Conductivity/TDS/Resistivity Measurement
1.
Press the
Mode
key until the meter shows
(Conductivity) or
(TDS) or
(Resistivity) icon.
2.
Rinse the conductivity electrode thoroughly with distilled water.
3.
Place the electrode into the sample solution, stir the electrode gently.
4.
Record the measured value when the reading is stable.
Salinity Measurement
The meter provides two salinity measurement modes - practical salinity (unit: PSU) and natural seawater (unit: ppt).
1.
Press the
Mode
key until the display shows
icon
and measurement unit “PSU”, the meter enters
the practical salinity measurement mode.
2.
If necessary, press the
Mode
key again, the meter shows
icon
and measurement unit “ppt”, the meter enters
the seawater measurement
mode.
3.
Select the desired measurement mode. Place the electrode into the sample solution, stir the electrode gently.
4.
Record the measured value when the reading is stable.
Dissolved Oxygen Measurement
The meter is suitable for measuring the water, wastewater, brine and other liquids. If the sample is belong to the seawater or other water containing large
amounts of salt, please setting the salinity coefficient before measurement. Some gas and steam such as chloride, sulfur dioxide, sulfureted hydrogen,
ammonium, carbon dioxide and iodin can permeate the membrane via diffusion. So their existence will influence the measurement of dissolved oxygen. If
the sample contains the solvent, grease, sulfide and alga, the membrane on the probe will be blocked, damaged or eroded.
Setting the barometric pressure
The following table describes the relationship between altitude and barometric pressure. Prior to the calibration or measurement, you need to set the
compatible parameter according to the local altitude.
