Temperature Calibration (ATC mode only)

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 "on ATC". Press ENTER key.
4) The upper display indicates the current temperature offset. The current
measured temperature is shown in the lower display.
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.
8) Continue with additional Advanced Set-up procedures, or return to the
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.
Press the ▲ or ▼ keys to select "oFF ATC". Press ENTER key.
3)
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.
