Environmental, electrostatic and radio
frequency
criteria
Note: In the measurement conditions with the strong electromagnetic disturbances (e.g. near the
high-voltage transmission lines) the lower measurement limit can be drastically shifted as the result
of the external field influence on the measurement cables. In such cases, the careful shielding of the
measurement cables is strongly recommended. It is worth to underline that the estimation of the
external influence can be performed in-site by the observations of the measurement signal spectrum.
Effect of humidity
< 0.5 dB
(for 30% < RH < 90% at 40
C and 1000 Hz)
Effect of radio frequency fields
(meets
requirements of the ISO 8041-1:2017)
The greatest susceptibility (the least immunity) is achieved when in the VLM the
HP1
filter is selected and the
RMS measurements are considered.
The greatest susceptibility is achieved when the VLM and accelerometer with cable is placed along field and
the cable is coil as solenoid.
Effect of electrostatic discharge
(meets
requirements of the ISO 8041-1:2017)
During electrostatic discharge, the influence of the displayed results could be observed.
No changes in instrument operation state, configuration or stored data corruption were found out.
Operating range
from -10
C to + 50
C
Storage
and Transportation
from -20
C to + 60
C
Effect of temperature
< 0.5 dB (from -10
C to + 50
C)
Operating range
from -10
C to + 50
C
Storage
from -20
C to + 60
C
Effect of Vibration
< 0.1 dB (measured at the instrument vibration 1m/s2 in the
2 kHz band)
