1 Calibration Point
Refer to Calibration section.
Code 322 Flow Calibration (Multiple Point)
Factory programmed value:
No Values Entered
Options:
2 to 10 Calibration Points
This code allows for the display to be calibrated at multiple flow rates. This function
should be used when the flow sensor is installed in a difficult plumbing location where
flow is not linear. It corrects for nonlinear flow to provide an accurate flow rate display.
Refer to Calibration section.
Error Code E202
An invalid program code has been entered. Re-enter program code when the digital
display resets.
Error Code E204
There is no signal from the sensor. This code will only be displayed when in a
calibration mode. Troubleshoot the sensor and the associated wiring.
Error Code E206
A selected calibration point is to close to the previous point. (There is less than
5% difference between two calibration points.) Select a different point to continue
with the calibration procedure.
Error Code E208
There is a failure with the internal memory of the module. Contact FRC if this
error code is displayed.
Exit Program Access Mode
