 3.7 Balance Adjustment and System 

Calibration

Simco-Ion balance adjustment and calibration procedure is a 
regular part of installation and maintenance of the AeroBar and its 
components. Adjustment for the AeroBar may be performed at 
initial installation, during periodic checks of the entire system, or 
anytime additional components are added to the system. 

This section consists of the following information:

• About Adjustment and Calibration
• Tool parameters that Affect Ionization
• Performing the Adjustment
• Understanding Ionization Modes, Voltage Swing and Output, 

and Decay Timing

• Troubleshooting

Goals of Balance Adjustment and System Calibration

• Balanced, high ion density arriving to the surfaces and wafers
• Similar positive and negative decay times
• Maximum decay in the amount of available time
• Moderate voltage swings (Pulsed DC) or voltage offset (Steady-

state DC) to eliminate the possibility of inducing voltage on the 
surfaces

Recommended Equipment

• Charge Plate Monitor Model 280A
• Tripod (optional)
• Anemometer

About Adjustment and Calibration

Environment variables and the physical properties of ions can lead 
to degraded ionization performance over time. This leads to a 
greater risk of static or the presence of voltage on your sensitive 
product surface.
