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.

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.
