Sensor placement

 
2. Sensor placement
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.

Status bar 1

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

Measuring values X/Y/Z

 
5. Measuring values X/Y/Z
 
Shows the vibration value KB_Fmax for each axis.
6

Status bar 2

 
6. Status bar 2
Shows for each direction:
7

Status bar 3

 
7. Status bar 3 
Shows for each direction:
  •  the most critical value at the frequency with the highest magnitude
  •  the frequency with the highest magnitude
8

Vibration total value

 
8. Vibration total value
This is the maximum value of the three axes.
9

Measurement duration

 
9. Measurement 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.
