Using The Graphical Display; Displaying Only Selected Channels; Finding The Value Of Individual Data Points - RBR 1050 Series User Manual

Using the graphical display

Any data that has either been retrieved or loaded from a previously saved file is
plotted on the graphical display.
Vertical black bars indicate interruptions in data collection. These interruptions
may be due to thresholding, changing the batteries or spurious electrostatic
discharges.
The following image is an example of data collected by an XR-420 series data
logger equipped with a temperature sensor and a pH sensor.

Displaying only selected channels

Each available sensor has a coloured button
labeled with an abbreviation for its data type at the
bottom, left-hand side of the screen. Clicking any
of these buttons will display readings of only that
type. Additional channels may be added by
depressing the 'Shift' key while selecting a button.
Clicking ALL will display readings from all the
available sensors and derived units at once.

Finding the value of individual data points

Individual values may be found by clicking the left
mouse button anywhere on the vertical axis above
or below the target value. Above the graph a date,
time and value will be listed. The units are
standard engineering units and are the same as
those used for the vertical axis.
If the left mouse button is held down, the user may
move the cursor from side to side along the graph,
displaying values all the while.
