16. Press the Done softkey to accept the calibration
parameters. The display changes to:

17. You now have the choice of starting an
automatic test or stepping through the test points
manually. Press the Auto Test softkey to have
the calibrator run through the tests automatically.
(
Abort gets you out of the calibration procedure.)
The tests begin at the zero point, sourcing the
correct temperature (a voltage) and measuring
the corresponding current from the transmitter.
As soon as a measurement has settled and been
captured, the calibrator moves to the next step.
Because the calibrator waits for the
measurement to stop changing, the Auto Test
works correctly for instruments with built-in
damping. The error of the expected measured
value is shown in the top left of the measure
window.
18. The calibrator moves to the remaining set of
points. For temperature and electrical parameter
calibration, the points are done automatically. If
you are sourcing pressure, the calibrator pauses
at each step for you to adjust the pressure
source. When the tests are complete, an error
summary table such as the following is
displayed.
