Before starting to use Ohm Meter on an ADALM1K board, I tested the open circuit (or channel) resistance first. Instead of obtaining a large resistance (upward of 200kOhms), the board I am using indicates measured open circuit resistance only around 700 Ohms (at test voltage 5V). The measured Ohms stayed the same at 700 Ohms even when connected to a known resistor.
How can I fix this problem? Have I managed to short circuit some parts of the board?
