Term Description
Asymmetric
Potential
The electrical potential across the measuring
and reference half-cells of an electrochemical
sensor at the Isopotential Point.
Boredom Switch
An automatic timer built into the TB84PH
Advantage Series analyzer that returns the
instrument to the Measure Mode of Operation if
a user has entered another mode of operation
and has not initiated another action for
twenty minutes.
EEPROM
Electrically Erasable Programmable Read Only
Memory. A type of non-volatile memory that
can be electrically programmed and erased.
Efficiency
A value that represents the percentage of the
theoretical, Nernstian temperature compensated
output from an electrochemical sensor.
EPROM
Erasable Programmable Read Only Memory. This
memory holds the operational program for the
microcontroller integral to the analyzer.
Ground Loop
A path between two separate ground connections
thus allowing unwanted current flow through
the measurement cabling or circuitry.
