Initial commissioning

3.4.1 General information

 

Use calibration after

initial ommissioning

The sensor UV 701 IQ SAC was calibrated in the factory for the parameters 

SAC 254, dissolved

 and 

SAC 254, total

. The sensor is immediately ready to 

measure.
After the initial commissioning, a user calibration is required for all correlated 

parameters (

CODds correl.

, 

CODto correl.

, 

TOC correl.

, 

BOD correl.

, 

DOC 

correl.

) (see section 4.3). 

CAUTION

Never look into the measuring window or put objects into the 

measuring window during operation! The emitted UV radiation 

can damage the eyes!

In the case of authorized use, inadvertent eye contact with the 

light beam is not possible.

How to adjust the settings is described in the following section (sec

-

tion 3.4.3).
