Display CL current output. The display of 10.0000mA 

indicates that CL current output value is 10.0000mA. 
If  the  difference  between  displaying  value  and  CL 

output value is too large, the current loop then needs 

to be re-calibrated accordingly.

ESN 

Display  electronic  serial  number  (ESN)  of  the 

instrument. This ESN is the only one assigned to each 

Flowmeter ready to leave the factory. The factory uses 

it for files setup and the user uses it for management.

Serial Port Settings   

This window is used for serial port setting. Serial port 

is  used  to  communicate  with  other  instruments.  The 

serial  port  parameters  setting  of  the  instrument  that 

applies the serial port connection must be consistence. 

The  first  selected  data  indicates  baud  rate,  9600, 

19200, 38400, 56000, 57600, 115200 are available. 
The  second  option  indicates  parity  bit,  None  (No 

verification). 

Data length fixed to 8; 

Stop bit length for a fixed length. 

The  factory  default  serial  port  parameter  is  "9600,
