LFOx1400(-ID) Overview
29 ba75523e04 07/2011
The conductivity basic module can be used as an independent conductivity
measuring cell. For this purpose, unscrew the DO module and close the open
plug connection with a closing cap.
The DO module is connected to the conductivity basic module via a water-
tight, three-pole plug connection. The conductivity basic module measures
the temperature, which is required for the determination of the DO content.
For this reason the DO module only works in conjunction with the conductivity
basic module.
Automatic sensor
recognition
In the plug connector of the LFOx1400-ID sensor, data is stored for the auto-
matic sensor recognition function. Among other, this data includes the sensor
type and series number. Besides, the calibration data is written in the sensor
with every calibration procedure. When the sensor is connected, the data is
called up by the meter and used for measurement and measured value doc-
umentation. The correct data is always used automatically if the sensor is op-
erated with several meters because the data is stored in the sensor.
To be able to use the automatic sensor recognition function, a meter is
required that supports the function. More information on the automatic sensor
recognition function is given in the operating manual of the meter.

1.2 Instrument identification
A series number is printed on both LFOx1400(-ID) modules. Keep these
numbers ready if you have questions to ask the SI Analytics service
department. The series numbers contain the following information:
Conductivity basic
module
The number is printed on the shaft.
Dissolved oxygen
(DO) module
The number is printed on the cap nut.
