Measurement Procedure
Sample Preparation:
1. For Conductivity, TDS or Salinity place the test sample in
a sample cup with enough depth (2.5cm minimum) to
cover the electrode. Stir the solution to remove any air
bubbles.
2. For pH, place the tip of the electrode in the sample or
make contact with a wet surface.
Measurement:
1. Press the ON button. ( and then “SELF CAL” will
appear in the display during the turn-on diagnostics)
2. Depress and hold the MODE/HOLD key to scroll to the desired
measurement mode.
3. Insert the electrode into the sample making sure that the
electrodes are completely submersed.
4. Slowly stir the solution with the electrode to remove air bubbles
if in the Conductivity, TDS or Salinity mode.
5. If in the Conductivity, TDS or Salinity modes, the meter will
auto-range to the proper range and then display the reading.
