Each meter is supplied in a rugged plastic carrying case with 4-ring conductivity probe, calibration solution bottle (120 mL), screwdriver and instructions.
Operations: • Connect the conductivity probe to the meter (Fig. 1) and turn the unit on by sliding the ON/OFF switch on the top of the instrument.
• Dip the probe into the solution by ensuring that all 4 rings of the probe are immersed and without exceeding the maximum level (Fig. 2).
• Stir gently to remove any air bubbles trapped inside the probe and wait for the reading to stabilize.
• To minimize errors, it is recommended to rinse the probe with some of the sample to be tested before taking measurement.
• After use, switch the unit off, rinse the probe in alcohol for a few minutes.
• If the display fades, replace the batteries. Switch the unit off, pull out the battery compartment and replace the batteries (Fig. 3).
Battery replacement must only take place in a non hazardous area using the battery type specified in this instruction manual.
Calibration: • Dip the probe into the proper (supplied) calibration solution and wait for the reading to stabilize.
• If necessary, correct the reading to the solution value by slowly turning the calibration trimmer with the supplied screwdriver.
