6 Calibration
Routine calibration should be performed every 12 months. Non-routine calibration is only
required if a related assembly is replaced or if the periodic calibration is unsuccessful.
Calibration can be performed through the front panel by putting the 2001RP in Calibration
mode (CAL mode) or over the RS232C or IEEE-488 bus if the interface option is installed.
For bus calibration, the PGUI32 program may be used. Refer to the PGUI32 help file
supplied with the program for instructions on calibration over the remote control bus.
All routine calibrations can be performed without removing the top cover (Closed case
calibration). For the LZ option, program 135V or 270V for 150V or 300V respectively.

Some 2001RP-AV may be factory configured for single voltage range only. In this case, the 230 V
range is not available.
