Working Principle
There is a constant current source in the instrument that can supply
DC current. When measuring resistance, constant current be fed into
the tested object from terminals I +, I-, then which will yield voltage in
the tested object, the value of that voltage retake to the instrument at
terminals V +, V, after amplification, the display will show the resistance
value using four and a half bits LCD digital.
