2-2 Model 3022A Condensation Particle Counter
Initial Setup
This section contains instructions for initial setup of the
Model 3022A CPC. Follow the instructions in the order given.
Protective Caps
Remove all protective caps from the inlet and exit flow ports, as well
as from the BNC
connectors.
Checking the Line Voltage Configuration
The Model 3022A requires 100/120 volts AC at 1.2 amps or
230/240 volts AC at 0.6 amp with 50 to 60 hertz at any of the
voltages. Use the information in this section to verify the line
voltage configuration and fusing arrangement matches your local
line voltages.
Check the back panel of the instrument for the voltage and fusing
requirements. The label is located just above the power entry
module.
To change the voltage setting, follow these steps:
1. Disconnect the power from the Model 3022A
and remove the
line cord. Locate the power-entry module on the back panel of
the Model 3022A (Figure 2-1).
*
2. Lift off the cover of the fuse and voltage module cover on the
back panel of the Model 3022A using a small-blade screwdriver
or similar tool (Figure 2-1). Set aside the cover/fuse block
assembly.
