7.2 Temperature calibration (ATC mode only)
1) Select “ATC on” as described above in Section 7.4.1.
2) Press the ENTER key. The upper display indicates the
current temperature offset. The current measured temperature is
2) Press the ENTER key. The upper display indicates the
current temperature offset. The current measured temperature is
shown in the lower display.
3) Compare the current measured temperature on the controller
3) Compare the current measured temperature on the controller
display to a thermometer known to be accurate. Note down the
correct temperature value.
4) Press the

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
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
o
C lets you calibrate using standard
buffer solutions at 25
o
C, even if your process temperature is a
different temperature.
1) Select “ATC oFF” as described above in section 7.4.1
