M51
Set start time, interval and go on (run) time of the logger
M52
Select memory
0. To RS232
1. To Buffer
2. Buffer => RS232
The RS232 signal is transmitted via the USB interface.
M53
View saved data in internal memory; navigate through data using Reset, Back,
Up and Down keys; indication is updated automatically if logger has been
activated

press Reset to go to the next digit
M61
View software version and serial number (ESN)
M62
Setup USB interface:

Parity None, Odd or Even
M67
Select frequency range for output between 0 and 9999, default setting is 1 to
1001 Hz
M68
Set volume flow for lowest frequency
M69
Set volume flow for highest frequency
M70
Set display backlight; select how many seconds backlight will glow without
keystroke
M72

Activate or deactivate Auto Power Off function (device powers off after 4
minutes of inactivity to save energy)
M90
View signal strength, signal quality, time ratio in the upper right corner
M91
View ratio between measured and calculated total transit time; if all pipe
parameters have been entered correctly and the sensors have been installed
correctly, the ratio should be around 100 % ±3 %; if not so, check all
parameters and sensor installation
M92
View estimated fluid sound velocity; if there is an apparent difference to the
actual fluid sound velocity, check all parameters and the sensor installation
M93
View total transit time and delta time (transit time difference)
M94
View Reynolds number and pipe factor the device uses
M+0
