Testing Procedure - VOLTCRAFT CLB-600 Bedienungsanleitung

9. Testing Procedure

Samples should be analyzed as soon as possible after collection. Exposure to
sunlight, other strong light, or agitation will accelerate the reduction of chlorine.
• Use the measuring cup to fill the cell with 10 ml of sample liquid then screw the cap on.
Use a lint free soft cloth to dry the cell (7) and wipe any fingerprints off before inserting
into the cell chamber (4).
• Press to turn the meter on.
• Press and hold
Put the cell (7) into the chamber (4), and

• Unscrew the cap (6) and insert one FCL
(DPD-1) strip or one TCL (DPD-4) strip
into the sample solution.
• Fan the strips in a gentle back and forth
motion (approximately 2 strokes per
second) for 20 seconds, then remove the
strip.
Screw the cap (6) back on and wipe the cell (7) dry, taking care not to leave any fingerprints
•
on the glass.
Bubbles can lead to incorrect measurements. If needed gently swirl the cell (7) to
