Data Logger - Pce Instruments Pce-Tds 200 Serie Bedienungsanleitung

5.1.8 Overview screen
The meter enables the numerical and graphical display of several measured parameters in the
measurement display, the Overview screen. It is possible to display up to four individually
selectable measured parameters numerically and up to two individually selectable measured
parameters graphically. The selection of the measured parameters to be displayed is made under
the menu items Graphical view and Numerical view by placing check marks.
5.1.9 Damping
The damping influences the measured parameters flow velocity and volume flow. It can be set to
a value within the range of 0 ... 60 s. The setting 0 s deactivates the damping of the measurement.
5.1.10 Absolute values
The Absolute values menu item makes it possible to prevent negative values from being displayed
for the parameters flow velocity and volume flow. With the setting ON, in case of a negative
volume flow, the measured value is displayed with a positive sign. The arrangement of the
upstream and downstream sensor thus has no influence on the sign in front of the measured
values in terms of the flow direction.
5.1.11 Lower cutoff
The Lower cutoff represents the flow velocity above which the meter displays a flow velocity of 0
m/s. In the event that the zero point fluctuates despite a set zero point, this value can be
increased.

Data logger

The Data logger of the instrument allows to record all measured parameters. The time period as
well as the memory interval can be freely configured with the help of this menu.
5.2.1 Start condition
The data logger can be started either manually by pressing a key while you are in the data logger
dialogue or automatically from a date that is set in this menu.
5.2.2 Stop condition
Three different options are available for stopping the data logger. It can be stopped manually by
pressing a key when you are in the data logger dialogue, on a certain date or after an adjustable
time interval.
5.2.3 Interval
The time interval for saving the measured values can be set to a value between 1 s and 12 h via
an input dialogue.
5.2.4 Records
In this menu, all saved records are displayed and by selecting a record, information on the start
and stop time as well as the number of saved data points are displayed. One data point reflects
the one-time storage of all measured parameters.
5.2.5 Delete all
By selecting this menu item and confirming via the dialogue, all saved data records are deleted.
