13.Press the Done softkey to accept the calibration parameters. The display changes as follows:
14.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 has been captured, the calibrator moves on to the next step. Because the calibrator waits for the measurement to stop changing, the Auto Test works correctly for instruments with
