Alarm Standby Function
The 7HI/7HK have an Alarm Standby function to allow masking of the process low alarm condition if the process variable has not traversed the low alarm threshold for the first time.

Measurement Offset
A programmable sensor offset is provided for instances when it is not possible to locate the sensor in the ideal location. This offset can be applied to all inputs and is programmable for °C or °F.
