1. Safety Precautions
This section explains the precautions that must be observed to prevent injury to the user or other persons or damage to
property.
The following symbols classify and explain the degree of harm or property damage that may result if the contents of the
symbols are ignored and the product is used improperly.
This symbol indicates the extent of harm or damage that could potentially result in
injury or physical damage if the information is ignored and the product is handled
incorrectly.
This symbol indicates a situation in which the measurement could be adversely
affected, preventing correct measurement results from being obtained if the
information is ignored and the product is handled incorrectly.
If a 3-way check valve is inadvertently used when measuring a sample containing fibers or solids, the
valve could become clogged, and the measurement will not be possible. Exchange the 3-way check
valve with the enclosed 3-way cock. (Refer to section “5. Measurement (3) Measuring a sample
containing fibers or solids” on page 15 of this manual.)
The key components are made of acrylic materials. Acrylic materials have a low resistance to solvents
such as alcohol, so do not measure such matters. The acrylic material could be adversely affected, such
as cracking the acrylic material.
Avoid taking measurements in conditions where the temperature changes. Temperature changes may
cause air bubbles to form in the sample being measured, and this may cause measurement errors.
If there is a temperature difference between the measurement sample and this device, make sure to
match the temperatures before measurement.
For example, if the sample has been stored in a refrigerator, let it sit until it reaches room temperature,
and then measure, taking care not to inhale any of the air bubbles generated.
Samples containing milkfat ingredients should be measured at the end of the measurement session.
After measuring, clean the device thoroughly.
