DENSITYSame as density meter*: When pre-heating circuit does not exist, 0 to 100% is almost in proportion to 0 - (the highest level WI value inthe measurement range).When preheating exists, about 20 to 100% is almost in proportion to 0 - (The highest level WI value of themeasurement range).The lamps of both alarm and fail of the computing station are lighted in the following case.1) Lighting of the alarm lamp.
