AD-1683

CautionDC Static Eliminator
Instruction Manual• Do not keep the AC adapter connected to the electricaloutlet 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 apossible electrical shock.

Precautions on Usage
Caution• If the AD-1683 malfunctions, stop using it immediately. Placean “Out of Order” label on it or move the instrument to aplace where it can not be used by mistake. It is very
dangerous to continue using the instrument under suchconditions. Ask the nearest dealer for services.

To prevent electrical shock, insert the POWER cable into agrounding-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 sothat the AD-1683 can be placed
beside the electronic balance
and a space wide enough toplace a sample (10 cm to 30 cm
from the front of the AD-1683)
can be secured. Place thesample in front of the AD-1683
inside the specified area andperform static elimination. Then,
weigh the sample using theelectronic balance.

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

Mass
Approx. 300 g (including the stand)• Do not face the front of the AD-1683 directly toward anelectronic balance. Ionized air from the AD-1683 may affectthe 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 thesample.
• The stand can be attached to the workbench. The stand has
three holes with a diameter of 6 mm in 42.5 mm interval forthat purpose.
(To secure the stand: Bend the side plates outward to remove
the AD-1683, using much care not to separate the upper andlower cases. Attach the stand to the workbench using thescrews. Replace the AD-1683 on the stand.)

To Use the AD-1683 Safely

1. Introduction

Thank you for your purchasing the AD-1683 DC static eliminator.
Please read this manual completely before using the AD-1683.

This manual describes how the AD-1683 works and how to get themost out of it in terms of performance. Please read this manualcompletely before using the AD-1683.

Warning Definition
The warning described in this manual has the following meaning:

CautionImportant information to alert you to a situationthat may cause injury and/or damage to yourproperty if instructions are not followed.

When operating this instrument, be sure to observe thefollowing 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.

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 toeliminate static electricity. The generated ions are well-balanced
in polarity and can eliminate static electricity regardless of thepolarity 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 isbelow 45%RH. This may affect weighing and cause ameasurement error of several milligrams.
The AD-1683 can eliminate static electricity very effectively.

3. Part Names• The AD-1683 is not explosion-protected. Do not use theinstrument where flammable solvents or dust exits.

External Dimensions
4-2. Turning the power on
Insert the AC adapter plug to the AC adapter jack located on therear of the AD-1683. Insert the AD adapter into an electricaloutlet. The red LED at the center of the AD-1683 illuminates toindicate that static elimination is available.
Note: Please confirm that the AC adapter type is correct foryour local voltage and receptacle type..

4-3. Finishing the use
Remove the AD adapter from the electrical outlet.

5. Maintenance
5-1.Cleaning

CautionRemove the AC adapter from the AD-1683 before cleaning.
When used for a long period oftime, dust may collect around thedischarge electrode pins andstatic elimination performance will
be lowered. To maintain theelimination performance, clean theAD-1683 periodically (once aweek). Use a cotton swab to clean
the electrode pins.

• Do not touch the discharge electrode pins. It may cause anelectrical shock.
• Use the specified AC adapter only. Please confirm that theAC adapter type is correct for your local voltage andreceptacle type. If an AC adapter other than specified isused, 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.
