Measurement caliper tool
A caliper tool is available in the context menus when you right
click anywhere in the main ECG window, and select
Show
Calipers
.
Calipers for amplitude and duration measurements will appear on
the waveform.
Hover with the mouse over the caliper area. When you are close
to the dotted line, the mouse cursor will change to a cross and
you can now click and drag the caliper to a desired position
without changing the distance.
When you are close to the vertical line, the mouse cursor will
change to a double arrow, and you can then drag the vertical line
to a desired position.
When you right click when the arrows or cross is present on the interval calipers, a special context menu appears
that allows you to use the displayed caliper value to modify the ECG interval measurements. You can also select
March Out
to repeat the interval caliper over the duration of the recording. You can use any of the vertical solid
lines to expand or shrink the marching calipers, and the horizontal dotted line to drag the whole series to a different
position.
