The Analog Output Calibrate Zero screen allows the user to calibrate
the zero state of the selected analog output. The operator must connect
a volt meter to the output and adjust the output until it reads 0.0 V
on the meter for a voltage channel, or either 0 or 4 mA for a current
channel (depending on the selected range). See the “set output to:” field
on the display.

The Analog Output Calibrate Full-Scale screen allows the user to
calibrate the full-scale state of the selected analog output. The operator
must connect a volt meter to the output and adjust the output until the
meter reads the value shown in the “set output to:” field, in either V or
mA, depending on the selected output channel.

The Analog Input Calibration menu is used to calibrate the 8 analog
input channels at both zero and full-scale. The analog input calibration
menu is visible only when the I/O expansion board is installed and
when the instrument is in service mode. For more information on the
service mode, see “ Service Mode ” earlier in this chapter.
Note
This adjustment should only be performed by an instrument
service technician.
