Note
• The criteria of stability judgment in the automatic hold measurement are as follows.
Dissolved oxygen: Display value change for 10 seconds is less than 0.03
mg/L and temperature change is less than 2.0°C.
Oxygen concentration: Display value change for 10 seconds is less than
0.1% and temperature change is less than 2.0°C.
Saturated oxygen concentration: Display value change for 10 seconds is less than
0.3% and temperature change is less than 2.0°C.
• "Ur" (Under) lights when the measured value is below the display range and "Or" (Over)
when the measured value is above the display range. For details on how to correct them,
refer to "The measured value is out of the measurement range" (page 92).
