software. Dead time correction employs first and second order
corrections for extended performance.
The front-panel setup feature can be disabled via the internal switch on
the Model 3000 in order to protect settings from inadvertent changes.
The unit is operated with four alkaline AA batteries for operation from
-20 to 50 °C (-5 to 122 °F). Battery life is approximately 750 hours
under normal usage. A low-battery indicator on the LCD warns when
less than 16 hours of battery life remain.
The Model 3000 may optionally be provided with a 1/8-inch stereo
headphone jack that would allow for headphone use for audio output. It
is located to the left of the detector connector.
