Charge Plate Analyzer 268A
Features:
• Easiest, most reliable way to check
effectiveness of all ionization-type
static control systems
• Meets ESD Association Standard No.3
• Removable, cable-connected plate/
probe permits precise positioning and
remote monitoring
• Separate time and voltage displays for
decay rate analysis
• Recorder output for permanent
records and unattended operation
• Two ranges measure from 0 to ±5kV
• Dramatically demonstrates induced
charges and human body potential
Make sure antistatic devices are working
Wrist straps, work surfaces, flooring materials —
static decay measurement is a sure indication that
they’re doing their job. The plate has a connector to
permit measurement of charge buildup on operators.
Easy to use
To operate in discharge mode:
1. Locate the removable plate/probe where
ionization is to be checked, main instrument
where convenient.
2. Turn the instrument on and select test parameters
（mode, polarity, voltage range, and upper and lower
voltage limits across which the decay rate is to be
measured.
3. Press ZERO to ground the plate, then press
CHARGE to bring the plate to the preselected
maximum voltage.
4. Press DECAY, as the ionization system
neutralizes the plate charge, the instrument will
continuously measure the decaying voltage.
Elapsed time （in seconds） is displayed on the front
panel, along with plate voltage. The speed at which
the voltage drops is proportional to ionization
system performance.
Measurement in the peak mode is just as simple.
Model 268A-1T adjustable timer option
This option allows the user to set the timer stop
voltage at any level from 0 V to 1000 V. The start
voltages remain the same.
Evaluate all ionization systems and
anti-static devices – and demonstrate
charge presence
Two operating modes cover all types of ionization
systems.
For room and table-top ionization systems,
laminar flow hoods, and air guns and nozzles the
normal （discharge） mode provides both static decay
timing and system balance monitoring.
For pulsed DC ionization systems the peak
mode monitors voltage swings by reading and holding
the peak voltage and polarity （positive or negative）
sensed on the charged plate/potential.
