Block Cooler V1.0
12
E. OFFSET Function
OFFSET function can be utilized by operator to re-adjust the block cooler system temperature if
it is necessary. Due to the reason every block cooler system has been properly calibrated with
the calibrated digital thermometer before product delivery; operator is
ONLY
recommended to
use the OFFSET function as for the followings.
¾
Operator have the offset kit
¾
Operator have a standard calibrated thermometer
¾
Operator wish to alter the block cooler temperature as per to their external mercury
thermometer in order to follow a specific standard experimental conditions.
Note!
General laboratory mercury thermometer is not calibrated accordingly to
international standard thermometer. Some temperature variation may occur with the
usage of the different non calibrated thermometers.
Caution!
Maximum adjustable offset range is ±12.5
℃
. In any case if an operator notices the
system requiring more than the allowable offset range please contact your local Wealtec
representative.
In the case of performing any adjustments in the field, please follow the procedure below:
a. Open the protection lid and place the offset kit on top of the block cooler. Then place
the calibrated thermometer into the appropriate hole on the offset kit.
b. Switch on the block cooler system. Select the temperature parameter to 4
℃
.
c. Start the block cooler system.
d. Wait (~30 minutes) until the system achieves the desired temperature and stabilized.
