4) Press the
∆∆∆∆
or
∇ ∇ ∇ ∇
keys to scroll the lower display to match the correct
value. The upper display will now show the offset value. You can offset
temperature up to
±
5
o
C.
5) Press the ENTER key to confirm your selection.
6) Continue with additional Advanced Set-up procedures, or return to the
Measurement mode by pressing the
∆∆∆∆
and
∇ ∇ ∇ ∇
keys (escape) simultaneously.
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
∇
∇ ∇
∇
ke ys 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”.
