Figure 1. Counter SPI Item 94000
Introduction
The COUNTER SPI is designed to effectively eliminate
localized static charges which exist in the work area.
The Counter SPI is available in two models: Item
94000 is 120 Volt, and item 94001 is 220 Volt. Also
available is item 94002, replacement emitters for the
unit.
HOW TO USE THE COUNTER SPI:
Your COUNTER SPI comes completely balanced and
ready to use.
1. Place your table top unit on a flat, level surface.
2. Plug the COUNTER SPI/WESTEK into any 120V AC
(220V optional) electrical outlet.
3. Turn on/off switch to ON position.
FOR BEST RESULTS:
1. Keep effective area clear and free from obstructions
of ion flow.
2. Position unit so that emitter points are directed
towards area to be ionized.
REMEMBER:
1. Keep work area clear of all static generative
materials.
2. Use only approved static control grounding methods
and material handling equipment.
3. By properly using ionized air, all static potentials in
the work area are greatly reduced, even when
humidity levels decrease.
CAUTION: Care should be exercised during handling
to prevent the unit from falling face down. The delicate
emitter pins will be damaged or broken if this happens.
CLEANING INSTRUCTIONS:
Your Ionizer was designed to be virtually maintenance
free. The emitter points can be cleaned when there is
a visible accumulation of dirt. Generally this would be
twice a year, depending on the cleanliness level of the
working environment.
1. Check the emitter points for dirt accumulation.
2. Be sure the unit is unplugged.
3. Wipe emitter point with a swab dampened in
isopropyl alcohol.
4. The outside case may be wiped down with a soft
damp cloth.
CALIBRATION AND BALANCE VERIFICATION:
The COUNTER SPI is factory set to achieve a
maximum balanced ion output in standard, non-air
assisted applications. To certify calibration, we
recommend EOS/ESD association standard
"EOS/ESD-3.1-1991."
Objective: To observe, test and record performance
levels of ionization units, utilizing readily available
equipment, thereby verifying or certifying calibration.
Equipment Used:
Charged Plate Analyzer (Item 94052)
Procedure:
1. Position the COUNTER SPI 12 inches away from
the 94052 directly facing the unit.
2. With the COUNTER SPI and the 94052 on, adjust
the balance trim pot, located on the lower left side
of the 94000. Balance the 94000 to zero on the
94052. NOTE: there are 3 LEDs located on the
front panel. The one on the left is the on light, the

other two LEDs are the indicators of the positive and
negative. Note the rate in which the lights switch.
Your unit should be set at a slow rate. Also note
when balancing, the indicator lights, as you offset
the positive and the negative (balance), the on and
off times changes on the lights.
3. Charge the 94052 to 1KV of either polarity ± and
push the decay button. The timer will automatically
time the decay rate. The typical decay is 1,000 to
100 volts in under 60 seconds of both polarities.
There are two adjustments that can be made on the
COUNTER SPI: the BALANCE and the RATE. The
BALANCE of positive and negative ion output can be
adjusted to increase polarity bias by inserting a small
screwdriver through the BALANCE port and slowly
turning the trimpot CLOCKWISE to increase positive
and decrease negative ON time pulses OR COUNTER
CLOCKWISE to increase negative and decrease
positive ON time pulses. The RATE or pulse frequency
can be adjusted down to one pulse per second or up to
5 pulses per second by inserting a small screwdriver
through the RATE port and slowly turning the trimpot
clockwise to increase and counterclockwise to
decrease the frequency.
REMEMBER:
It is important to verify calibration after any adjustments
and before using your COUNTER SPI around sensitive
electronics. Merely repeat above Balance Verification
steps after all adjustments.
Field repairs are not normally encouraged during the
warranty period. Repair attempts by unqualified
personnel may invalidate the warranty.
IMPORTANT:
Your COUNTER SPI ionizer has been designed to
minimize effects of localized charges. If your
processing involves generation of considerable static
charges you may need more aggressive equipment.
SPI has available a complete line of Ionizing Blowers,
Air Guns, Bars and Overhead Room systems to meet
all ionizing requirements.
