Measurement Menu - Hach K1200 Manuel D'utilisation Simplifié

7.2 View menu
7.2.1 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 K1200 low range sensors measure dissolved oxygen up to a maximum value of 5000 ppb.
Below 2000 ppb the measurement cycle interval is 2 seconds. Between 2000 and 3000 ppb the
measurement cycle interval is 30 seconds. Above 3000 ppb the measurement cycle interval is
60 seconds. The K1200 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.
