Unique resistance being measured, according to the current through the resistor, and double make the measurement more convenient operation;
Stable performance, easy reading;
To measure resistance and current measurement;
Use of simple operation, are directly under any resistance range and testing voltage reading display Numbers as a result, the bother of should be multiplied by a coefficient, makes the measuring high resistance as ordinary resistance is measured with a multimeter sample is simple.
