Input – Span Calibration
To perform a span calibration on an input, verify
that the “Span” option at the top is selected.
Select the target millivolts that will be sourced.
Note – For a span calibration, it is recommended
that 90 % of the full range be sourced
. The
recommended millivolt source value will be
displayed as well. The mV value will be displayed
on the screen. Press the Calibrate button to
begin the calibration. The calibration status will
be displayed on screen. When it is over, the
screen will display “idle” once again.
Output – Zero Calibration
To perform a zero calibration on an output,
verify that the “Zero” option at the top is
selected. Press the Ready button to begin
the process. Enter the mA value that is being
measured at the appropriate terminals (see
the
9120 Wiring Terminals section; the
appropriate terminals to measure will also be
displayed on the screen). Press the Calibrate
button to finish the calibration. The calibration
status will be displayed on screen. When it is
over, the screen will display “idle” once again.
Once the zero calibration has finished, the
span calibration can be performed.
