EAN-128

EAN-128 was designed to express a wider range of information such as logistics data or commercial transaction data in addition to the information stored in currently popular JAN/UPC/EAN and Standard Distribution Code (ITF).

Edge Input

An external signal input which is considered to be ON when it exceeds a certain voltage.

Efficiency

The ratio between output power and input effective power.

Electric Conductivity

How easily electricity can pass through is represented in figures. Complete ion concentration of the liquid is digitalized and the unit "μS/cm (micro Siemens per centimeter)" is used. Electric conductivity of tap water is around 100 to 300 μS/cm.

Electronic Measuring Instrument

Measuring instruments amplify electric signals input at various levels, calculate them, and display the result. They also record the measured values as necessary. Electrical signals are processed in either analog or digital format.

Emissivity

Even if the temperature is the same, the amount of a radiated infrared beam differs depending on the material or surface condition of the objects. Emissivity is the ratio of radiant energy of an object using a black body as a reference. The following is an important formula for understanding emissivity.

Envelope Waveform

A waveform which connects the peak (bottom) values of an amplitude waveform. It is used to see the trend of phenomena such as vibration.
