3.0 OPERATION

3.1 Initial Set Up
1. Before connecting the Static Decay Meter to the AC line, the four cables from
the Faraday Cage must be connected to the Control Unit as shown in Figure
3.1-1.

2. Recheck all cable connections to make sure that they are tight. Set the
following controls to the positions indicated:
3. Connect the Control Unit to the AC line by plugging its AC cord into a
properly grounded AC outlet (Mains).
4. Lift the hinged cover of the Faraday Cage and place the STM Module
between the electrodes of the sample holder as shown in Figure 3.1-2.
Return the cover to its operate position (cover down). [Note: If using an
The System Test Module (STM-1) supplied with each Model 406D Static
Decay Meter prior to Serial # 877 enables the user to check its operation
against a stable, repeatable standard. The STM-1 uses electronic
components (resistors and capacitors) to simulate a test sample with a
known and repeatable decay time that is relatively independent of room
temperature and moisture conditions. When using the STM-1 the FULL
SCALE ADJUST control must be set to the STM-1 position to achieve a
full scale reading on the SAMPLE CHARGE meter and then returned to
the NORM setting to test samples.
