5.2.13 Setting Range Values for Applied Temperature
When setting the range values using applied Temperature, the URV changes
automatically to compensate for any changes in the LRV and to maintain the present span
(URV
– LRV). When entering the LRV using the Tookit keypad, the URV does not change
automatically.
If you use the applied temperature method, and need to change the LRV and URV,
change
the LRV first
. You can also use the local zero and span adjustments on the Transmitter to set
the LRV and URV values.

5.2.14 Saving device history
FDC provides you a feature wherein you can save the device configuration snapshot as history. This
history record may then be transferred to a central asset management database such as FDM.
Using this feature you can save the device configuration snapshot as device history of a connected
device at any given time in a predefined location. The following are the features of save device
history option.
Two formats of history are supported: FDM and DocuMint.
Only one snapshot per device instance is allowed to be saved and you can save the
snapshot of a device any number of times overwriting the existing one.
To save device history, perform the following steps.
1.
On Device Home page, tap Tools.
2.
Select
Save History
and tap
Select
The
Save History
