High and low limit setting requirements: lower range value (LRV) and upper range value (URV) must be set within the lower and upper range limits, ｜URV-LRV｜≥ Minimum Range *The overload values refer to the maximum overload range of the sensor. The maximum overload range of the transmitter ultimately depends on the pressure rating of the process connection.
