Refer to the electrode instruction manual for how to
adjust the standard solution.
Mix the standard solution at a constant speed (300 – 500
rpm), using a magnetic stirrer. Measure the standard
solution and the sample that is to be measured while
they are at as close to the same temperature as
possible.
4.
Set the standard solution value by using the ▲
or ▼ key to move the value up or down. (The
decimal point can be moved by using the
ENTER key.)
5.
Press the CAL key to start calibration.
The measured value will be displayed, and
"HOLD" will blink until the reading stabilizes. When
the measured value stabilizes, "HOLD" will stop
blinking and the calibrated value will be displayed.
A will appear, indicating that the meter has been
calibrated.
