Industrial Sound Level Meter Output Connection Test.
The effect on an industrial sound level meter (ISLM) of a 10,000 decibel resistive load at the output connection is tested over the frequency range of 22.4 to 11,200 Hertz. Reference test requirements, required equipment and test procedures, calculations and analysis of ISLM readings using various voltages and connections are presented.
