Ionization Test Kit
Operation and Maintenance
Description
The Desco Ionization Test Kit allows the 19492 Digital
Static Field Meter to be used to measure the offset
voltage (balance) and charge decay of ionization
equipment. The Test Kit also includes a Charger used to
place a ±1000V charge on the 19498 Conductive Plate,
making it possible to also measure the discharge times
of air ionization equipment per ANSI/ESD SP3.3 Periodic
Verification of Air Ionizers. The 19493 Ionization Test Kit
includes the 19492 Digital Static Field Meter, providing a
highly portable and cost effective means of verifying the
performance of a wide variety of ionization equipment.
Note: The 19492 Digital Static Field Meter is designed to
operate only with the 19493 Ionization Test Kit. It is not
compatible with other brands.
Although not as accurate, the Desco Ionization Test Kit
has been designed to make measurements that
correspond to those made by using a charged plate
analyzer and ANSI/ESD S3.1. The Ionization Test Kit
provides convenience and portability to test per ANSI/
ESD SP3.3 Periodic Verification of Air Ionizers or
Compliance Verification ESD TR53. We recommend
measurements are required.
The Ionization Test Kit includes a slide-on isolated
Conductive Plate, a ±1000 volt Charger and a durable
thermoplastic carrying case with custom cut-outs for all
of the above components along with the model 19492
Digital Static Field Meter.
Charged insulators in the ESD protected area can
adversely impact quality, productivity, and reliability.
“When any object becomes electrostatically charged,
there is an electrostatic field associated with that charge.
If an ESDS (ESD sensitive) device is placed in that
electrostatic field, a voltage may be induced on the
device. If the device is then momentarily grounded, a
transfer of charge from the device occurs as a CDM
(Charged Device Model) event. If the device is removed
from the region of the electrostatic field and grounded
again, a second CDM event will occur as charge (of
opposite polarity from the first event) is transferred from
the device.” (ESD Handbook ESD TR20.20 section
2.7.5 Field Induced Discharges)
Compliance verification should include periodic checks
with a static field meter to determine if high
charging material is present in the ESD protected area.
All packaging and other materials that may be
electrostatic generative to 2,000 volts must be kept a
minimum of 12" from ESD sensitive items at all times. It
is proper to rub an item and measure that it can charge.
“In order to mitigate field-induced CDM (Charged Device
Model) damage, the ESD program shall include a plan
for the handling of process-required insulators. If the
field exceeds 2,000 volts/inch, steps shall be taken to
either:
A. Separate the insulator from the ESD-sensitive device
by a distance of 30 cm (12 inches); or
B. Use ionization or other charge mitigating techniques
to neutralize the charge.” (ANSI/ESDS20.20 section
8.3)
Other steps that can be taken are to remove the item
from the ESD protected area, periodically coat with a
topical antistat, or replace with a static control protective
version of the item.
