Description
Our Portable Ionization Test Kit is a
portable and cost effective means of
verifying the performance of a wide
variety of ionization equipment. The
Test Kit includes a 42721 Digital
Fieldmeter, an Isolated Plate
Assembly, and a Charger. The
Charger is used to place a 1000V
charge on the isolated adapter plate
assembly, making it possible to also
measure the neutralization
performance of air ionization
equipment.
NOTE:
Our 42721 Digital
Fieldmeter is designed to operate
with our 42755 Portable Ionization
Test Kit. It is not compatible with
other brands.
Currently there are no established
standards describing a periodic
verification device or procedure for
air ionizers. The ESD Systems.com
Portable Ionization Test Kit has been
designed to make measurements that
correspond to those made by using a
charged plate analyzer and ESD
Association's Standard 3.1. While
the Ionization Test Kit provides
convenience and portability, it does
not meet all of the requirements of
the ESD Association Standard. ESD
Systems.com recommends our
model 42630 Charged Plate
Analyzer if precise measurements
are required.
The Portable Ionization Test Kit
includes a slide-on isolated plate
assembly, a ±1000 volt charging unit
and a durable thermoplastic carrying
case with custom cut-outs for all of
the above components along with
the model 42721 fieldmeter. The
42721 Digital Fieldmeter can be
purchased separately.
Inspection
Remove the kit from the carton and
inspect for damage. Each kit
includes:
1 Digital Fieldmeter (Item 42721)
1 Isolated Plate Assembly
1 ± 1000 Volt Charger
1 9 Volt alkaline battery (installed)
1 Carrying case
Taking Balance
Measurements
The Portable Ionization Test Kit has
been designed to match the compact
size and hand held convenience of
the 42721 Digital Fieldmeter. Use
the following procedure to verify the
balance of air ionization equipment.
This quick and easy procedure will
indicate if the piece of ionization
equipment is working within the
manufacturer's specifications or user
requirements.
It is extremely
important that ionizers be checked
regularly for balance. An ionizer
operating in an out-of-balance state
can damage sensitive electronic
components or assemblies.
1. INSTALLING THE ISOLATED
PLATE ASSEMBLY -
The case of
the Model 42721 Fieldmeter has two
slots along its slides. The top slot is
closest to the front of the instrument.
Slide the tabs of the Isolated Plate
Assembly into the top slot of the
meter case as far as they go.
