3.2Enter calibration data of LANGE Cuvette Tests
3.2.1Overview
Each POCKET COLORIMETER II has two channels in which measurements can be
made. Each channel (measuring range) will accept user-defined calibration data.
This application instruction contains the calibration data of the LANGE Cuvette Test
for Chlorine/Chlorine dioxide/Ozone:

Select the calibration data of maximum two measuring ranges which will be the
suitable one.
Each programming procedure has only to be followed once prior to the first test
evaluation.
For detailed information please read the POCKET COLORIMETER II instruction manual.

LANGE Cuvette Tests
DANGER
Handling chemical samples, standards and reagents can be dangerous. Users
of this product are advised to familiarize themselves with safety procedures
and the correct use of chemicals, and to carefully read all relevant material
safety data sheets.
To analyse Chlorine, Chlorine dioxide or Ozone follow the working procedure
enclosed in the according Cuvette Test LCK 310.
4.2Quality assurance
The measurement results must be subjected to plausibility checks (dilute and/or
spike the sample).
Regular checks with corresponding standard solutions (see Section 5 Replacement
Parts and Accessories on page 27) ensure that your measurement system is
functioning properly and is being correctly operated.

cover the cuvette.
5.Press BLUE key. "0.00" is displayed.
6.Remove the instrument cap and insert the sample cuvette.
7.Place the instrument cap over the cell holder to cover the cuvette.
8.Press GREEN key.
