The K-M1100 low range sensors measure dissolved oxygen up to a maximum value of 5000 ppb.
Below 2000 ppb the measurement cycle interval is 4 seconds for 2 channels and 6 seconds for
3 channels. Between 2000 and 3000 ppb the measurement cycle interval is 30 seconds. Above
3000 ppb the measurement cycle interval is 60 seconds. The K-M1100 high range sensors
measure dissolved oxygen up to a maximum value of 40 ppm, the measurement cycle interval is
4 seconds for 2 channels and 6 seconds for 3 channels. Should the measured concentration go
above the maximum value for the sensor then the measurement cycle is increased to 60 seconds
and an Out of range message will be displayed. An arrow symbol to the right indicates if the value is
increasing, decreasing, or remaining constant. Once the measured value falls below the maximum
value, the measurement cycle returns to the pre-defined interval.
