programming options. Can be preset to
perform a number of automated tests and
is available to store or retrieve previously
defined test parameters. Test locations
and results can be saved and retrieved
for future reference.
Ion Collecting Plate
(standard option)
Meets ANSI/ESD-STM3.1 requirements
Power ON-OFF A momentary push-button
Float Mode, (+) Decay
Mode, or (-) Decay Mode
Performs float voltage and decay time
EOS/ESD measurements utilizing
parameters, guidelines, and standards
set by the EOS/ESD Association
Features (cont.)
For (+) Decay and
(-) Decay Modes The charged-plate is charged to a voltage
level above the programmed (+) or (-) start
voltage value. The plate is allowed to decay
toward zero due to the ion impingement on
the plate. The time required for the plate to
decay from the programed start voltage to the
programed stop voltage is displayed on the
timer.
For Float Mode The charged-plate monitor is reset to 0 V ±0.5
V. The plate is allowed to “float” to a voltage
level dictated by ion impingement on the plate.
USB Flash Drive
USB Host USB host port allows information to be saved,
retrieved and exchanged.
