Charge Plate yzer 268A
Featur:
• Easit, most reliable way to check
effectivens of all ionization-te
static control systems
• Meets D ociation Standard No.3
• Removable, cable-connected plate/
probe permits precise positioning and
remote monitoring
• Separate time and voltage displays for
decay rate ysis
• Recorder output for permanent
records and unattended operation
• Two rang measure from 0 to &plun;5kV
• Dramatically demonstrat induced
charg and human body potential
Make sure antistatic devic are working
Wrist straps, work surfac, 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 tt parameters
(mode, polarity, voltage range, and upper and lower
voltage limits across which the decay rate is to be
measured.
3. Prs ZERO to ground the plate, then prs
CHARGE to bring the plate to the prelected
maximum voltage.
4. Prs DECAY, as the ionization system
neutraliz 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 s
voltage at any level from 0 V to 1000 V. The start
voltag remain the same.
Evaluate all ionization systems and
anti-static devic – and demonstrate
charge prence
Two operating mod cover all t of ionization
systems.
For room and table- ionization systems,
laminar flow hoods, and air guns and nozzl the
normal (discharge) mode provid 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.
