Models SE and DL
Size - 7.9 cm(W) X 28.2 cm (H) X 4.1 cm (thick); (with preamp and microphone)
3.1"(W) X 11.1"(H) X 1.6" (thick) (with preamp and microphone)
• The width is measured across the face of the instrument. The length,
which includes the preamplifier but not the microphone, is measured
along the longest axis of the instrument.
Weight - 0.54 kg (1.2 lbs), including batteries.
Tripod mount - Threaded insert on the back of the instrument. Accepts a
1/4"-20 screw.
Electrical characteristics
While the instrument is operating from battery or external power it conforms
to all applicable tolerance limits of the stated standards. While operating on
battery power alone the instrument will automatically shut down when the
battery power is depleted. The total battery voltage range is between the
maximum overcharge voltage of the NiMH cells 6.6 volts and the low voltage
automatic shut down voltage of 4.4 volts.
Power sources
Internal power
Approximately 8 hours of continuous operation at normal mode of operation
under reference environmental conditions when full capacity batteries are
installed.
Main batteries - Four, replaceable alkaline AA batteries included as original
equipment. Rechargeable NiMH batteries available as an option.
• Battery life (Constant run without backlighting) - Varies greatly
depending on whether alkaline or NiMH batteries are in use and the
logging configuration. You can expect the longest battery life when
using rechargeable 2700 mAH (or greater) cells. Battery life is slightly
shorter in units that contain either filter option.
• Battery life (Constant run with backlighting) - Will reduce battery
life by approximately 10%.
Auxiliary battery - Internal battery protects against loss of settings when
the main batteries are being replaced.
