How much water should I use on the Sensors?

How much water to be used on the sensors may vary depending on hair thickness and texture. In general, it is always best to start with using 3 droplets of water and only adding more if needed. If you find that you need to use more than 3 droplets on each sensor, there will be no issue. Do keep in mind, however, that too much water may cause challenges with getting a signal check.   

Be sure to only dampen the sensors from the top and to brush individual droplets into the sensors (i.e. add one drop, brush it in, add the second drop, brush it in etc.)

It is also important to mention that only tap water or spring water is used when dampening the sensors.  Using water that is distilled or has gone through reverse osmosis will impact signal check quality as they lack the necessary minerals needed for conductivity.
