3.1.1 Key-Functions
ZERO/SCROLL (BLUE key) : In measurement mode, sets the instrument to zero. In
menu mode, scrolls through menu options. Also scrolls numbers when entering or
editing a value.
READ/ENTER (GREEN key) : In measurement mode, initializes sample
measurement. In menu mode, selects a menu option. When entering numbers,
moves one space to the right. Confirm the function when the entry is complete.
3.2 Enter calibration data of LANGE Cuvette Tests
3.2.1 Overview
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 Tests
for COD:
21
System start up
• high range with POCKET COLORIMETER II 600 nm
• LCK 014: 1000-10000 mg/l COD
• LCK 114: 150-1000 mg/l COD
• low range with POCKET COLORIMETER II 450 nm
• LCK 314: 15-150 mg/l COD
• LCK 614: 50-300 mg/l COD
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.
