When checking chamber TC for 121
º
C (250 F) it shows 121
º
C (250 F)
The temp for 134
º
C (273 F) needs correction without changing the accurate Temp of
121
º
C (250
º
F)
The data should be set as follows:
Upper Row
A 121 (250) R 121 (250)
A 132 (270) R 134 (273)
The system calibrates the new Offset and Gain and loads them into the non-erasable
memory.
As a result, while running a 134
º
C (273 F), program the correction is automatically
made, while at 121
º
C (250 F) there is no change.
9.10.2 An Example of Temperature Calibration:
Sensor no. 1 reads
– 60
º
C (140°F) and the actual temperature is 65
º
C (149°F) (in the
lower range), and in the upper range reads 130
º
C (266°F) and the actual temperature is
135
º
C (275°F).
In order to calibrate and to change the values do the following:
1. Press OPTION (F2).
2. Press CALIBRATION (F2).
3. The system will ask an entering code, enter the code.
4. Temperature 1 is displayed. To change temp 1, enter the code and
press ENTER
– (F3); several numbers will appear on screen. On the
left side of the uppermost row, a cursor appears which enables the user
to change temperatures.
5. Insert the actual temperature that was measured 65
º
C (149°F) and
press ENTER (F3); the cursor will point to the Read temperature
– R.
(upper right) Insert the read temperature, which was measured in the
autoclave 60
º
C (140°F), and press ENTER. The cursor will point to the
actual
–the lower left number.
6. Insert the actual temperature that was measured 135
º
C (275°F) and
press ENTER (F3), the cursor will point to the Read temperature
– R
(lower right). Insert the read temperature, which was measured in the
autoclave (130
º
C), and press ENTER. Pressing ENTER will bring you
to the calibration of temperature 2.
– If you want to calibrate
temperature 2 repeat all calibration steps, if not, press ENTER until the
main screen is displayed.
