The user can also employ the ESN for instrumentation management.
The ESN is displayed in menu window M55, which can be accessed as follows: M

§4.27 How to calibrate the flow meter
There are 4 calibration functions for the RH40: Zero Calibration, Linear Calibration, 0/4-20 mA loop
calibration, and temperature calibration. These can be found by pressing the CAL key on the device.
1) For Zero Calibration, refer to Section 4.11.
2) Linear and 0/4-20 mA loop calibration are unavailable at this time. For updates, please contact
Spire Metering at support@spiremt.com.
3) For Temperature Calibration, normally, there is no need for such calibration, as the device is
calibrated in the factory. In case you need to re-calibrate the sensors, contact Spire Metering at
support@spiremt.com.
