Conductivity measurement

Place the conductivity sensor in the sample and press
point flashes.
The display shows the conductivity of the sample. The automatic endpoint A is the meter's default setting.
When the sensor output has stabilized, the display freezes automatically, and
The automatic endpoint algorithm is as follows: The measured conductivity of the sample may not deviate
by more than 0.4% from the measured average conductivity of the probe of over 6 seconds.
By pressing and holding the
manually endpoint a measurement, press

TDS/salinity/resistivity measurement

To perform a TDS/salinity/resistivity measurement, follow the same procedure as for a conductivity
measurement. Press the

5.3.1 ATC/MTC
Most conductivity sensors have a built-in temperature probe. When a temperature probe is used, the
symbol ATC and the sample temperature are displayed.
When the meter does not detect a temperature probe, it automatically switches to manual temperature
compensation mode, and MTC appears.
To set the MTC temperature, see 5.3.2 Menu setting.
