
for microprocessors and programmable devices.
After the adjustment has been terminated, press the softkey to the
left of the EXIT menu item, the operating software starts and the
CMU is ready for use and can be operated in the usual way.
