Troubleshooting: Power Sources
Power Sources
The monitor can be powered from its two batteries, TRAM power or by an
external AC power supply. It automatically switches power sources as
they are depleted or removed.
The monitor uses the following pattern to sustain power:
1. The monitor’s external power supply.
2. The monitor’s battery power.
3. The acquisition device’s power.
It uses the internal battery with the lowest capacity to power the system
first. It only uses the acquisition device batteries to power the monitor if
there are no internal batteries or the internal batteries have capacities
too low to support proper operation.
The monitor also provides power to a acquisition device via its battery
power or external AC power source.
