CALIBRATION OF SENSOR
The temperature on the temperature display shows the temperature of sensor for temperature display
attached to the monitor bottle (upper and lower).
Follow the procedure below when the calibration of the sensor for temperature display is necessary.
1.
Remove the cover on the monitor bottle as shown in
Fig. 1.
2.
Take out the sensor for temperature display from the
chamber.
The lower monitor bottle has a recorder sensor (left
side) as well. Care should be taken not to take out the
recorder sensor.
3.
Prepare a bottle or beaker with a solution of crushed ice
and cold water. Agitate the mixture thoroughly.
4.
Put the sensor for temperature display to be calibrated
in the mixture.
5.
Select the temperature display by pressing temperature
display changeover key to show the temperature of sensor
for temperature display to be calibrated
For the changeover of temperature display, refer to
page 17.
6.
While sometimes agitating the mixture, allow the temperature indicated on the temperature display to
be stable.
7.
Calibration is needed if the temperature on the temperature display does not show 0
o
C.
8.
Press the calibration key (CAL) on the control panel for 5 seconds.
►
The temperature display shows C00.
9.
Set an identification code for sensor for temperature display by using the up arrow key ( ).
The identification code for upper sensor for temperature display: C01
The identification code for lower sensor for temperature display: C02.
<Important>
Never set any identification code other than C01, C02.
10.
Press the calibration key (CAL).
11.
Check that the temperature shown on the temperature display is approximately 0
o
C.
Repeat the above procedure through 6 to 10 if the temperature shown on the temperature display is
out of the range of 0±0.2
o
C.
12.
Take out the sensor for temperature display from the mixture and wipe it with a dry and soft cloth.
13.
Replace the sensor for temperature display and fix it with a cover.
Also replace and fix the recorder sensor to the lower monitor bottle.
