4.1.4 Erasing Records
In some cases, you may want to erase the last record you
saved. For example, if you took a preset interval measurement
that was overloaded and therefore invalid, then you should
erase the record and retake the measurement. (Note that this
is not necessary with an interrupted or manually timed meas-
urement, since the record is not saved automatically.)
After you have downloaded your records to a computer, then
you no longer need to store your record on the instrument.
You should erase all records on the sound level meter so that
the memory will be free for storing future measurements.
To erase the last record taken:
1. If the instrument is measuring, then press to stop it.
The Measurement Window must read
STOP (as shown in
Fig.4.6 ), not
RUN.
2. Press until the Erase Last Record Window is visible
on the screen, as shown in Fig. 4.7. The number of the last
recorded record is displayed. In the example shown,
record no. 6 will be erased.
3. To erase the record shown, press . To cancel, press
. If you press , then a warning like the one shown
