Measuring DC voltage
DC voltmeter is DC voltage meter (DC VOLTAGE) to DC volts DC voltage. Must be connected to the DC volt meter across parallel to the desired load voltage. The polarity of the DC voltmeter to the measured across the load. Must have the same polarity, the voltage drop across the load. The principle is as follows: Near positive to negative to positive in negative pressure load pins are in the positive (+) of supply is the positive (+) of the DC volt meter. Load any leg pressure near the negative (-) terminals of the power supply is used, negative (-) of a DC voltmeter to measure
DC voltmeter has 7 neighborhood is 0.1 V, 0.5V, 2.5V, 10V,. 50V, 250V and 1,000V
to 3 scale is 0 to 10, 0 to 50, 0 to 250 scale reading scratch beneath the mirror.
