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
M60 View date and time (calendar for 99 years); press ENTER to make changes;
press Reset to go to the next digit
M61 View software version and serial number (ESN)
M62 Setup USB interface:
Baud rate from 75 to 115200 bps
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 Reset working timer; press ENTER and confirm by selecting YES
M73 Set low value for alarm #1; there are two alarms; alarm output can be set via
M77 and M78
M74 Set high value for alarm #1
M75 Set low value for alarm #2
M76 Set high value for alarm #2
M77 Set up acoustic signal
M82 Date totaliser (by day, month or year)
M85 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 Read out 64 recorded data (Switch-on / switch-off date and time, time at which
flow was measured)
M+1 View total operating time of device
M+2 View date and time of last switch-off
M+3 View last volume flow before switch-off
M+4 View how often device was switched on
M+5 Scientific calculator (complicated to use)
M+6 Set flow velocity
M+7 Select protocol
M+8 Waveform of the received signal (identical with M06)
