Safety precautions
This section provides precautions for using the product safely and correctly and to prevent
injury and damage. The terms of DANGER, WARNING, and CAUTION indicate the degree of
imminency and hazardous situation. Read the precautions carefully as it contains important
safety messages.
WARNING
Electric shock
To prevent electric shock, ground the product.
Do not ground the product to dangerous places such as a gas pipe.
Samples may be dangerous substances. Fully understand the properties of the samples to be
measured, and handle them appropriately.
Fire
• For your safety, make sure to unplug the power plug from the electrical outlet when not in use.
• Clear dust on the power plug periodically (a few times a year).
If the power supply cord is left plugging into the electrical outlet for a long period of time, electrical
tracking may occur due to dust and moisture, and it may result in an ignition or a fire.
Fire or electric shock
• Do not bundle the power supply cord during use.
• Do not damage, bend, or stretch the power supply cord forcibly.
• If it cannot be plugged into an electrical outlet firmly, stop use of the power supply cord.
If may result in overheating, fire, or an electrical shock.
Be sure not to disassemble or modify the product, except as instructed in this manual.
It may cause electric shock or product failure.
CAUTION
Chemical hazard (solvent S-316)
Inhalation or accidental ingestion of a large amount of solvent S-316 may be harmful.
Observe the following rules when handling:
• Ventilate the work area sufficiently.
• Wear a protective mask and protective gloves.
• Wash hands well after handling the solvent.
Chemical hazard (hydrochloric acid)
Hydrochloric acid is toxic by skin or eye exposure.
If it touches the skin, immediately rinse with water.
If it reaches the eyes, rinse immediately under a large amount of running water and get medical
attention.
During dispensing liquids into the extraction tank, limit the solvent amount to 10 mL or less and the
amount of the measurement liquid to 20 mL or less, so that the total volume of liquid does not exceed
the upper limit line (30 mL).
If the liquid exceeds the upper limit line, the liquid may leak and cause short-circuit in the internal
wiring of the product. If liquid containing hydrochloric acid leaks and comes in contact with the skin,
irritation and burning may occur.
Discard the liquid collected in the beakers before overflow.
If liquid containing hydrochloric acid overflows and comes in contact with the skin, irritation and
burning may occur.

Take care not to pinch your fingers when opening or closing the right cover.
During closing the right cover, do not release your hand until you hear a click sound.
Avoid any impact on the product.
If the product is damaged and liquid leaks, the internal wiring may short-circuit.
If liquid containing hydrochloric acid leaks and comes in contact with the skin, irritation and burning
may occur.
CAUTION

Product Handling Information
Operational precautions
Use of the product in a manner not specified by the manufacturer may impair the protection
provided by the product. And it may also reduce product performance.
Observe the cautions below.
This product is specified for use with H-997. Do not use any other solvent than H-997 to
perform extraction and measurement. It may cause product failure.
Samples containing emulsifying substances (surface-active substances) cannot be
measured.
Samples containing acetone or toluene cannot be measured. These samples may
damage the product.
Samples containing impurities and samples with high viscosity should be filtered, diluted,
or otherwise preprocessed appropriately before measurement. If measured without
preprocessing, the tubing and valves may become clogged and product may get
damaged.
Take care not to spill samples or solvents on the main unit. It may cause product failure.
Avoid operating and storing the product under the following locations and conditions:
- Humidity above 80%.
- Temperature less than 0°C or over 40°C
- Locations subject to sudden temperature changes
- Direct exposure to sunlight
- Presence of corrosive gases
- Dusty locations
- Poor ventilation
- Locations subject to vibration
- Close proximity to large electric motors or voltage transformers
When handling liquids during measurement, calibration, or otherwise, remove the USB
memory stick from the USB memory port and cap the port. If a liquid spills on a USB
memory stick or the USB memory port, the liquid may enter the interior of the product
from the USB memory port and cause product damage.
Do not overturn the main unit. It may cause liquid to leak from the unit inside.
Do not press the keys or the screen with a sharp or hard object.
Do not block the fan vent on the back of the main unit.
Before performing maintenance or inspection, read and understand the chapter
"Maintenance" (page 87) in this manual.
Wipe with water when cleaning the exterior of the product, never use the organic solvent.
Make sure that the power supply voltage is correct for the product before switching the
power ON.
When the product will not be used for an extended period of time, remove the plug from
the power outlet.
Do not use the provided power cable for other than this product.

Solvent handling precautions
It is recommended that new solvent from the same production lot is used for calibration liquid
preparation, zero calibration, span calibration, and measurement. Solvents from different
production lots may have different mix ratios.
If it is necessary to use solvents from different production lot or reprocessed solvent, mix all
the volumes to be used in a glass container, in order to equalize all mix ratios.
Disposal of the product
When disposing of the product, follow the related laws and/or regulations of your country.
