Are you using a microsiemens conductivity meter with fresh battery? Not a TDS meter. Did you clean electrodes with fine steel wool before the session? Has there been any change in the water you are using? If the water is too pure, there will be very little electrical current flowing between the electrodes. This is why I have raised the applied voltage to 100v and introduced the new digital display of current.
Conductivity meters do not indicate accurately with metals other than silver particularly with Gold and Platinum.
Turn on the generator with the control knob and observe the ON/OFF light. To test for proper functioning, take generator out of the water, plug in the two electrodes, then short the two electrodes together to make full current-limited power to flow from the generator. The meter should indicate current flow. Alternatively using a multimeter in the voltage mode measure that the output voltage between the two electrodes is around 100 volts. This voltage will change as current adjusts in the water. It is current which does the charging. Then turn the multimeter to the 200 mA position, connect the multimeter to the two electrodes, and measure the current flowing between the two electrodes . At the low settings of the nanometer control knob, you should be seeing a reading of 6 to 20 mA. Make sure that the water you are using is not too pure or not conductive enough. Distilled or deionised water will at first not conduct enough electricity, until sufficient atoms have entered the water.
If the lights of the generator do not come on, then there may not be power coming in to or from the 12 volt wall adapter. Due to our constant current feature, you can safely short the two electrodes to each other to make sure that current is flowing. All LEDs are merely indicators and not essential to the functioning of the generator. Sometimes the LED may burn out if there has been a lightning surge at your location. This will not affect the process.
PPM measurement: Even among experts there is confusion about ppm and how much is Ionic and how much particulate (colloidal) and how our conductivity meters and even analytical laboratories inaccurately reflect these measurements. Regarding the water test meter, it measures only electrical Conductivity of the water which is only an indirect measure of charged ions and atoms in the water and is the best method conveniently available. TDS (Total Dissolver Solids) is a measurement of Sodium Chloride not nanoparticles which are usually negatively charged, thus confusing the measurement. Don’t use a TDS meter, use a proper micro-siemens conductivity meter which we sell for $140. Even so, taste is the best indicator of ppm.
With distilled water the measurement usually commences at zero or 1 and slowly rises to about 25 microSiemens after 24 hours with Silver. Reverse Osmosis water starts around 5-10 microSiemens and goes up to 50 -60. An accurate measure of parts per million can only be done by sending a sample of the water to a special analytical laboratory, which we have done several times and correlated the ppm result with conductivity. However even professional laboratories give us conflicting, inconsistent reports. Taste is best.
