I am trying to build pressure sensors with Linqstat film but I don't know how to interpret the resistance's values I am reading on my digital multimeter.
Whatever the range I choose (up to 20 Mohms) the displayed value is 1. Does it mean the resistance is always bigger than the highest range or that it is always smaller ? I am sure the multimeter is OK because I have checked it with a resistor before.
Yes, or your DVM/leads are bad.
When you short the 2 leads together do you get a very small reading, less than an ohm?
