M45
Flow rate scale factor. The default value is ‘1’.
Keep this value as ‘1’, when no calibration has been made.
M46
Networks address identification number. Any integer can be entered except 13(0DH,
carriage return), 10 (0AH, line feeding), 42 (2AH), 38, 65535.
Every
set of the instrument in a network environment should have a unique IDN.
Please
refer to the chapter for communication.
M42
Zero calibration/Zero point setup. Make sure the liquid in the pipe is not running
while
doing the setup.
M43
Clear the zero point value, and restore original value.
M44
Manual Zero point . Set up a flow bias. Generally this value should be 0.
M47
System locker to avoid modification of the system parameters.
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.
M48
Entry to linearity correcting data inputs. By using of this function, the non
-
linearity of
flow meter will be corrected. Correcting data shall be obtained by careful calibration.
M49
Displays the input contents for the serial port.
By checking the displays, you can know if the communication is ok.
M50
Switches for the built-in data logger. There are as many as 22 different items can be
chosen. To turn this function,
select ‘YES’ the system will ask for selecting the items.
M51
Time set for timing output.(data logger or printer)
M52
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
(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.
M53
Display analog inputs, AI5, current value and its corresponding temperature or
pressure or
liquid level value.
M54
Pulse width setup for the OCT (OCT1) output. Range from 6 mS to 1000 mS
M55
Select analog output (4-20mA current loop, or CL) mode.
M56
Set the value which corresponds to 4mA or 0mA output current (4mA or 0mA is
determined by the setting in M55)
M57
Set the value which corresponds to 20mA output current
M58
Current loop verification
Check if the current loop is calibrated correctly.
M59
Display the present output current of current loop circuit.
M60
Setup system date and time. Press ENT for modification.
M61
Display Version information and Electronic Serial Number (ESN) that is unique for
each
flow meter.
M62
RS-232/RS485 setup. All the devices connected
with flow meter should have matched
serial configuration.
M63
Select communication protocol.
Factory default is ‘MODBUS ASCII. this is a mode for MODBUS- ASCII, Meter
BUS,
Fuji Extended Protocol, Huizhong’s various protocols.
If you are going using MODBUS - RTU you have to select ‘MODBUS_RTU’.
M64
AI3 value range.
Used to enter temperature/pressure values that are corresponding to 4mA and 20mA
input
current. The display values have no unit, so that they can present any physical
parameter.
