Power Source Priority
1. AC line voltage supply
2. *External DC supply
3. Internal battery
*Option 78/HS only: An external 12 V
DC
source can charge the internal battery as well as
power the instrument in normal mode. The bat-
tery is also being charged when the instrument
is connected to AC line power.
This means that you can get double UPS
backup security in case of AC power break-
down, provided an external DC source is also
connected.
