5.4.2 Collecting and entering temperature data
When collecting data, keep in mind that “A” is always the
actual temperature and “R” is always what is being displayed
on the digital screen of the autoclave.
Once in the calibration mode, the calibration screen will look
similar to this:
Upper Row: A 140.0 R 140.0 (lower temp reading °F)
Lower Row: A 266.0 R 266.0 (higher temp reading °F)
When entering data, remember that the upper row will
represent the lower temperature of the chamber and the bottom
row will represent the higher temperature of the chamber.
5.4.2.1 Collecting temperature data
— Select the low setting on the PT100 simulator
(it is suggested to use 158°F)
This will be the “A” value for the upper row.
— Record the temperature displayed on the screen
(there can be a slight delay in updating the screen
when changing values on the PT100 simulator)
This will be the “R” value for the upper row.
— Repeat this procedure for the high setting using
the PT100 simulator (it is suggested to use
266°F)
These values will be for the bottom row
— Once the data is collected disconnect the PT100
simulator from JP2 and reconnect the PT100.
5.4.2.2 Entering temperature data
Access the calibration mode as described in para
5.4.4.
— The cursor will appear flashing under the value
for “A” in the upper row.
— Using the UP/DN arrow keys, enter the value
for “A”. This will be the first temperature value
that the PT100 simulator was set for.
— Press the PROGRAM key to advance to the
next value.
— The cursor on the upper row will move one
position to “R”; now enter the first temperature
value recorded from the display
— Press the PROGRAM key to advance to the
next value that will be in the bottom row.
— The cursor will be positioned under the value
for “A” in the bottom row.
