M90
Display signal strength, signal quality, time ratio on the upper right
corner.
M91
Displays the Time Ratio between the Measured Total Transit Time and
the Calculated time. If the pipe parameters are entered correctly and
the transducers are properly installed, the ratio value should be in the
range of 100
±
3%. 0therwise the entered parameters and the
transducer installation should be checked.
M92
Displays the estimated fluid sound velocity. If this value has an obvious
difference with the actual fluid sound speed, pipe parameters entered
and the transducer installation should be checked again.
M93
Displays total transit time and delta time(transit time difference)
M94
Displays the Reynolds number and the pipe factor used by the flow
rate program.

M97
Command to record the pipe parameters entered by the user either to
the built.in data logger or to RS-232C serial interface
M98
Command to record the diagnostic information either to the built.in
data logger or to RS-232C serial interface
M99
Command to copy the current display either to the built.in data logger
or to RS-232C serial interface
M+0

time with the flow rate at the time of power on and off
M+1
Displays the total working time of the instrument
M+2
Displays the last power.off date and time
