Operating mode and position that
produces
the maximum
susceptibility (minimum
immunity) to irradiated fields or
conducted through the power
supply
Normal* operating mode of the vibrometer
according to the accelerometer used
(AC031, AC032 or AC033),
VC431 in the
upright position, with the main axis of the
equipment perpendicular to the direction
of propagation of the field with vertical
polarisation. With all the cables connected
and powered through the PC.
The equipment fulfils the basic specifications of the ISO 8041 Standard for the
required immunity to alternating current power and radiofrequency fields
The equipment shows no degradation or operational loss after exposure to
electrostatic discharges
*
:
Normal operating mode is regarded as when the application (hand-arm, whole body or building)
corresponding to the accelerometer used (AC031, AC032 or AC033) by the vibrometer is used:

Triaxial accelerometer AC031 for the Hand-Arm application

Triaxial accelerometer AC032 for the Buildings and Structure application

Triaxial accelerometer AC033 for the Whole Body application
