Measurement Mode
The Measurement mode appears after starting the
instrument or changing into BA mode. This is the
mode where measurements are taken, contrary to
Project Mode where the accepted measurements and
calculated results are presented. The soft key in the
lower left corner lets you switch between these two
display modes. The Measurement mode may not be
accessible and therefore the soft key is greyed out if
an already stored BA measurement has been loaded
and is currently open. Pushing the Cancel ( ) button
will close the current measurement project and start a
new one. If you want to reuse some or all of the current
data click Yes when prompted and select the wanted
data to be reused (see
“Start a new project” on page
99“Start
).
Upon loading an existing project from the memory,
pressing the softkey
Activate will allow additional
measurements to be made inside the loaded project
(see
“Continue an existing project” on page 99 )
