FDT-25W Wall Mounter Ultrasonic Flowmeter
M82 window for viewing date totalizer.
M90~M94 are diagnostic windows for a more accurate measurement.
M97~M99 are not windows but commands for the outputting of display copying and pipe parameter
setups.
M+0~M+8 are windows for some additional functions, including a scientific calculator, viewer on
records such as total working hours, turn-on and turn-off times, dates and times when the
flow meter has been turned on or turned off.
Other menu windows such as M88 have no functions, or functions were canceled because they are not
applied to this version of the software.
The major reason why the menu windows are arranged in this way is that the software programmer
hopes that the menu window arrangement for this version can be compatibility with the previous
versions of the flow meter software. This will make it easier for the former version users with this flow
meter series.
