CODE 12: Setting of Gas Pressure

This setting defines the zero and span points of the pressure transmitter's measurement range.

(a) Setting of zero-point gas pressure

[

*Z_PRS

]

Configurable range: 0.01 to 999.99 (for kPa),

0.0001 to 9.9999 (for MPa),

0.015 to 99.999 (for psi )

(b) Setting of span-point gas pressure

[

*S_PRS

]

Configurable range: 0.10 to 999.99 (for kPa),

0.0001 to 9.9999 (for MPa),

0.015 to 99.999 (for psi )

The zero and span points set here are also used for the analog output.
