To Use the AD-1683 Safely
Thank you for your purchasing the AD-1683 DC static eliminator.
Please read this manual completely before using the AD-1683.
Warning Definition
The warning described in this manual has the following meaning:
Important information to alert you to a situation
Caution
that may cause injury and/or damage to your
property if instructions are not followed.
When operating this instrument, be sure to observe the
following safety precautions
Caution
Do not open the case to repair the AD-1683. Only qualified
personnel can do that. Attempting repairs yourself may cause
damage to the AD-1683. Damage caused by attempting to do
the repair yourself will void the warranty.
Do not use the AD-1683 in a closed environment. Ozone
that is harmful to the human body may stray into the air.
Ventilate well.
The AD-1683 is not explosion-protected. Do not use the
instrument where flammable solvents or dust exits.
Do not touch the discharge electrode pins. It may cause an
electrical shock.
Use the specified AC adapter only. Please confirm that the
AC adapter type is correct for your local voltage and
receptacle type. If an AC adapter other than specified is
used, static electricity may not be eliminated or it may
cause an electrical shock. (*1)
Be sure to insert the AC adapter into a grounding-type
electrical outlet and earth ground the grounding cable.
Otherwise, static electricity may not be eliminated or it may
cause an electrical shock.
*1: Use the AC adapter identification label to identify the AC adapter.
-1-
Caution
Do not keep the AC adapter connected to the electrical
outlet for a long period of time. Dust that has collected on
the outlet may cause a fire.
When relocating the AD-1683, remove the AC to avoid a
possible electrical shock.
Precautions on Usage
Caution
If the AD-1683 malfunctions, stop using it immediately. Place
an "Out of Order" label on it or move the instrument to a
place where it can not be used by mistake. It is very
dangerous to continue using the instrument under such
conditions. Ask the nearest dealer for services.
Do not face the front of the AD-1683 directly toward an
electronic balance. Ionized air from the AD-1683 may affect
the measurement and cause a measurement error.
When used with a balance of other manufacturers, static
elimination can not be guaranteed.
Do not place the sample closer to the AD-1683 than specified.
The sample may become charged.
Do not place any obstacle between the AD-1683 and the
sample.
The stand can be attached to the workbench. The stand has
three holes with a diameter of 6 mm in 42.5 mm interval for
that purpose.
(To secure the stand: Bend the side plates outward to remove
the AD-1683, using much care not to separate the upper and
lower cases. Attach the stand to the workbench using the
screws. Replace the AD-1683 on the stand.)
1. Introduction
This manual describes how the AD-1683 works and how to get the
most out of it in terms of performance. Please read this manual
completely before using the AD-1683.
2. Features
The AD-1683 generates bipolar ions continuously by DC corona
discharge separately from positive and negative discharge
electrodes and directs the ionized air onto the charged body to
eliminate static electricity. The generated ions are well-balanced
in polarity and can eliminate static electricity regardless of the
polarity of the charged body. (See Fig.3.)
Static electricity
Generally, insulators such as plastics are prone to be charged
with static electricity when the ambient relative humidity is
below 45%RH. This may affect weighing and cause a
measurement error of several milligrams.
The AD-1683 can eliminate static electricity very effectively.

Note: Please confirm that the AC adapter type is correct for your
local voltage and receptacle type.
To prevent electrical shock, insert the POWER cable into a
grounding-type outlet and earth ground the grounding cable.
4. How to Use the AD-1683
4-1. Installing the AD-1683
Choose the installation site so
that the AD-1683 can be placed
beside the electronic balance
and a space wide enough to
place a sample (10 cm to 30 cm
from the front of the AD-1683)
can be secured. Place the
sample in front of the AD-1683
inside the specified area and
perform static elimination. Then,
weigh the sample using the
electronic balance.
4-2. Turning the power on
Insert the AC adapter plug to the AC adapter jack located on the
rear of the AD-1683. Insert the AD adapter into an electrical
outlet. The red LED at the center of the AD-1683 illuminates to
indicate that static elimination is available.
Note: Please confirm that the AC adapter type is correct for
your local voltage and receptacle type..
4-3. Finishing the use
Remove the AD adapter from the electrical outlet.
5. Maintenance
5-1.Cleaning
Caution
Remove the AC adapter from the AD-1683 before cleaning.
When used for a long period of
time, dust may collect around the
discharge electrode pins and
static elimination performance will
be lowered. To maintain the
elimination performance, clean the
AD-1683 periodically (once a
week). Use a cotton swab to clean
the electrode pins.

5-2. Replacing the discharge electrode pin
When the elimination performance
remains low even after cleaning
the discharge electrode pins,
replace the discharge electrode
pins with new ones.
Remove the AC adapter from the
receptacle and the AD-1683.
Using a pair of pliers, pull the
discharge electrode pin out.
Insert a new pin, using much care
not to bend the pin tip. Be sure to
insert the pin till stopped.
