Hi

Wait at least ten minutes for the reading to stabilize and press ENTER to
acknowledge the value. Press ENTER again to conclude the calibration. If the
calibration has been successful, the following message appears:
The correction data has now been calculated and stored in the HMI41 memory.
The HMI41 returns automatically to the selection of the display units, and can
be turned off. When the indicator is used as a standard indicator and the
correction data differs from the factory settings, an arrow in the upper
righthand corner is displayed:

If the message “cal pass” does not appear (instead, some other text may
appear, e.g. “too close”, “err offst” or “err gain”), the correction has not been
stored in the memory. The error may be due to an incorrect reference value or
to measured values that are out of the range.
