1. Feature

DONG IL TECHNOLOGY LTD

Welcome to become a customer of DIT.

Static electricity can cause lower production efficiency, such as

damage on circuit pattern of products, particle deposition and etc.

“ARS-H002ZA” is the portable voltmeter, which can monitor and
manage static electricity easily on production lines.

1) Detection of the electrostatic spot

2) Selecting the place for ionizer installation

3) Checking the Ion balance of ionizer and measuring static
charge

▶ Precision mode and Expansion mode

Precision mode detects static electricity from 0V to±2.00kV, and Expansion mode detects it
from ±2.00kV to ±20.0kV. Both modes are changed automatically during usage.
Resolution is 10V from 0V to ±9.99kV. When static electricity is under -10.0kV or +10.0kV,
the resolution is 100V. In case of Ion Balance mode, it is able to be displayed in unit of 1V.

▶ Rotary sensor head

ARS-H002ZA has a rotary head which makes convenient measurement in narrow space.

Also a sensing plate for ion balance is designed with rotary integrated structure,
so it is more convenient for use and storage of the product.

▶ Real time Monitoring System by PC

It is able to check the measured data in real time and save the data via USB port.
[Monitoring program is provided free of charge]

7. Operating Instruction

7.3 Setting zero point adjustment

In case that the initial value is not “0” though following the measuring set-up(7.2),
Please set zero point adjustment as below.

1) Setting zero point adjustment on Electrostatic mode

① Position a sensing hole toward non-electrostatic area.
② After pressing [ZERO] button, check if the value is changed to “0” on display.

2) Setting zero point adjustment on Ion Balance mode`

① Ion balance plate of head should be faced to the object.
② Touch an earthed wire on the plate, or remove remaining electric charge by finger

touch.

③ After pressing [ZERO] button, check if the value is changed to “0” on display.

Warning!!

1) If users set zero point adjustment during measurement, the measured value is not
accurate by distortion of reference zero point.

2) Setting zero point adjustment is not worked in below cases.([Zero] button is not
available) ① Out of range : over ±0.80kV[Electrostatic mode] / over ±100V[Ion
balance mode) ② During HOLD function

2) Check the setting for ion balance mode as below.

[ex1. measuring +1.25kV] [ex2. measuring -12.5kV]

When “HHH” or “LLL” is displayed, the level of static electricity is over measurable range.
In this case please stop measuring because integral sensor can be damaged.

※ HHH : over (+)voltage measurable range[+20kV], LLL : over (-)voltage measurable

range[-20kV]

9. Attention

ARS-H002ZA is a portable electrostatic voltmeter, which includes susceptible parts.
Please read carefully the attention below before use.

1) After Reading the instruction manual, use the product according to instruction manual.

2) Make sure to keep the product away from water/oil/solvent/power/etc.

3) Do not use the product in place with corrosive gas such as acid/alkali/etc.

4) Do not give strong impact or vibration to the product. Sensor could be damaged.

5) Make sure to avoid a loaded heavy weight on the LCD panel.

6) Do not use the product in place with strong electromagnetic noise. It may cause
malfunction of integral micro-chip.

7) Make sure to ground the product with a provided earthed cable before use.

8) The Sensing hole part should be avoided condensation.

9) Make sure that the sensing hole is not polluted by water and dust.

10) Do not touch or put sharp objects to the sensing hole.

11) When measuring ion balance, do not face the sensing hole to the object without the
sensing plate.

12) Do not press buttons on main body with excessive force.

13) Keep the sensing plate at a humidity under 60%RH because of its high insulation.

[recommended to use desiccator or plastic bag and desiccant]

14) The sensing plate should maintain its insulation. Otherwise, the measured value is not
guaranteed. Please check the degree of insulation regularly as below.

<How to check the degree of insulation for the sensing plate>

① After charging 100V to the sensing plate, check the decreasing speed. It means that the

insulation resistance is lower as much as the decreasing speed is faster.

② Measure the insulation resistance on the bridge of under the sensing plate. The insulation

resistance should be over 10TΩ (10¹³Ω).

15) Do not break or assembly the product. It may cause malfunction of the product.

Also it is subject to restriction for exchanging or repairing the products.
