24. Ionizer
The ionizer removes static electricity by irradiating the target object with positive or negative ions that
are generated from four discharge electrodes by DC corona discharge. Ordinarily, insulators such as
powders, filters, or weighing paper, tend to be charged when the humidity is 45% RH or less, and an
error of a few milligrams may occur during weighing. By removing static from the weighing object with
the ionizer, it is possible to eliminate the error in the weighing value due to charging, and correct
weighing can be performed.
Usage
Step 1.
Make sure that the AC adapter of the balance is not connected, and then connect the balance and
the ionizer (as noted in
Step 2.
Connect the AC adapter, plug it in, and then turn on the power. The power lamp of the ionizer lights
up.
Step 3.
Place the target object within the effective range of static elimination.
Step 4.
Hold your hand over the IR sensor (touchless infrared proximity sensor) on the front of the ionizer
to start static elimination. The ION lamp indicating that static elimination is in progress lights up.
Step 5.
Refer to the figure below for the effective range of static elimination, and perform static elimination.
At factory setting, when three seconds have passed from the start of static elimination, the ION
lamp indicating that static elimination is in progress turns off and static elimination stops.
