Page 2: Meter Description
Introduction Congratulations on your purchase of the Extech 407860 Vibration Meter. The Model 407860 measures vibration levels in industrial machinery. Misalignment, poor balancing, structural compromises, and other factors can cause unwanted vibration increases. The Model 407860 has a frequency sensitivity that meets ISO-2954 and offers Displacement, Velocity and Acceleration features. -
Page 3: Meter Operation
PEAK – For measurement of the peak value. Not available in the Displacement mode. MAX_HOLD – Holds and displays the maximum value. The display will update only when a new maximum is measured. Not available in the Displacement mode. 407860-EU-EN v2.7 3/14... - Page 4 Turn the meter on and set the function to ACC and RMS. Make sure the vibration sensor is perfectly still (no vibration). Press and hold the HOLD button for > 5 seconds to allow the display to reach the zero value. 407860-EU-EN v2.7 3/14...

Questions and answers
This model can be used in construction activities to determine the ground shaking?
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?
