APPENDIX B
Programming an Offset Parameter into a JUMO dTRON 316 temperature controller
If the temperature displayed by your replacement Jumo 316 controller does not match the
actual chamber temperature, an offset parameter may have to be programmed into the
controller. To do this, follow the steps below:
1. When the controller is in its normal mode, press the
PGM
button once.
2.
OPr
should be displayed.
3. Press the _ button twice.
ConF
should appear.
4. When
ConF
is displayed, press the
PGM
button once.
iNP
should appear.
5. Press the
PGM
button twice.
SEnS
should be displayed.
6. Press the _ button twice.
OFFS°C
should be displayed.
7. To adjust the offset value, press the
PGM
button (
OFFS
flashes), then use the _ button
to increase the OFFS value, or the _ button to decrease the OFFS value.
(If, for
example, the temperature display was originally reading 2.0° too high, you need to put a
negative offset value in of -2.0.
If the temperature display was originally reading 1.0° too
low, you need to put a positive offset value in of +1.0).
8. When the desired offset has been entered,
wait a few seconds
and the display will blink
to confirm the new offset parameter has been stored.
9. Press the
EXIT
button four times.
10. The current chamber temperature will then be displayed which will include the additional
offset value that you have just programmed in.
11. If at any stage during this procedure, the buttons are not pressed for 10 seconds or more,
the controller will automatically return to its normal mode and you will have to restart
from step 1.
