6) Press
the
▲ or ▼ keys to scroll the lower display to

7.2.1
Setting Manual Temperature Compensation
NOTE: This parameter is blanked out when the controller is
set for ATC operation.
For manual temperature compensation, you can set two
different temperatures: Process and Calibration. This allows
calibration at a temperature other than your process
temperature. Example: setting a calibration temperature of 25
ºC lets you calibrate using standard buffer solutions at 25 ºC,
even if your process temperature is at different temperature.
1) Enter Advanced Set-up mode. Push the ENTER key and
(use
▲ or ▼ keys to) scroll to Advanced Set-up security
code “22”. Push the ENTER key again.
2) Press
the
▲ or ▼ keys to scroll until the display shows
“SEt ºC”. Push ENTER key.
3) Press
the
▲ or ▼ keys to select “oFF ATC”. Press
ENTER key.
4) The upper display shows the current process temperature
and the lower display shows “P. ºC” to indicate process temperature.
5) Press
the
▲ or ▼ keys to adjust the process temperature value. You can
adjust the value from -9.9 to 125 ºC.
