Power should be applied to the Condensation Particle Counter
(CPC) and the Electrostatic Classifier. The analog output must be
set to HOST in the Model 3010, 3022A, or 3025A CPC. See
“Applying Power Sequence
” in Chapter 3 for more information. On
the Classifier, the voltage control should be set to “Analog Ctrl”
(lower left pane on display—see Figure 4-1) to allow the DMA
voltage to be controlled by the CPC.
