Turning on/off
TURNING ON:
To switch the power on the operator should hold the
<ENTER>
key for a couple of
seconds. The instrument switches on and goes the self-test routine (during this time the manufacturer's logo,
the name of the instrument and firmware version is displayed).
Then the
SV 104IS
will run through a short start-up sequence, showing the current configuration setup
loaded along with the names of all of three profiles, followed by battery state screen. After this,
the instrument will enter the stopped (ready to measure) mode and enter the running instantaneous SPL
mode if enabled.
Notice:
Warm up time - After power on, the instrument should be warmed up for at least
60 seconds before starting measurement.
Notice:
If you leave the instrument in stopped (ready to measure) mode, the display will be
switched off after 30 seconds, and the unit will turn off after approximately 5 minutes of no keypad
activity to save the batteries.
Notice:
SV 104IS will show a warning screen if the battery capacity is below 2 hours of
potential measurement time.
TURNING OFF:
To shut down the unit the operator should hold the
<ENTER>
key for a couple
of seconds during which a countdown
(“Shutting down” 3… 2… 1… ) is displayed. Thus, the
SV 104IS
gives
you time to decide if you really want to turn off the instrument. If you release the key too early, the
SV 104IS
returns to the last presented
VIEW
mode.
If enabled in the configuration setup there may be presented an additional, double-check, warning
screen. This is for the operator to be aware and convinced the unit is really to be turned off. See figure
below:
Figure 4-2
Power-off warning screen
Notice:
SV 104IS will automatically shut down after 5 minutes in stopped (ready to
measure) mode.
Notice:
If
auto-run
(timer) mode is active,
SV 104IS
will automatically stop the
measurement when the set time is over and then turn off. If no
auto-run
mode is used and specific time
has not been preset, the unit will continue to measure until the battery is exhausted. Just before switch
off, the measurement run will be stopped and all data until that point will be saved securely for later
download to the PC.
