17.7 Zeroing the RM Module
A zero calibration is carried out automatically every time when the module is switched on or
connected, and then 10 minutes after that. Then, a zero calibration is triggered every 30
minutes. You can also start a manual zero calibration when there is a drift in the zero: in the
[RM Setup] menu, select [Zero RM].
17.8 Calibrating the Flow Sensor
A calibration must be performed every time when the flow sensor is changed.
1. In the [RM Setup] menu, select [Calibrate RM >>].
2. Enter the positive factor provided on the flow sensor and select [Calibrate].
3. Enter the negative factor provided on the flow sensor and select [Calibrate].
4. After the calibration is completed successfully, the last calibration time and the message
[Calibration Completed!] are displayed. Otherwise, the message [Calibration Failed!]
is displayed.
