11.2 Controlling the Measurement
The measurement is controlled in the same way you would control a normal Sound Level
Meter measurement, using Start/Pause , Continue , Back-erase and Reset
pushbuttons, see Chapter 3 for more details.
If you have set the Charge Injection Calibration parameter to On, then CIC is performed at the
start of the measurement and at the end of the measurement. An Exclude marker is set on the
logging profile at the point where CIC is being performed. The update of the Total parameters
is stopped while CIC is being performed. You can see the results of the CIC under Total
parameters, CIC Result 1 and CIC Result 2.
11.2.1 Annotating a Project
While using the logging software you can annotate measurements using the normal method of
adding annotations to a project, before or after a measurement, or while the measurement is
paused. The annotations can then be viewed by tapping on the Annotations icon or tapping the
Main Menu and selecting Explorer from the list of options. section 3.5.
