The life span of key parts depends on user’s environment and can be used optimally
through periodic check. Therefore, regular inspection ensures optimal performance of
product, so take regular inspection and maintenance at least every year. Inspection of the
appearance of the product shall be visually checked to see if there is any damage, and the
attachment of the medium or foreign substances to the sensor will make it worse, so they
shall be removed regularly.
■ Inspection of Products
- When cleaning the tank, remove any attachments that attach to the instrument.
- If the measurement is moving fast or stirring, check the probe for mechanical damage
or insulation.
- The water resistance of the probe shall be checked periodically, as the insulation of
the probe may cause errors and malfunctions.
- When measuring highly adhesive material, it is necessary to check whether the
attachment is growing or not, and if there is growth, remove it periodically.
- Check the level and presence of measure object in the tank before removing it.
- Wear gloves when removing it, to prevent a burn.

- Disassemble work shall be done with the power off.
- External ground is located on top of cable entry, and the grounding wire to connect
external ground shall be 4㎟ (4mmSQ). (Internal ground is connected before shipment.)
- The internal grounding wire shall be the same size as the power line, and the size of the
internal grounding terminal lug shall be 3.1㎟ (3.1mmSQ). If the power line is larger than
3.1㎟, connect the ground wire without terminal lug.
- Use the cable gland connection or metal pipe line lead-in on the wire inlet, and use a
product with equivalent Ex-proof certificate to connect it with the external line lead-in
method.
- For non-use external wire inlet, use a closed plug that passes safety certificate above
equivalent performance with the product.
Make sure to insert a washer if the terminal lug is removed from the ground
terminal, and then re-connected. (Loosening prevention)
