1 GENERAL
The ionizer has conductive peaks supplied by high
voltage which, based on corona discharge, generate
positively and negatively charged ions in the immediate
vicinity. These are attracted by the electrostatic charge of
goods to be weighed and, thus, neutralise the interfering
electrostatic charge. This also does away with the forces
falsifying the weighing (such as falsified weighing result,
weighing value drifted).
2 Basic Safety Precautions
WARNING
The use of ionizer is only intended in combination with
electronic weighing balances. Do not use for any other
purposes.
Never operate the ionizer in explosive environment. The
serial version is not explosion protected.
Protect the ionizer against high air humidity /
temperature, steams and dust;
Take care to select a location free of water and oil
Do not expose the ionizer to strong humidity for
extended periods. Non-permitted condensation
(condensation of air humidity on the appliance) may
occur if a cold appliance is taken to a considerably
warmer environment. In this case, acclimatize the
disconnected ionizer for ca. 2 hours at room
temperature.
Whilst the ionizer is switched on, do not touch the ion
source; see sticker on the left side.
In case of smoke development, smell of fire, strong
heating-up of the ionizer or when the red LED starts
glowing, turn off the ionizer immediately and disconnect
it from the mains.
If water or other foreign matter enters the ionizer, turn
off the master switch immediately and disconnect it from
the mains.

5 YBI-01-BA-e-0810
On account of the high voltage technology, handle the
ion source and exits with care.
Do not take apart or modify the ionizer.
Prevent damage caused by dropping, vibration or shock;
see sticker on the left side.
Always use the genuine power pack. The stated voltage
value must be the same as the local voltage.
Risk of injury! The peaks of the ion source are sharp
and cutting.
The ionizer generates poisonous ozone; ensure
sufficient ventilation.
For maintenance and repair work disconnect the ionizer
from the mains.
Disconnect the ionizer from the mains during periods of
idleness.

YBI-01-BA-e-0810 6
CAUTION
Maintain and clean the ionizer at regular intervals.
●Clean the ion source after 100 hours.
●Replace the ion source after 10 000 hours.
Starting up a damaged ionizer may result in a short
circuit, fire or electric shock.
Starting up out of doors and inside vehicles is prohibited
and will result in total loss of warranty.
The occurrence of electromagnetic fields may result in
major display deviations (incorrect weighing results).
Discharge sample at a sufficient distance from the
weighing balance.
During normal operation the green LED will be glowing,
in case of a breakdown the red LED.
If the red LED is glowing, turn off the ionizer at the
master switch and turn it on again. If the red LED
continues to glow, inform the manufacturer.
The ionizer may heat up slightly during operation.
Prior to ionising powdery goods to be weighed, turn off
the fan.
Ionisation results are better when the fan is turned on
and the period required for discharging the sample will
be shortened.

5 Unpacking, Setup and Commissioning
Unpacking
Remove device carefully from packaging, remove plastic
wrapping and place device at the planned work place.
Scope of delivery
(1) Ionizer
(2) Frame
(3) Mains adapter
(4) Operating instructions
Placing
The ionizer may be used as a desktop or hand-held
device.
Using it on a desktop
2a
1
2b
Position knob (1) and tighten it by turning.
Insert the ionizer into the V-shaped recess (2a t2b),
ensuring a good fit

9 YBI-01-BA-e-0810
If the device is to be used permanently on a desktop, fix it
with a set screw (3).
3
Use the knob on the frame to set the height and angle of
inclination.
Using it as a hand-held device
To use it as a hand-held device, remove the ionizer from
the frame as illustrated.

YBI-01-BA-e-0810 10
Mains connection
Power is supplied via the external mains adapter. The
stated voltage value must be the same as the local
voltage.
Only use original KERN mains adapters. Using other
makes requires consent by KERN.
Turn off the ionizer (master switch “OFF“) before
connecting it to the mains adapter.
6 Commissioning
Turning on the ionizer
ÖSet master switch to “ON“.
The green LED starts glowing.
During normal operation the green LED will be glowing, in
case of a breakdown the red LED.
If the red LED is glowing, turn off the ionizer at the master
switch and turn it on again. If the red LED continues to
glow, disconnect the device from the mains and contact
the manufacturer.
After use turn off with master switch "OFF".
Turning on the fan
Ionisation results are better when the fan is turned on and
the period required for discharging the sample will be
shortened.
Information:
Turn off fan for powdery, easily whirled up samples.
ÖSet switch of fan to “ON”.
The blue LED starts glowing.
Ensure sufficient ventilation even when the fan is turned
on.

11 YBI-01-BA-e-0810
Applications:
The ionizer is designed to be used in combination with
electronic weighing balances!
Use as desktop device.
ÖDischarge of solids or weighing containers.
Ionisation results are better when the fan is turned
on and the period required for discharging the
sample will be shortened.
Use as desktop device.
ÖDischarge of powdery samples. Discharge
prevents whirling up, problems with toxic samples.
Turn off fan for easily whirled up samples.
Use as hand-held device
inside weighing chamber.
ÖDischarge of goods to be weighed, glass wind
screen or weighing containers.
If your hand is inside the weighing chamber it will
generate heat dissipation. Wait 2-3 minutes before
reading the weighing value.
Use as hand-held device
outside the weighing chamber.
ÖDischarge of beakers etc.
Powdery samples are deposited at the inner wall
of the glass when being poured into the beaker.
This is prevented by discharging the beaker.

Cleaning
WARNING
Disconnect the device from the mains before
cleaning / change of filter.
Do not take apart the ionizer.
Insert only completely dried filters.
Do not use aggressive cleaning agents (solvents etc.)
instead clean with a soft cloth soaked in mild soap
suds. Take care that the device is not penetrated by
fluids and polish it with a dry soft cloth.
Remove loose sample residues / powder carefully with
the help of a brush or hand-held vacuum cleaner.
For cleaning the ion source use a cotton stick
moistened with alcohol; see fig. 1. Take care that the
peaks are not bent.
For cleaning the filter use tweezers to remove it and
clean it with water; see fig. 2 Wait until completely dry
