5.1 Taking pH Measurements
5.1.1 Automatic Temperature Compensation
Automatic Temperature Compensation only occurs when a
temperature sensing element is plugged into the meter.
Temperature sensing element refers to the following probes
made specifically for this meter:
•
The conductivity electrode (EC-CONSEN91W/
35608-50) with a built-in temperature sensor;
• Temperature probe (EC-PHWPTEMP-01W/
35618-05); or
• The “3-in-1” pH/Temperature combination
electrode (EC-FE73528-01W/ 35808-71).
If there is no temperature sensor plugged into the meter, the default manual temperature
setting is automatically 25 °C. You can manually set the temperature to match your working
conditions using a separate thermometer.
For automatic temperature compensation (ATC) simply plug the temperature probe into the
meter (see page 6 for directions). The ATC indicator will light up on the LCD. See figure 12.
NOTE: The temperature sensing element must be submersed in the liquid you are
measuring.
