4.4 TEMPERATURE ADJUSTMENT
4.4.1 Temperature Control Summary
The temperature control CPU gets each unit’s temperature by A/D converted signal as a temperature from the
sensor.
Due to the voltage comes out from the temperature sensor is various, the Main CPU sends the Offset value to
the temperature control CPU for each sensor to get the temperature within the range.
4.4.2 Temperature Verification at Each Unit 4
The unit temperatures displayed on the Temp. Control screen are the temperatures at each thermister.
For the temperature adjustment, the actual temperature at each unit must be checked as follows.
4.4.2.1 Cooling section (Reagent Cooler)
After 30 minutes since turning power ON of CA-500, perform the following procedures.
1) Pour 4 mL of distilled water into DADE 1 mL bottle, and put it into position No.4 of reagent rack.
2) Measure temperature of the water, and confirm that temperature is within 15.0 +/-2°C.
4.4.2.2 Detector Block
After 30 minutes since turning power ON of CA-500, perform the following procedures.
1) Pour 150 µL of distilled water into two reaction tubes, and put it into detection well CH5 and
incubation well #6.
2) Measure temperature of the water, and confirm that temperature is within the following range.
Detection Well CH5: 37.0 +/- 0.5°C
Incubation Well #6: 37.0 +/- 1.0°C
(Measure the temperature after temperature of the water becomes stable.)
4.4.2.3 Reagent Nozzle 19
Perform the temperature adjustment for reagent nozzle after the temperature adjustments of the detector
block and reagent block are passed successfully.
1) Enter the service mode and select [Special Operate] Æ [Service] Æ [Adjust] Æ [Temp. Control].
2) Press "Nozzle" area and input the D/A value attached on the heated probe to "S:xxx" area.
3) To verify the Temperature refer to Section 5.5.4 Reagent Temp. for the procedures
Jump to Section 5.5.4
4.4.2.4 Room Temperature
1) Enter the service mode and select [Special Operate] Æ [Service] Æ [Adjust] Æ [Temp. Control].
2) Verify that the room temperature by thermometer is within the displayed temperature +/- 3°C.
3) Press [Return] key to finish the confirmation.
