Temp cal C41: T1/T2 Window to display temperature for supply line and return line.
C42:
Calibrate
Window to calibrate temperature sensors. User must enter password. Use resistors
to recalibrate sensors.
M Site
M11: Save
Site
Window to store the pipe parameters into the internal NVRAM (non-volatile
memory).
M12: Recall
Site
Window to recall the previously saved pipe parameters
M13: Delete
Site
Window to delete previously saved pipe parameters
Diagnosis M21: Triplet
Window to display the signal strength, signal quality and transit time ratio.
M22: Sound
Speed
Window to display the estimated sound speed of the fluid in the pipe. If this value has
an obvious difference with the actual fluid sound speed, the user is recommended to
check if the pipe parameters are correct and if the transducer installation is good.
M23:
Transit-time
Window to display the total transit time and delta time (transit time difference
between upstream and downstream traveling).
M24:
Reynolds
Window to display the Reynolds number and the pipe factor used by the flow rate
measurement program. Note, the pipe factor is rarely used.

Freq
Range
Window to set up the frequency range (lower limit and upper limit) for the
frequency output. Valid values: 0Hz-9999Hz. Factory default is 1-1001 Hz
Freq
Min
Window to set up the minimum flow rate which corresponds to the lower
frequency limit of the frequency output.
Freq
Max
Window to set up the maximum flow rate which corresponds to the upper
frequency limit of the frequency output.
M36: Buzzer Window to set up the buzzer.
If a proper input source is selected, the buzzer will beep when the trigger event
occurs
