Digital
Representation of a variable, e.g. time, in the form of characters or numbers. In its digital
representation, this variable can be changed only in pre-defined steps, in contrast to
"Analog".
EEPROM
Electrically Erasable Programmable Read Only Memory
EEPROMs are often used where individual bytes of data (e.g. configuration data or runtime
meters) change over time and must be stored safely in the event of a mains power failure.
ElectroMagnetic Compatibility
Definition as per the EMC law:
EMC is the capability of a device to operate satisfactorily in an electromagnetic environment
without itself emitting electromagnetic signals which interfere with other devices in that
environment.
eLive
As of release version 09, MicroSAM features the eLive injection, which controls the position
of the injection content, prevents the mixing with carrier gas, and prevents the influences of
viscosity during injection in the case of certain gas compositions.
Ethane
Ethane is a chemical compound belonging to the group of alkanes (saturated hydrocarbons).
Ethane is a colorless and odorless gas with the formula C
2
H
6
. Ethane is primarily used for
heating and combustion purposes. Ethane is a main component of natural gas, in addition to
methane.
Ethine
Ethine (or acetylene) is a colorless gas with the formula C
2
H
2
. Ethine is the simplest
representative from the group of alkines.
Firmware
Firmware (FW) is software which is embedded in a chip in electronic devices – unlike
software that is stored on hard drives, CD ROMs, or other media. These days, the firmware
is mostly stored in a flash memory or an EEPROM.
The firmware mostly contains elementary control functions of the device, as well as input and
output routines.
