2.2 Sample measurement
Place the electrode in the sample solution and press the "Read" button to start the
measurement, and the decimal point on the screen flashes. The automatic
measurement end point (with the A icon display) is the default setting for the
meter. When the result is stable, the decimal point is no longer flashing, and there
is a display on the screen.
Press and hold the "Read" button to switch between automatic and manual
measurement end mode. To manually measure an end point, press the "Read" key
to display the value.
To view the mV value during the pH measurement, simply press the "Mode"
button to execute the mV (ORP) measurement, according to the same steps as the
pH measurement.
2.3 Temperature measurement
To improve accuracy, we recommend using a temperature probe or an electrode
with a built-in temperature sensor. When using the temperature electrode, the
screen displays the ATC symbol and the sample temperature.
