NOTE:
If the measured value is equal to the nominal
resistance of the resistor or within the range of
error, the resistor works correctly;
If there is a large deviation between the nominal
resistance and the resistance, the resistor is
damaged;
If the measured value is infinite (open circuit),
zero (short circuit), or unstable, it means the
resistor is damaged and it can’t be used.
WARNING
Before measuring in-circuit resistance, be sure
that the circuit under test has all power
removed and all capacitors are fully discharged.
Otherwise, the instrument may be damaged and
may be struck by electric shocks.
