1. GENERAL INFORMATION
Antistatic ionizer is a device that removes excess of ions, both positive (cations) and
negative (anions), from the sample, weighing device's components and the environment.
Ionization is an operation aiming to neutralize electric charge of air molecules in order to
restore quasi-balance of positive and negative ions.
Imbalance of cations and anions in the air causes unwanted electric interaction (attraction
and repulsion) between objects located close one to another. This process is even more
intense in case of non-conductive materials (plastic, glass). When it comes to the weighing
device, its operation is affected by the said interactions due to the fact that some of the
device components are made of the said non-conductive materials.
Affected operation as a results gives greater repeatability error, often also greater error of
indication.

3. BASIC SAFETY PRECAUTIONS
WARNING
Air ionizer must be operated as an accessory of electronic balances,
exclusively. The ionizer cannot be used with other devices.
Under no circumstances should the ionizer be used in a hazardous area
where there is any risk of explosion. The air ionizer is not intended to be
operated in EX zones.
Ionizer must work in an environment where it is not exposed to:
•
high air humidity (humidity range guaranteeing correct operation is 10
÷ 80 %),
•corrosive fumes,
•
high temperature (temperature range guaranteeing correct operation
is 0 ÷ 40 °C),
•vibrations or heavy shocks.
Make sure that at the i
onizer's workplace there is no water or oil. Due to
the fact that in the course of ionizer's operation ozone is produced, the
workroom where the ionizer is operated must be equipped with a valid air
conditioning system.
If the ionizer had been stored in a
place where the temperature is much
lower than the temperature of the workroom, prior running the ionizer, it
is necessary to let its temperature stabilize -
leave the ionizer in the
workroom for about 2 hours.
Otherwise humidity condensation may occur, wh
ich in turn may result
with an electrocution.
Do not touch ions source, this may cause either electric shock (in the
course of operation) or injury (components generating ions are sharp).
Should you notice any signs of incorrect operation (smoke, burnt material
smell, irregular ionizer warming), disconnect the device from the power
supply immediately. Should water or any foreign bodies get inside the
ionizer, behave likewise, i.e. disconnect the ionizer from the power
supply immediately.

6
Due to high voltage, typical for the ionizer, remain extremely careful
while operating it.
You are not allowed to either disassemble or modify the ionizer. Use
the device only as intended.
The ionizer must be connected to the mains only by means of an
original power cord which comes standard with it. Rated voltage
(specified on the device’s data plate) must be compatible with the
mains rated voltage.
The power cord can be connected only to a socket with a ground
contact.
The ionizer w
hen not operated must be disconnected from the
mains.
Any repairs to be done must be carried out by service authorized by RADWAG.
CAUTION
It is forbidden to connect ionizer that is broken to the mains – this
may result with either electrocution or fire.
It is not allowed to use ionizer outdoors or in vehicles, this will result
with loss of warranty.
Be aware of the fact that the device in the course of regular operation
may get warm.

4. MECHANICAL DESIGN OF DJ-04 and DJ-05 IONIZERS
The ionizer comprises two modules (see the figure below) and power supply:
1 – ionizing unit,
2 – high-voltage generator,
3 – power supply.
5. UNPACKING
5.1.Unpacking
Unpack the device, remove protective foam, next carefully remove the antistatic ionizer
from the box and place it at its workstation.
6. START-UP
The ionizer must be connected to the mains by means of power supply that comes
standard with it. Ionizer activation is signalled with diode placed on the housing, when the
ionizer is on the diode emits light
6.1.Operation
Ionizer operates with positive and negative polarization in turns. This enables effective
removal of electric charges regardless of the sign.

7. MAINTENANCE, SERVICE, RECYCLING
Any maintenance activities (cleaning) must be performed 5 minutes after disconnection of the
device from the power supply.
7.1.Maintenance
Power supply housing and ionizing unit can be cleaned using cloth soaked with alcohol-
based substance.
7.2.Service
Only authorized RADWAG service points are allowed to disassembly, repair and modify
the ionizer.
It is recommended to:
•subject the ionizer to technical inspection after 500 hours of operation,
•replace ions source after 10 000 hours of operation.
7.3.Recycling
The device and the packaging must be recycled in accordance with valid state
regulations.
