Temperature Calibration - Thermo Scientific Eutech EC 1720 User Manual

4.4 Temperature
Calibration
The thermistor sensor used for automatic temperature
compensation and measurement is both accurate and
stable, so frequent calibration is not required.
When conductivity electrode with built-in ATC sensor is
connected to the meter, use the Temperature Calibration
item within the Setup Menu to perform a one-point offset
calibration, up to ±5.0 °C.
Place the ATC probe into a solution with a stable
temperature and NIST traceable thermometer.
Press the "Menu" key to enter the Setup Menu.
Press the  or  key to scroll through the Setup
Menu list until the Temp. Calibration item is shown.
The temperature value will blink, indicating the
reading from the ATC probe is being measured.
Once the reading is stable, the value will stop
blinking and the checkmark icon will be shown.
Press the  or  key to adjust the temperature
value. The temperature offset value will be shown in
the 2 nd field.
a. Press the  key to increase the value by 0.1°.
Press and hold the  key to quickly increase.
b. Press the  key to decrease the value by 0.1°.
Press and hold the  key to quickly decrease.
Press the "Enter" key to save the change.
Note: Press the "Measure" key at any time to abort the
calibration and return to the main measure mode.
