Similar to the voltage calibration, the software allows this current adjustment to be made
in 100, 10 or 1 count increments. Since the exact current increment per voltage count
varies from output to output and from instrument to instrument, you will need to
measure the change in the current with a current meter placed in series with the output
circuit (Figure 6-3).

NOTE
Do not exceed 60 V between current loop outputs and instrument ground.
To adjust the zero and span values of the current outputs, activate the ANALOG I/O
CONFIGURATION MENU (see Section 6.7.1), then press:

to the previous
menu.
Increase or decrease the current
output by 100, 10 or 1 counts. The
resulting change in output voltage is
displayed in the upper line.
Continue adjustments until the correct
current is measured with the current
meter.

EXIT ignores the
new setting, ENTR
accepts the new
setting.
