5) Compare the current measured temperature on the controller display

to a thermometer known to be accurate. Note down the correct

temperature.

6) 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 ºC.

7) Press the ENTER key to confirm your selection.

Measurement mode by pressing the ▲ and ▼ keys (escape) simultaneously).

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.

6) After you set the process temperature value, press the ENTER key. The upper display shows the

current calibration temperature and the lower display shows “C.ºC” to indicate calibration

temperature.

7) Press the ▲ or ▼ keys to adjust the calibration temperature value. You can adjust the value

from -9.9 to 125 ºC.
