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 ENTER key. Upper display shows current process temperature and
lower display shows “P.
o
C” to indicate process temperature.
3) Press
Δ or ∇ keys to adjust the process temperature value, between –9.9
and 125
o
C.
4) After setting the process temperature value, press ENTER key. Upper
display shows current calibration temperature and lower display shows “C.
o
C”.
5) Press
Δ or ∇ keys to adjust the calibration temperature value, between –9.9
and 125
o
C.
6) Press ENTER key to confirm.
7) Continue with additional Advanced Set-up procedures, or return to
Measurement mode by pressing
Δ and ∇ keys (escape) simultaneously.
