Changing Temperature Scale Between °C And °F - Thermo Scientific CC58114PC Installation And Operation Manual

Operation - UT150 Controller
Changing Temperature Scale Between °C and °F
1. *outside of the process tube, operate the oven or furnace chamber to your
normal stable temperature setpoint, which an independent temperature
measurement setpoint, with an independent temperature measurement device
located in the center of chamber. The controller will be "running" the program
or operating in the local mode to maintain the temperature.*
2. Note any difference in the controller's measured temperature (upper value) UV
and the independent measurement. If a difference of greater than 1°C is noted
proceed with the following steps. If less than 1 °C, no change.
3. Press and hold the "SET/ENT" button for 3 seconds to display "modE"
4. Verify the button lockout parameter will give access to make this display offset.
Press and release the "SET/ENT" button twelve times to display "LoC". The
value 0 (zero) displayed will give full access and is necessary to make the
display offset changes desired. If the value displayed is 1 or 2, use the "down
arrow" button to make 0 (zero) press release the "SET/ENT" button to register
this change.
5. Press and release the "SET/ENT" button twelve times to display "bS" and the
current offset value.
6. Allocate the offset value and select with the arrow buttons that is needed to
make this controller display correctly. For example, if the independent
measurement is 553 °C, the controller Temperature measurement display
shows 550 °C, and the current controller offset (bS) is -2, then make controller
display offset "+1" [(+3 needed offset) + (-2 current offset) = (+1 new offset)].
7. Press and release the "SET/ENT" button once to register this new offset value.
Press and hold the "SET/ENT" button for 3 seconds to exit this controller
menu.
8. Operate the controller to the same temperature to stabilize the chamber to
check for any further variations between the controller and the independent
measurement. Repeat steps 2 - 7 as necessary.
9. This completes the display offset procedure for the Yokogawa model UP150
temperature controller. If the bottom lockout parameter "LoC" was originally on
a value of 1 or 2, repeat steps 3 & 4 to return to this original value.

Changing Temperature Scale Between °C and °F
To change the temperature scale in the UP150 controller to operate on °F instead
of the factory setting of °C, or from °F to °C, Follow these steps.
These change will alter the controller input type and associated scale-dependant
parameters, and erase the stored program to default values. Please document the
stored program in the controller before proceeding.
