Measurement Using a Calibration Curve
The Ion electrodes and the reference electrodes cause gap in the output according to the tem-
perature change. Although this meter features the temperature compensation function, adjust
the solution temperature of the measurement and the calibration as same as possible.
When the Ion electrodes and the Conductivity electrodes are connected to perform 2CH
simultaneous measurement for the same solution, it may take approximately 10 seconds until
the indication stabilizes.
5.2.1 Calibration Using Ion Standard Solution
●
CH 1 calibration
1.
In any Measurement screen of the
channel (CH) corresponding to the
Ion measurement, press the
MODE key.
ION Measurement screen appears.
2.
Press the CAL key.
The ION CAL. screen appears.
3.
Wash the tip of the electrode well
with pure (de-ionized) water, then
blot with filter or tissue paper.
4.
Open the internal solution filler
port.
During the calibration, the filler port
should be kept open.
Filler port may differ in the structure depend-
ing on the electrode.
