Safety Information

(1) Meaning of markings

The signal terminology and symbols related to warnings in the instruction manual are defined below. The alert symbol mark ( damage and also means “Refer to the instruction manual.”

Indicates the degree of hazard which can lead to death or serious injury if you fail to operate the product properly. Serious injury means an injury such as loss of sight, burns (high temperature or low temperature), electric shock, bone fracture and poisoning, and the aftereffects of the injury remains or the injury requires hospitalization or long periods of outpatient treatment.

Indicates the degree of hazard/loss which can result in injury or property damage if you fail to operate the product properly. Injury means an injury not requiring hospitalization or long periods of outpatient treatment and refers to burns or electric shock. Property damage refers to widespread damage to the home, household goods and livestock, pets, equipment, materials, etc. (damage to other than the product itself).

: General caution mark) indicates the possibility of hazard or

Electric Shock

Always verify that the power is off before connecting or disconnecting the power cord

plug and external connection connectors. In addition, do not connect or disconnect them with wet hands. Water or reagent entering the product may short the circuits and cause electric shock or fire.

Do not operate the product with wet hands. It may cause electric shock or fire.

The product main body must be grounded. If a problem occurs in the power supply

system, an electric shock may result.

Hazardous substances

When using the liquid chemical pump to clean the electrodes by chemical, procure the Safety Data Sheet (SDS) for the reagent to be handled from the vendor and handle the reagents safely in accordance with the description.

Injury

Do not touch the arm section during measurement. During the cleaning operation, the arm moves and there is the danger of pinching your fingers or getting injured.

Disassembly and Modification

Do not disassemble or modify the sections of the product that are not described in the instruction manual. The product can be damaged.

Caution Label Lost

If any caution label affixed to this product becomes too difficult to read or lost, please order a new one through your local sales agent or our sales office and affix it to its original position.

(3) Notes on use of the instruction manual
