Numeric view
This is the default view and shows the measurement value, sample temperature value, and a graph
showing the measurements during the set time frame. The display is refreshed after each
measurement cycle which can be configured to suit user requirements.
The K1100 and M1100 low range sensors measure dissolved oxygen up to a maximum value of
2,000 ppb. The K1100 and M1100 high range sensors measure dissolved oxygen up to a maximum
value of 40 ppm. 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.
