PHYSICAL DESCRIPTION
The VPX-WR is a cylindrical instrument with the sensor located in a sensor horn at one
end of the instrument and the control and multifunction connector at the other.
It is covered with a ground rubber grip to prevent the slippage of the instrument when the
user has greasy hands.
The sensor horn shown in the figure above, left, houses the sensor and provides with the
threads a mounting to attach the horn restrictor which is used to collimate the sound to
narrow the field of view to help isolate the location of the leaks as well as to support the
touch probe and the waveguides.
The rear of the instrument has the control, the multi-pin connector and the power
indicator. A steady light indicates the instrument is ON and when flashing indicates a low
battery. The connector is used to charge the VPX-WR, to connect the headset and for the
optional output cable.
