3.2.2 Taking Preset-timed Measurements
To take a preset-timed measurement, the preset time must
be set to a specific interval (not “Off”). See section 3.4.3 for
more information about making this setting.
1. Press to switch on the instrument. (If the instrument
is already switched on but not measuring, then press
and skip to step 4.)
2. Wait for the sound level meter to start-up (about 8 sec-
onds). This gives you time to step away from the instru-
ment if required.
3. Measurement begins automatically.
4. Measurement will stop automatically after the preset
time interval has expired. All measured parameters will
be saved in the next available record (see section 4.1 for
more information). If there are no records left, then you
will see a warning on your screen (see section 4.1.2).
5. Check the upper limit of the measurement range, if it is
blinking, then an overload has occurred and the meas-
urement may be invalid (see Fig. 3.3). If an overload has
occurred, then increase the measurement range by press-
ing . You may want to erase the last record of the
overloaded measurement as described in section 4.1.4.
Begin a new measurement by pressing and repeat
from step 4.
6. Step through the displayed measurement parameters by
pressing . If some of them show no value (---.- dB),
then input levels were too low for the measurement range
(under range). If necessary, decrease the measurement
range by pressing once or twice (check the measure-
ment range on the screen as shown in Fig. 3.3). You may
want to erase the last record of the under ranged meas-
urement as described in section 4.1.4. Begin a new meas-
urement by pressing and repeat from step 4.
