On the test bench, CDV-700's etc. are fitted with a temporary quick disconnect (5.5 X 2.1, pin+) for their "Battery" power input.
The ENi CDV-700 normally operate from a two D-Cell Dry Battery, but on the test bench, we use a regulated DC Power supply, which in turn supplies an in-line 3.3V AMS1117 regulator module. Metering of Voltage and current are done by in-line instruments, as needed. The same 3.3V regulator is used for all CDV-700 tests to keep the measurements of different '700's etc.?constant and relevant over time.
Also, the boards are removed from their cases, for I/O, testing, and photographing in a simple jig
