Digi-3-Coder (Issue 1.2)
Digi-3-Coder Airbourne Noise Emissions
Comprehensive tests have been carried out with the Digi-3-Coder fitted in a standard printer
frame and mounted onto a typical label applicator. Measurements were taken at 1.6 metres
above floor level and 1 metre away from the printer in all directions.
The measuring equipment used for conducting the tests was a Digital Sound Level Meter,
Type d-1405E supplied by Lucas CEL. Before the tests were carried out, the instrument was
calibrated and fitted with a foam windshield.
The results shown are based upon a standard type application for the printer, the operating air
pressure was set at 6 bar and the flow restrictors correctly adjusted.
The noise levels shown below are the equivalent continuous "A-weighted" sound pressure
levels in decibels "dB(A)".
