l
Parameter
Parameter name
(HART)
Description
Offval1 gas type Selects the type of validation 1 check gas (two-gas measurement only)
Offval1 gas conc Enters the concentration of the validation 1 check gas
Offval1 pres mode Selects the pressure mode for validation 1 execution (*1)
Offval1 pres fix val Enters the pressure for when Offval1 pres mode is set to Fixed
Offval1 temp mode Selects the temperature mode for validation 1 execution (*1)
Offval1 temp fix val Enters the temperature for when Offval1 temp mode is set to Fixed
Offval1 OPL mode Selects the optical path length mode for validation 1 execution (*1)
Offval1 OPL fix val Enters the process optical path length for when Offval1 OPL mode is set to Fixed

Fixed value: Set to a fixed value
l
Valve
Parameter name
(HART)
Description
Offval1 auto vlv man Selects whether to enable automatic valve control through the SV terminal during

9.4.3 Execution
Before starting offline validation, check that the piping and offline validation settings are correct.
Here, offline validation 1 will be used as an example.
Execution menu path:
[HART] “Diagnosis/Service>>Validation>>Manual>>Manual offline val 1”
[YH8000] “ >>Execution>>Validation>>Manual>>Offline Validation 1”
(1) Starting an offline validation
On HART or YH8000, open the above menu, and start offline validation. If automatic
valve control is enabled, a message stating that the valves will be automatically controlled
will appear.*1 In this case, you do not need to manually control the valves during offline
validation.
