SUMMIT 8800 STREAM CONFIGURATION 06
None No functionality or transmitter selected, the option will be skipped.
Keypad The user defined value for this range will be chosen.
Sensor 1-3 The transmitter value, as configure in hardware, will be used.
Average Average value of all transmitters (selected in DP sensor) will be used.
Serial Value as sent by Modbus e.g. from a PLC, or smart transmitter will be used.
Last good value The last good value known before loss of signal will be used.
Station A temperature as defined under the station/temperature tab
A selection could look like:
Figure 94 Stream temperature selection
Sensors The number of sensors connected to the SUMMIT
Keypad The default value which can be used in the selected
Max, Min The alarm limits for the temperature. If only one of the two must be used, see
advanced.
Hi, Lo The warning limits for the temperature. If only one of the two must be used, see
advanced.
Select The 6 choices for selection of the temperature source
6 .7 .1 Sensor calibration constants
The calibration range and offset are the scaling factors for the transmitter, determined during
the calibration of the transmitter. As this is a multiplier to the normal transmitter range and
offset, this is not a mandatory setting, but a software calibration. This is used to correct the
transmitter value without actually calibrating the transmitter itself. The advantage is that the
changes will appear in the audit log.
This setting is also ideal for simulation purposes. With it, the transmitter can be set to any value
without an actual transmitter connected.

Range Default value is 1. This is a multiplier to the actual transmitter range.
Offset Default value is 0. This is an offset to the actual transmitter range.
