Hand-held Analyzer Types 2250 and 2270 – User Manual

051114 001 (containing data for a whole day – November 14th)

051115 001 (containing data from midnight to the middle of the day on November 15th)

If you did not select Auto-naming of Projects then you would have the following projects

(assuming the Project Name Prefix parameter was set to Project and no projects had been saved

before in the directory):

Project 001

Project 002

Project 003

If you have set the Charge Injection Calibration parameter to On, then a CIC calibration is

performed at specified times of the day. An Exclude marker is set on the logging profile at the

point where the CIC is being performed. The update of the Total parameters and the Periodic

Reports is stopped while the CIC is being performed. You can see the results of the CIC

calibration under Total parameters, CIC Result 1 to 4.

The CIC result can be either ‘Passed’, ‘Background noise too high’ or ‘CIC Ratio deviates

from Ref.’ (The ‘Ref.’ mentioned here is the reference created by the very first manual CIC, and

is the one used as the reference to all subsequent CIC ratio measurements, see section 5.10.)

Note: If a level trigger is active when the CIC is due to start, then the CIC will not be done.

12.2.1 Annotating a Project

Measurements can be annotated in the same way as you annotate Logging measurements. See

section 11.2.1.

12.2.2 Recording the Signal

Signal recordings can be done in the same way as described under Logging measurements. See

section 11.2.2.

12.3 Displaying the Results

The Enhanced Logging Measurement screen includes three tabs at the bottom: Profile,

Spectrum and Broadband view – as the Logging Measurement screen does. You view data in

the same way as in the Logging module. You mark and annotate sound categories and edit

markers and annotations in the same way as in the Logging module – please see Chapter 11.

The Result Selector (first item in the third line of the Status Field) determines whether results

from the Total, Logged, Logged (100 ms) or Report measurement are displayed.

If you need to display data from another day of the measurement, then use Explorer to select

and open the project from that day.
