display is used as the display device.
Setup for local segmental LCD display. Enter 0 or 1 for the non-auto-scan mode;
Enter 2~39 for the auto-scan mode. In the auto-scan mode the display will
M3.
automatically scan displaying from 00 to the entered number of the local segmental
LCD display.
Flow rate damper for a stable value. The damping parameter ranges form 0 to 999
seconds.
M40
0 means there is no damping. Factory default is 10 seconds
M41
Low flow rate (or zero flow rate) cut-off to avoid invalid accumulation.
Zero calibration/Zero point setup. Make sure the liquid in the pipe is not running
M42
while doing the setup.
M43
Clear the zero point value, and restore the solidified zero point value.
M44
Set up a flow bias. Generally this value should be 0.
Flow rate scale factor. The default value is '1'.
M45
Keep this value as '1', when no calibration has been made.
Networks address identification number. Any integer can be entered except
13(0DH, carriage return), 10 (0AH, line feeding), 42 (2AH), 38, 65535.
M46
Every set of the instrument in a network environment should have a unique IDN.
Please refer to the chapter for communication.
System locker to avoid modification of the system parameters.
M47
If password is forgotten, you could send a command 'LOCK0' to the serial input to
unlock. Or you can write 0 to REGISTER49-50 under MODBUS protocol.
Entry to linearity correcting data inputs. By using of this function, the non-linearity of
M48
flow meter will be corrected. Correcting data shall be obtained by careful
calibration.
Displays the input contents for the serial port.
M49
By checking the displays, you can know if the communication is ok.
Switches for the built-in data logger. There are as many as 22 different items can
M50
be chosen. To turn this function, select 'YES' the system will ask for selecting the
items. There are 22 items available. Turn on all those items you want to output
Window to setup the time of scheduled output function (data logger, or
Thermo-printer). This includes start time, time interval and how many times of
M51
output. When a number great than 8000 entered for the times of output, It means
the output will be keeping always. The minimum time interval is 1 second and the
maximum is 24 hours.
Data logging direction control.
(1) If 'Send to RS485' is selected, all the data produced by the data logger will be
transmitted out through the RS-232/RS485 interface
M52
(2)
If 'To the internal serial BUS is selected, the data will be transmitted to the
internal serial bus which allows a thermal printer, or a 4-20mA analog output
module, to be connected to it.
Display analog inputs, AI5, current value and its corresponding temperature or
M53
pressure or liquid level value.
Pulse width setup for the OCT (OCT1) output. Minimum is 6 mS, maximum is 1000
M54
