Questions answered in these manuals
How do I calibrate the DO600 meter?
Turn the meter ON, press and hold the MODE/HOLD button until % is displayed, then press and hold the CAL/RECALL button until CAL is shown. The meter will blink '101.7' and show 'SA' before returning to normal mode.
What happens if the meter is not used for more than seven days?
A 3-minute waiting period is required before a measurement can be made, as the electrode needs to re-polarize.
How long does the startup polarization period take?
A three minute (approx.) polarization period must elapse before measurements can be made.
How often should calibration be performed?
Calibration should be performed on a daily basis.
What is the measurement range for dissolved oxygen concentration?
The meter displays concentration from 0 to 20.00ppm (mg/L).
