4.1 HOW TO MEASURE THE ACTUAL TEMPERATURE
As the chamber is pressurized please use calibrated external measuring devices which are
•
independent of any cable (thermometer, data-logger, etc.).
Insert your measuring device on one of the shelves in the chamber.
•
Be sure that the sensor of your measuring device does not touch any metal part in the chamber.
•
Make the necessary adjustments and start the program.
•
If the temperature of the equipment and the temperature of the measuring device are different from
•
each other, please apply the calibration procedure as below:
4.2 CALIBRATION
4.2.1 OT 020 (Figure 1)
Press "value increase and decrease keys" (7 &8) together continuously until you see "0" on the
•
temperature display and any value on the time display.
Press "stop" (6) and pass to the 1
•
th
the 8
parameter.
th
At the 8
parameter press "stop" (6) continuously until you see "LC1" on the temperature display.
•
Press "time set" (4) you first see "HC1" on the temperature display, press "time set" again this time
•
you see "LC2" on the temperature display, press "time set" again you see "HC2" on the temperature
display. For the last time press "time set" and you see "JC" on the time display.
Press "stop" and change the value that appears on the time display according to the difference
•
between the equipment's display and the external sensor.
If the set temperature is 121°C and the external sensor measures 123°C, increase the value, which
appears on the time display, by adding 2; if the set temperature is 121°C and the external sensor
measures 118°C, decrease the value, which appears on the time display, by subtracting 3 by using
"value increase or decrease keys" (7 &8).
Press "stop" to return to stand-by mode.
