9. Press “Download” on the “System Configuration” screen to save the calibration
values to the flow meter. After the download is complete, power cycle the meter
to make the newly downloaded values take effect.
If the calibration points are not separated by at least 40°C or if either one or both of
the RTDs are open, the following error message appears.
Calibration points are too close. Calibration not usable.

OK
!
Check the RTDs resistance values with an ohmmeter to make sure they are not
shorted. See Table A-4.2 for typical RTD resistance values. Next check to ensure that
incorrect “Cal Point” values were not entered inadvertently.
