3.0 OPERATION
3.1 T80 T
RANSMITTER
The ECD Model T80 transmitter is an intelligent, single or dual channel
multi-parameter transmitter designed for the online continuous
measurement of pH, ORP, pION, conductivity, resistivity or Dissolved
Oxygen in a general purpose industrial environment. The Model T80
transmitter digitally communicates with any ECD S80 digital sensor.
The measurement identity is contained in the sensor's memory. When
an S80 sensor is connected to the transmitter, it automatically
configures the transmitter's menus and display screens to the
measured parameter.
The functions associated with each key are displayed on the screen, above the key for the Selection Adjustment Keys
and to the left of the key for the HOME and BACK keys. Press any Selection Adjustment key twice within one second
to enter the HOME Menu Screen.
3.2 LQ800 C
ONTROLLER
The ECD Model LQ800 transmitter is an intelligent, single to
eight channel multi-parameter controller designed for the
online
continuous measurement
conductivity, Resistivity, Dissolved Oxygen, Flow, and Level in a
general purpose industrial environment.
The model LQ800 controller digitally communicates with any
ECD DS80 digital sensor. The measurement identity is contained
in the sensor's memory. When a DS80 sensor is connected to
the controller, it automatically configures the controllers,
menus, and display screens to the measured parameter.
