3.14 :CALibration subsystem
There are two calibrate commands that are accessible to the operator. These commands are used
to null out input bias current and voltage burden. These commands are summarized in Table
3-5. To calibrate the instrument, refer to the Model 6517 Service Manual.
:VOFFset
:CALibration:UNPRotected:VOFFset Null voltage burden
Description This action command is used to null voltage burden. Before sending this command connect a
short to the input triax connector. Function changes and measurements cannot be made during
the calibration process.
:IOFFset
:CALibration:UNPRotected:IOFFset Null input offset current
Description This action command is used to null input offset current. Before sending this command, cap the
input triax connector. Function changes and measurements cannot be made during the calibra-
tion process.
