Press the (OK) key.
• Example: Enter K value obtained from the
equation (a). A value having up to 3
decimal places may be specified.
When h=+3 m, Fill fluid code A, span=15 kPa,
Note 1: The function is performed using a built-in temperature
sensor in the transmitter body. The temperature
deviation between the transmitter body and capillaries
should be minimized to achieve optimal performance
of the function.
Note 2: When the span changes, reenter the newly obtained
value of K to E11: TEMP ZERO.
