Getting Started<br />
The <strong>ER</strong>-<strong>200D</strong> <strong>Personal</strong> <strong>Noise</strong> <strong>Dosimeter</strong> is an inexpensive,<br />
easy-to-use device that provides a good estimate of noise<br />
dose and alerts the user to the risk of over exposure.<br />
In cases of gunfire and other impulse noise, no conventional<br />
dosimeter measures the risk accurately. More specialized<br />
equipment is required to measure impulse noise.<br />
The <strong>ER</strong>-<strong>200D</strong> has three modes of operation:<br />
· Status: displays the previously measured results, indicates<br />
when batteries need to be replaced, and indicates when<br />
the device memory is full.<br />
· Normal: measures and displays noise dose continuously<br />
for up to 7 days; provides an early warning for<br />
over-exposure and the need for hearing protection.<br />
· QuickCheck: measures noise for two minutes then<br />
calculates and displays the estimated dose per hour.<br />
QuickCheck provides a quick way to measure a specific<br />
noise source to determine if permissible exposure levels<br />
will be exceeded and hearing protection is needed (e.g.,<br />
loud equipment, vehicles, power tools, concerts or sporting<br />
events).<br />
