6.3 Trace Mode
Trace mode features value tracing on a graph with duration configurable from three minutes up
to four weeks. The graph is composed of 60 record sets over time interval T. Each set of data
(T/60) is displayed by calculating the mean, maximum, and minimum value of the previous 60
values. When a new data set is calculated, the set will be displayed on the right and thus shifting
the previous sets to the left by one unit. If time (T) is set for 60 hours, then each displayed set
will represent a calculation of the mean, maximum, and minimum values of the data recorded
during the hour (T/60). The horizontal x-axis of the graph is divided into 12 marks, with each
mark representing T/12, and five data sets between each mark. The user can set the Turbidity/SS
graph range under Mode in Settings (see section 7.4). The smaller the range, the higher the
display resolution. Trace mode shows the real-time measurement value and unit, and temperature
value and unit at the bottom of the screen, as seen in the following illustration.
Attention: If the time interval is reset, the trend in the data will not be retained, and will start a
new trace record.
Note: The time is displayed as (XX: XX) (hr: min); e.g. four weeks (672:00).
