10.7 Diagnostic functions
10.7.1 Read min/max values
►
Select [Lo�x] or [Hi�x] to display the highest or lowest process value
measured:
-[Lo�F] = min� value of the flow volume measured in the process
-[Hi�F] = max� value of the flow volume measured in the process
-[Lo�T] = min� value of the temperature measured in the process
-[Hi�T] = max� value of the temperature measured in the process
-[Lo�P] = min� value of the pressure measured in the process
-[Hi�P] = max� value of the pressure measured in the process
Delete memory:
