The internal charging source of the Model 204 is a miniature, dual polarity 1200 Volt power supply that charges the isolated detector plate when either the + or ” CHARGE button is depressed. The charging function automatically activates the timing mode. As the applied 1200 Volt charge on the detector plate decays, either by ionization or by dissipation through a resistance, the timer starts counting when the measured voltage decays below 1000 volts and stops when it reaches 100 Volts. Decay times up to 60 seconds in 0.3 second increments can be measured in the standard version and up to 6 seconds in 0.03 second increments in the J1645 version.
The Model 216 consists of the Model 204 Charge Plate Analyzer with a 20pf (1″ x 3″) charged plate detector, plug-in 6″ x 6″ detector plate, tripod, utility wiring verifier with ground jack plus a Humidity/Temp/ Dew Point Indicator.
The 3½-digit LCD meter displays voltage (1 volt resolution), polarity, low battery warning, plus dissipation time when the decay function of the analyzer is used. When the Charge Plate Detector is removed, the Model 204 converts to a standard 20kV static meter with 10 volt resollution.
