9. Input Voltage Measurement
In this section:
The GlobalLink measures the voltage on its own power connector. If none of the connected VE.Direct or Smart devices is able to measure voltage, this value is used instead in VRM.
Note that this measurement is not very accurate. At 14V it's +/- 0.2V, at 24V it's +/- 0.5V and at 48V it's +/- 1V.
