 Model 268A-1 Charge Plate Monitor
Provides quick and easy evaluation of ionization equipment to ESD Association
Standard No. 3 The simple-to-use unit features two modes of operation. The normal mode evaluates the effectiveness of room ionization, laminar flow hoods,
table top ionization and air guns and nozzles as described in the ESD Association standard, including static decay timing and system balance
monitoring. The peak mode reads and holds either the positive or negative peak reading on the charged plate. This is useful for monitoring maximum DC voltage
swings in pulsed DC ionization systems. The Model 268A-1 features two switch-selectable ranges 0 to ±2,000 V or 0 to ±5,000 V with automatically set trip
points to begin and end static decay tests. The isolated charge plate/probe assembly is removable and is fitted with a tripod mount for easy positioning.
