5.4 Parameter: Group 2
Mode 1 Code number
Value: 22
Mode 2 Sensor sensitivity
Default value: 100 mV/mm/s
At the same time the sensitivity of an acceleration sensor is selected, the
integration for conversion of vibration acceleration to vibration velocity is
activated.
Selection Value Sensor for Requirement
1 70 mV/mm/s v
2 100 mV/mm/s v
3 100 mV/g a -24 V
4 10 mV/g a + 4 mA
5 100 mV/g a + 4 mA
6 10 mV/g a -24 V
Meaning: a = Vibration acceleration
v = Vibration velocity
Mode 3 Correction factor
Default value: 1.00
To allow sensors which have a sensitivity other than those listed in parameter
2 of Group 2 to be used with the instrument, the selected value can be
corrected with a factor in the range 0.1 to 1.99.
Mode 4 DC Current output range
Default value: 4 … 20 mA
Selection Range
0 0 ... 20 mA
4 4 ... 20 mA
