Preparing for Measurement
After unpacking the unit the 2xR6 batteries must be inserted. Pay
attention to the correct polarity when inserting the batteries.
However, a wrongly inserted battery will not cause any damage.
As an optional accessory, a hand strap is available to prevent the unit
from accidentally being dropped during longer measurements. Boogie
is a precision measuring instrument and should always be handled with
care. In particular, the microphone and the display are sensitive
components.
For outdoor measurements, the windscreen should be placed over the
microphone to reduce wind noise, which may otherwise produce false
measurement results.
If a calibrator is available, the instrument should be calibrated before
each measurement and ideally the sensitivity should be checked again
with the calibrator after each measurement.
Either primary cells (alkaline, zinc-carbon) or rechargeable batteries
(NiCd, NiMh) of R6 (AA) format can be used. The ultra low power
technology of the built-in microprocessor allows an extremely long
operating time with a single set of batteries.
However, the batteries should be removed from the unit if it is not to be
used for three months or longer: discharged batteries may leak and the
leaking electrolyte can cause damage to the instrument.
Operation
Function of Buttons
The instrument is switched on / off by holding the [
MODE/
POWER]
button pressed for longer than one second. After switching on, a
functional test of the display is performed, i.e. all segments of the
display are visible simultaneously for a short time.
Afterwards the instrument is in the L
p
and Autorange operating mode,
which is indicated by
AUTO
.
The measurement range can be selected by pressing the [
RANGE
]
button. The minimum and maximum values of the current range are
displayed in the bar graph.
The [
MODE
] button changes the mode. The current operating mode is
shown in the display:
AUTO
