Measurement

 
While measuring, VM-STRUC displays the vibration total value and a colored assessment.
 
Measurement
1

Measuring mode

 
1. Measuring mode
Shows the used settings
2

Sensor placement

 
Shows sensor placement with regard to the building and in detail.
2. Sensor placement
Total view
 
Place the sensor at a location in the building where highest vibration is expected.
Sensor position
The X and Y axes should be oriented along the walls of the building. Adjust the Z axis vertically using the level and the adjustable feet.

Start/Stop

3. Start/Stop
Starts and stops measurement. Starting is only possible when all settings in Measurement mode menu have been completed.
4

Status bar 1

4. Status bar 1
Shows sensor and channel data.
5

Measuring values X/Y/Z

5. Measuring values X/Y/Z
Shows the peak value of vibration velocity for each direction.
6

Status bar 2

 
6. Status bar 2
Shows for each direction:
7

Status bar 3

7. Status bar 3
Shows
  •  the most critical peak value at the frequency with the highest magnitude
  •  the frequency with the highest magnitude
8

Vibration total value

8. Vibration total value
The maximum value of the three axes.
9

Measuring duration

9. Measuring duration
Remaining and elapsed measurement time are displayed. The elapsed measurement duration counts with minus sign from start delay to 00:00:00. Afterwards, the elapsed measurement duration counts up to the aimed measuring time. The measurement is stopped when it reaches the aimed measuring time.
For infinite measurement there is no display of remaining time.

Remarks

10. Remarks
Shows the current status of measurement.

Signal input

11. Signal input
At the signal input, you select the measuring channel and configure the measuring range. If you activated the sensor automatics VM-STRUC selects the measuring channel automatically.
