Working timer. It can be cleared by pressing ENT key, and then select
YES. Before instrument shipped, We have calibrated and tested, so
working timer is usually not zero.
M73
Enter Lower Flow Rate value that will trigger the #1 Alarm. There are
two virtual alarms in the system. By “virtual” we mean that the user
must redirect the output of the alarms by setting up the output hardware
in M78 and M77
M74
Enter the higher flow rate value that will trigger the #1 Alarm.
M75
Enter the lower flow rate value that will trigger the #2 Alarm.
M76
Enter the higher flow rate value that will trigger the #2 Alarm.
M77
Buzzer setup. If a proper input source is selected, the buzzer will beep
when the trigger event occurs
M78
OCT (Open Collect Transistor )Output setup:
By selecting a proper input source, the OCT hardware will close when the
trigger event occurs

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%. Otherwise the entered parameters and the
transducer installation should be checked.
M92
Displays the measured fluid sound speed. Normally this value should be
approximately equal to the entered value in Menu 21 when M20 the fluid type
select “Other”. If this value has an obvious difference with the actual fluid
sound speed, pipe parameters entered and the transducer installation should be
checked again. If Menu20, the fluid type doesn’t select “Other”, this window is
no matter with user.
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.
