Used to measure DC current, DC voltage, AC voltage and resistance, etc.

1. Measurement of DC current

2. Measurement of DC voltage

3. Measurement of AC voltage

4. Resistance measurement

When measuring resistance, a battery needs to be connected. The smaller the resistance being measured and the larger the current, the greater the angle of deflection of the pointer.

Notice:

(1) Before measuring, short-circuit the “+” and “-” terminals to see if the pointer is pointing at zero. If not, adjust the zero adjustment potentiometer for correction.

(2) Never measure resistance on a live circuit. After use, turn the conversion switch to the high voltage position.
