Firmware Revision Query

The multimeter has three microprocessors for control of various internal systems. You can query the multimeter to determine which revision of firmware is installed for each microprocessor.

•The multimeter returns three numbers. The first number is the firmware revision number for the measurement processor; the second is for the input/output processor; and the third is for the front-panel processor.

•Front-Panel Operation:

8:REVISION (SYS MENU)

REV XX-XX-XX

•Remote Interface Operation:

*IDN? returns “HEWLETT-PACKARD,34401A,0,XX-XX-XX”

Be sure to dimension a string variable with at least 35 characters.
