10. Service

The SERVICE MENU contains three submenues: INFORMATION, FORCE OUTPUT and SIGNAL
INFORMATION. INFORMATION contains all identification data of the signal converter and sensor.
Note that the meter continues to measure and update the outputs(s) while in the SERVICE MENU.
The only exception is when an output is set in the FORCE OUTPUT MENU.

In FORCE OUTPUT it is possible to set all outputs to fixed values. The current output can be set
to between 0/4-20 mA, the frequency/pulse output can be set to 1 Hz and the relay output can be
switched on or off.

In the SIGNAL INFORMATION menu it is possible to read information regarding the ultrasonic
signals, the flow signals and the transducers.
In the TIME/FLOW menu it is possible to read the average transmission time, i.e. the time it takes
for the sound to pass between the two transducers at zero flow in the pipe, the time differential and
the average flow rate in the track.
In the SIGNAL RECOGNITION menu it is possible to read the correlation coefficient of both the
transmission time and the difference time. The correlation coefficient is a number between 0 and
±1. A number close to 1 denotes a good correlation between the two signals. The DETECTION
COEFFICIENT states the quality of the transmission time analysis. The CROSS DETECTION
COEFFICIENT states the quality of the time difference analysis.
