Instructions for the Ion Picoamp Meter

This Ion meter is used for the measurement of ions that come from an ionizer. The detector will show you whether ions are reaching into all corners of the room. Usually the ions that come from an ionizer are the good (negative ions) kind, and these negative ions display on the detector with a "-" sign.

To use the detector, you should plug the earth (ground) wire (7 meters long) into the right side of the meter. Then connect the clip (on the other side of the earth wire) to something that is at earth ground voltage, which means to metal plumbing or a sink, or to the screw from a wall plate for a light or wall socket (mains), though if you use this screw, you should unscrew it a little so the clip will stay on it. Any other earth ground metal is good, too. If you are very experienced with earthing, you can connect it to earth without the earth wire: just hold the case of the detector and then you should touch something earthed, every few minutes.

You will see a special plastic "plate" in the top of the meter. This top plate is about 6.5 x 2 cm and it is not quite shaped like a perfect rectangle. It is a slightly different color of black compared to the other parts of the black case. This top plate should be pointed toward the ionizer when you make a measurement. You should avoid holding your fingers over this top plate, since that will block some of the ions.

Turn the detector on.

When you measure, the detector will read in "picoamps". This is one millionth of one millionth of an amp. One picoamp means that 6 million ions are hitting the top plate every second. Please stand still and hold the detector still for a few seconds to make a measurement. If the detector reads more than ± 10 picoamps at a distance of two meters from the ionizer, then the reading indicates a good distribution of ions. If the detector reads less than ±10 at 2 meters away from the ionizer, then you should use a fan to blow ions away from the ionizer (and toward you), until it measures more than 10, then you will have a good distribution of ions in the room.

Sometimes the needle on electric ionizers will become dirty. The dirt (or dust) will cause the output to be much less. It you measure the typical number of picoamps at a distance of (for example) 1 meter, you might see that number is much less at a later time. Then you should clean the needle, after turning off the ionizer, according to the ionizer instructions. After cleaning, the reading should increase back to the usual number of ions.

If all three decimals are displayed ( . . . ), the battery is low. Slide the back door off and replace the weak 9-Volt battery with a new standard 9-volt battery.
