6.3.4.5 Oscilloscope Display
Besides the simple display of the measured value the software offers an
oscilloscope-like display of the last 100 measured values. The time axis
depends on the selected measuring time. The used scaling is displayed
below the diagram.
The scale of the amplitude axis is given by the connected probe and the
selected sensitivity of the FM 302. It covers the full range of values possible
in the set configuration. In measuring mode relative measurement the
baseline is moved corresponding to the set reference value. See also

Command "relative.
To better display the change of small values the box "x10" below left at the
display can be check. This reduces the displayed value range to one tenth
what produces a display ten times more sensitive.
By pressing the button "save image" the current image will be saved. The
file format can be chosen from the formats JPEG, PNG, BMP, TIFF, GIF
and EMF.
For the display the values are taken from the digital sampling. With
minimum measuring time of 0.1 s the maximal possible sampling rate
is 10 Hz. For displaying faster signals a real oscilloscope can be
connected to the analog output of the Teslameter FM 302.
