1 Introduction
Congratulations on your purchase of the Opus Suite Data Logger module.
The Opus Software Suite is a Sound and Vibration software. The current version contains six
measurement modules:
• SLM 4-ch module : 4-channels, Class 1 (IEC 61672 and ANSI S1.43)
• SLM & 3Vib module : 1 SLM channel (same as SLM 4-ch module) and 3 vibration channels
(ISO 8041 and ISO 2631)
• Data Logger module
• Building Acoustic module
• Sound Transmission (ASTM E 336/ISO 140-4)
• Reverberation Time (ISO 3382)
• Speech Privacy (ASTM E 2638 and ASTM E 1130)
• Building Vibration module (DIN 45669-1 and ANSI S2.46)
• Intensity module (IEC 1043)
The Opus Suite is intended to run on a Concerto. The software can also be installed on a computer if
an Alto-6ch or an I-Track unit is connected. Moreover, some post-processing functions are available
on a PC even if no compatible unit is detected.
The current user’s manual presents the Data Logger Module.
