6.3 Trace mode
The feature of the trace mode is the record duration which can be set by the user (range from
three minutes, up to four weeks). The trend graphic records the measurements in the past T time.
The trend is recorded by the 60 group structure. Hence, each group of units is recorded in T/60
time interval. The trend line is constructed by all value data which is calculated to the average
(Mean Value), maximum (Max Value) and minimum (Min Value) form. When the latest T/60
record shows in the rightmost of the trend graphic, all the previous record will be moved to the left
side of the graphic. For example, T is set to 60 hours, then each set of records will be calculated to
the average, the maximum, the minimum values after one hour(T/60 = 1), each time interval.
Timeline of trends which is divided into 12 depictions showed on the horizontal axis of the display
is on behalf of each characterization interval T/12. So, every depiction has 5 (T/60) sets of records.
Users can set the corresponding Cond./Conc. measuring range in its set-up menu(see section 7.4).
The smaller the range is set, the higher resolution of the display is. The trace mode is shown as
below. There are also real-time measurement value, & unit, and temperature value & unit which
are displayed in the bottom of the screen.
Attention: When the time interval has been reset, the trend in the data will not be retained, it will
start a new trace record.
Note: The time display format (XX: XX) (hr: min), for example, appear as four weeks (672:00).
