Conductivity Calibration

● Conductivity Calibration
Calibration is necessary for accurate electrical conductivity measurement. To perform
conductivity calibration, follow the procedure detailed below:
Prerequisites
• Clean the conductivity electrode with DI (deionized) water and wipe it with tissue paper.
• Switch on the meter and plug in the conductivity electrode.
• Prepare standard solution required for calibration.
• Press the
key to keep the meter in COND mode.
• Dip the conductivity electrode in the standard solution until the hole at the upper part of the
electrode is immersed.
• Salinity, TDS, and resistivity of a sample solution are calculated from the measured value
of conductivity.
• In conductivity calibration mode, the default calibration method is auto calibration. If you
like to change it to manual calibration method, refer “P1.3 Calibration Mode Setup” on
page 32.
• For second or multiple point calibration, clean the conductivity electrode with DI water and
follow the same procedure.
• If you are performing multiple point calibration, calibrate to the lowest conductivity first and
then move to increasing conductivity values. This minimizes cross contamination.
• To abort an ongoing calibration process at any point of time, press the key.
