New look

Measurement Partner now has a new, cleaner look. For example there is no longer a difference between Data and Maintenance mode and managing licenses and installing software on your instruments is now just one click away. All changes are designed to make the software easier to use and more intuitive.

New Look

Options Menu & Units

The Options dialogue has been replaced with the new options menu, which is quickly accessed from the Measurement Partner icon in the top left corner. Amongst a number of new settings, the menu now provides a consistent and flexible solution to accomodate the preferences of its global users and you can set your unit preferences for calculations.

Options - Units
2 Channel Support

2-ch Support

Type 2270 users can now perform a wide range of 2 channel measurements using the 2 channel option including SLM, CPB, logging and signal recording. All changes in the instrument software are of course fully supported in Measurement Partner version 4.3.

2 Channel Support

G-Weighting and Building Vibration

The new Low frequency option for the instrument covering infrasound and building vibration measurements has added many new parameters and extends the CPB spectrum down to 0.8 Hz band for 1/3 octave. All changes in the instrument software are of course fully supported in Measurement Partner version 4.3.

BZ-5503-A Logging Module

Marker Level Exceedence

It is now possible to identify whether predefined limits have been exceeded within a marker period (for example day, evening, night). The limits and the parameters they are based on are configured by the user.

Level Exceedence Check Dialogues

Octave bands in profile

Users interested in studying individual octave band in a logging profile now can do just that by selecting the octave bands of interest.

New Look
Tone Detection Marker

Tone detection in profile

As for impulses, Measurement Partner will mark the occurence of tones in a logging profile according to criteria set in the Marker and report wizard.

Impulse Detection Marker

Impulse Detection in a logging profile

Measurement partner now includes an objective method for the assessment of impulses. Define the threshold for impulses in the Marker and report wizard and Measurement Partner will mark in the logging profile these criteria are exceeded.

2 Channel Support

Listen to Signal Recordings associated with an Marker

If you're using the Automatic signal recording setting on the instrument a WAV file will be created for the duration of the measurement. However, rarely is the whole WAV file of interest for analysis and playback. For this reason Measurement Partner now supports the playback and export of WAV files associated with individual markers.

BZ-5503-B Spectrum Module

Basic calculations on FFT spectra

Need to perform basic calculations on FFT spectra? The Spectrum license is now extended to cover not only CPB but FFT based calculations

Basic calculations on FFT spectra

Convert FFT to octave spectra

Need to compare an FFT spectrum with a CPB spectrum? Convert your FFT to CPB by simply dragging it into a calculation already containing a CPB spectrum.

Basic calculations on FFT spectra

BZ-5503-C Wave File Analysis Module

FFT Tone Analysis

FFT tone analysis

Measurement Partner now offers Tone analysis of signal recordings. Perform a signal recording in the field and analyse for tones later back in the comfort of your office. The tone analysis can be performed by selecting which portions of a WAV file you want to analyse for tones. Simply mark the portion of the logging profile and click analyse. Tone analysis can also be performed on complete WAV files from the side bar.

Other Features

BZ-5503 Export each project separately
BZ-5503 More intuitive zoom on FFT Spectra
BZ-5503-B Tone Analysis according to France NF S 31-010
BZ-5503-B Tone analysis results are now marked in the spectrum for both CPB and FFT based assessment.
