7.2.1 Numeric view

This is the default view. Display shows the numeric measurement value identified for each gas
measurement channel used, a graphic showing measurement value evolution during the set time
frame, and sample temperature. The display is refreshed after each measurement cycle ( based on
the oxygen level for LDO sensor). This display can be configured to suit individual conditions and
convenience.
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 . 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 . 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.
