HLS-2D Metal Loss Test Driver

Metal Loss Test Driver

Part code: HLS-2D

Easily determine the correct loop system for the room
Preset output level ensuring consistent test results
Compact and lightweight

Combined with the Loopworks Measure R1 Field Strength Meter, the HLS-2D Metal Loss Test Kit delivers a preset output level to give consistent test results. Ideal as a quick and simple site assessment tool.
The HLS-2D comes with a 12V power supply but can also be used with a suitable 12V battery. It uses efficient class D current drive technology to reduce power consumption and heat output.
It is the only truly portable loop test driver that is capable of generating test signals to the IEC60118-4 Standard. The 4mm banana output sockets (included) allow simple connection to test cables.
The unit has a 5 year warranty and free technical support.

HLS-2D Metal Loss Test Driver

Metal loss testing

Determining metal loss and background noise levels are important steps in designing hearing loop systems to avoid loss of an intelligible signal and to meet the IEC 60118-4 international standard. To correctly assess an area for metal loss and background noise a temporary loop will need to be used in either a Perimeter loop or figure of eight MultiLoop configuration, depending on the estimated levels of metal in the building structure. For this you will need a loop driver, a field strength meter, a loop cable, a signal source and a tape measure. Carrying a full size loop driver around can be cumbersome and impractical to setup every time so Ampetronic developed the HLS-2D Metal Loss Test Driver. The HLS-2D is a light, portable, loop driver with a preset output level to give consistent test results; and when used in conjunction with the Loopworks Measure R1 or Ampetronic FSM field strength meters, forms part of a quick and simple site assessment system.
