My old ULI for MAC has inputs for two voltage probes. Can I use two
probes simultaneously? For example, is it possible to use probe-1
between potentials of 0 and 4 volts and probe-2 between 5 and 9 volts?
I am affraid to try because negative inputs of two probes can possibly
be connected to a common reference or ground inside ULI. Are two inputs
really independent? I have no electronic diagram of ULI.
