6.4 About the Numerical Data Units in the message
Any units can be chosen for numerical data in data communication with the host system (PC, etc.). Take
a pressure unit Pa, for example, when Pa ( "PASCAL" ) is your setup option pressure unit on the host
system (PC, etc.) side, then the pressure-related numerical values in data communication will read in Pa
across the board.
For this reason, all unit-dependent numerical values (temperature, pressure, instant
fl
owrate, etc.) are
paired with corresponding unit codes before they are transmitted.

6.5 About the Numerical Data Format in Data Transmission
Numerical data format in data transmission basically come under the following two styles where all
characters use the ASCII code with decimal point eliminated.
①
Standard format
Numerical data format generally uses an "exponential representation".
・
Mantissa sign 1 digit
・
Numerical value in mantissa 6 digits
・
Exponent part sign 1 digit
・
Numerical value in exponent part 2 digits
②
Special (accumulated total) format
Total counter pulse uses the following format.
・
Integer part 10 digits (effective data 8 digits)
