The ALS-2 Ambient Light Sensor Calibrator provides a quick and simple method of verifying the performance of the ALS-2 in the field.

The requirement to regularly check the performance of ambient light sensors (also referred to as background luminance meters) used in aviation systems can be costly and time consuming if the sensor must be removed and sent away for testing. The often used alternative of observing a change in output when the window is blocked cannot be considered to provide a reliable indication of performance in an aviation system.

The ALS-2 calibrator has been designed to reduce operational downtime to the absolute minimum whilst ensuring that the ALS-2 under test is both operational and correctly calibrated. It is simple to use by non-specialist staff and comes supplied in a rugged carry case with battery charger and instruction manual.
