Getting started

Onscreen instructions are available for all test methods.

Achieving accurate results

Blanking

Blanking is critical and sets the zero level for each test.
For most test methods, the blank is a sample without any reagents added.
The onscreen instructions show blanking as the first few steps, however, the “blank” can be prepared in a separate tube and blanking carried out just before the measurement step.

Best practice when testing

Rinse equipment thoroughly with deionised water or the water being tested.
Measure volumes accurately as shown (or use a pipette or syringe).
Use the correct YSI reagents and observe all safety information supplied with them.
Check for bubbles and remove them as shown.
Align tubes as shown. Always use the tube cap as it excludes light from the optics.
Keep the instrument clean. Dry all tubes before placing them in the optical cell.
