e. When the ready indicator turned on, stop the block cooler system.
f. Press the “Offset” key and by using temperature up and down key adjust the desired
offset value (The difference between block cooler system temperature and the user’s
calibrated thermometer). Upon setting the offset value press the “Offset” key again
Note:
The maximum adjustable offset range is ±12.5
℃.
While the system is in the offset function user will not be able to start the system. User
will need to press the “Offset” key again to quit the offset function and back to main
menu (Block Cooler CB-1 Set Temp.).
g. Start the block cooler system. Wait (~15 minutes) until the system achieves the
desired temperature (4
℃
) and stabilized (Ready indicator turned on).
h. When the ready indicator turned on ensure the temperature reading on the users
calibrated thermometer is as per to the previously entered offset value or else repeat
step (e) – (h).
Example:
Assume upon stabilizing the block cooler system temperature, user’s
calibrated thermometer temperature displays 6.5
℃
and the block cooler LCD displays
4
℃
. The offset value that user needed to enter is -2.5
℃
. Operator shall stop the
system and press offset key and press temperature down key to -2.5
℃
(6.5
℃
-2.5
℃
=
4
℃
) then press the “Offset” key again to quit the offset mode. Then start the block
cooler system and wait until the system temperature stabilize and ensure the reading
temperature value on the user’s calibrated thermometer is as per to the offset
adjustment value previously made.
