Piping: Connect the piping as described in “Offline validation exclusive” in
section 9.4.1.
Configuration: Configure the offline validation (see section 9.4.2) for validation 1 and 2.
Automatic execution configuration: Configure from the following menu as necessary.
[HART] “Detailed setup>>Validation>>Offline validation 1+2”
[YH8000] “ >>Configuration>>Validation>>Offline Validation 1 + 2”
Semi-automatic execution menu path:
[HART] “Diagnosis/Service>>Validation>>Semi-auto>>Semi-auto offline val 1+2”
[YH8000] “ >>Execution>>Validation>>Semi-Auto>>Offline Validation 1 + 2”
Time chart: The valve operation during offline validation 1+2 execution and the timing when
