Auto Power Off Function
The instrument is provided with the Auto-PowerOff function that switches automatically off the in-
strument after 5 minutes when it is in STOP and no key is pressed in this time interval. Before
switching off, the instrument will make a series of beep: in this phase you can press a key to prevent
the instrument from switching off.
The function can be disabled from the MENU via the "Auto-Power-Off" item (MENU >> Instru-
ment >> System >> Auto-Power-Off = OFF). In this case, the battery symbol flashes to remind the
user that the instrument will not switch off automatically, but only if the <ON/OFF> key is pressed.
The
Auto-Power-Off function is temporarily disabled when an external power supply is used or
when the instrument is recording or running a program.
