Page 3: Equipment Description
Periodic Verification of Air Ionizers and SAE 1645 plus most other specifications requiring a charged plate monitor. The standard Model 204 has a 60 second timer, however, when used to test the dissipation time of automotive fuel system components as specified in SAE J1645 the optional 6 second timer version is required. - Page 4 The 3½-digit LCD meter displays the voltage, polarity, or dissipation time when the decay function of the Analyzer is used. The Model 204 operates from a single 9V alkaline battery with a typical operating life of approximately 20 hours. Low battery is indicated by all decimal points illuminated on the DPM.
- Page 5 This section describes the other functional components included in the Model 216 Kit shown in Figure 2-2. The included tripod is used to hold the Model 204 in either a vertical or horizontal position to facilitate ionizer (horizontal) and charged plate (vertical) measurements.
- Page 6 Model 256 Utility Wiring Verifier This device plugs into a standard (North American) 110 VAC outlet and checks both the wiring of the outlet and provides a convenient standard banana jack output to access electrical ground. This device is not included in kits destined for locations using 220- 240 VAC.

Figure 2-3: Model 5646A Operating Instructions 3.0 OPERATION To use the Model 204 as a charged plate monitor, install the Charged Plate Detector onto the front of the unit. To measure the charge build-up on personnel or moving objects, plug a clip lead, probe or wrist strap into the detector plate. -

Analyzer to ground using the coiled cord provided. To return the Model 204 to the charged plate analyzer function, install the Charged Plate detector by sliding it over the front of the unit and snapping it onto the ¼”... - Page 9 The test set up consists of the Model 204 with the Detector attached. Connect either a wrist strap or a cable with probe. The test subject puts on the wrist strap or grasps the probe. The tripod can be used to hold the instrument.
- Page 10 Another dissipation test is to charge the detector plate and then place a grounded sample on the plate and measure the time for the plate to dissipate its charge through the sample. Charge Neutralization Time This test measures the time for an ionizer to neutralize a charge on an object.

5.0 Calibration The Model 204 is a complex instrument. It is recommended that it be calibrated at the factory. However, the customer can check the voltage reading calibration by applying a known voltage, such as 500 or 1000V directly to the detector plate and compare it with the meter reading. -
