meter for the cartridge is set to zero.
All old calibration data are now overwritten with the new calibration
data from the sensor code. The sensor code data is checked by the
system. If an error is indicated, check the sensor code and, if
necessary, enter the sensor code again.
The LINK2SC procedure offers a secure method of data exchange
between process probes and LINK2SC-compatible photometers
using an SD memory card or via a local area network (LAN). Two
different options are available:
a. The pure laboratory control measurement
b. A matrix correction that involves the measurement data
generated in the laboratory being used to correct the probe
During a pure control measurement, the measurement data is
transferred from the probe to the photometer where it is then
archived together with the photometric reference data that has
been recorded.
During a matrix correction, the reference data generated in the
laboratory is transferred to the probe to be used for the correction.
The matrix correction process requires operating steps to be
completed on the sc controller and on a LINK2SC-compatible
photometer.
Refer to the LINK2SC user manual for a detailed description of the
LINK2SC procedure.
When using the LINK2SC software, sections

ISE probes offer different options (refer to
the sensor value with laboratory values (as a reference value).
The laboratory value of the water sample is entered as nitrate
nitrogen (NO –N) and/or as ammoniacal nitrogen (NH
