measuring resistance:
Sometimes the resistor value and measured resistance
differ. This is due to the meter's output test current goes
through all possible paths between leads.
For low resistance measurements, short the test leads
and record the resistance displayed. Then connect to
the circuit and subtract the recorded resistance from
the measurement for the most accurate results.
When leads are disconnected or measurement is out of
range, "OL" is displayed.
