The Extech Instruments 407860 Vibration Meter is designed to measure vibration levels in industrial machinery, detecting issues like misalignment, poor balancing, and structural compromises. It provides measurements in displacement, velocity, and acceleration and complies with ISO-2954 standards. However, the manual does not mention its suitability for measuring ground shaking in construction activities, which typically require seismographs or specialized ground vibration monitors. Therefore, it is not explicitly designed for construction-related ground shaking measurements.

@Mr. Anderson. It is unfortunate. I received the instrument this week, and we plan to use it for ground shaking measurements. However, could you recommend a solution or adaptation for using this instrument effectively? For instance, any specific attachments that would make it suitable for construction activities?
