value. The upper display will now show the offset value. You can offset
temperature up to

7.2.3 Setting manual temperature compensation
Note: This option is not available when the controller is set for ATC
operation.
For manual temperature compensation, two
different temperatures: process and
calibration, can be input independently. This
allows calibration at a temperature other than
the process temperature. Example: setting a
calibration temperature of 25
o
C allows
calibration using standard buffer solutions at
25
o
C, even if the process temperature is
different.
1) Select “ATC oFF” as described above in
section 7.2.1
2) Press the ENTER key. The upper display
shows the current process temperature and the lower display shows “P.
o
C”
to indicate process temperature.
3) Press the
∆∆∆∆
or
∇
∇
∇
∇
keys to adjust the process temperature value, between
–9.9 and 125
o
C.
4) After setting the process temperature value, press the ENTER key. The
upper display shows the current calibration temperature and the lower
display shows “C.
o
C”.
