54 is fitted with a four-pole connector under the cover. The cover is supplied with a factory seal, and
in connection with verified sensors it will be a laboratory seal (legal seal). Thus, it is not possible to access the
connector without breaking the seal.
The connector is used for:
•
Meter programming, including adjustment of correction curve by means of METERTOOL
•
Bringing the sensor into test mode
•
Reading accumulated water quantity in connection with calibration
•
External control of start/stop in connection with calibration
The interface connector is constructed as shown in
Figure 20.
