Before you turn the instrument on
There are only a few things to remember:
Make sure the microphone is properly fastened onto mounting head before turning on the
instrument.
When in use for a measurement run, always use the
SA 122
windshield provided.
Notice:
Warm up time - After power on, the instrument should be warmed up for at least
60 seconds before starting measurement to allow the internal circuits to stabilise.

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
SV104
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 104 will show a warning screen if the battery capacity is below 2 hours of
potential measurement time.
