What battery does volt meter check?

Trying to learn as much as I can about my new to me 2008 Rinker 330 while under shrink wrap till Spring.  Concerned about monitoring battery health when on the hook, so I'll have an idea when I need to fire up the genset.  Boat has 4 batteries: genset, house, 2 engine.  The surveyor described my battery switches as, 

"House and Generator Battery switches are Blue Sea Systems On-Off Operable.
Engine battery switches are Marine Electric Battery Switches with a Voltage Sensitive Relay Module for emergency starting. Operable."

Does the 12 volt meter in the lower right of photo measure only house battery voltage (the most important for what I want to know), or does it measure any combination of all 4 batteries, which would depend on knowing the combination of switches on or off at any given time (useful to know)?

    I am sure that others will chime in, but I would say that on that panel, it measures the house batteries. The ones at the helm measure the engine batteries.

    That's how it is with my 310, when on shore power you can see on the panel the charging bump up the voltage as expected.

    yes, it is house battery.  You can actually turn your house battery switch off and see the meter go to zero.
