Module Initialization

EEPROM chip U342 on the Control Board stores the module's GPIB address and model number as well as other constants. The EEPROM was programmed with the proper constants at the factory. If the Control board or the EEPROM chip (U342) is replaced, the module must be reinitialized with the proper constants by programming the following commands in the order indicated. After it has been initialized, the module must also be recalibrated as described in the Operating Manual.
