6.4 Board Exchange Procedure
6.4.1 Processor Board Exchange Procedure
The serial number of the LT Series oscilloscope is loaded in the real time clock
memory which is battery backed up. If it becomes necessary to replace the
processor board, the serial number must be loaded in the memory of the new board
by using LeCroy program " LeCalsoft " under GPIB remote control.
To run " LeCalsoft " type SKP.exe, in the main menu type S, and follow the
instructions, use five digits to enter the serial number ( i.e. 10281).
Then check in the system summary, by using the show status button on the front
panel, the scope serial number.
