Experiment 1 :DC Voltage Measurement
Theory
Generally, in case of DC voltmeter, the FS(Full Scale) sensitivity of current meter is usually from 50 A to 1mA, and its internal resistance is around 100Ω ~ 1KΩ. When the input voltage is VT, the voltage of voltmeter V1, the voltage of multiplier’s both ends V2, VT=V1+V2. And if the internal resistance of voltmeter is Rm, and the resistance of multiplier is RM, V1 and V2 can be expressed as the relational expression below.
Therefore, if the voltmeter indicates V1 value, the actual measured voltage can be earned by multiplying the magnification of measuring range.
Experiment Process
1. In M01 Module, connect between V1 of Variable Power, COM terminal and High, Low terminals of Multimeter and compose a circuit as in fig.1-2.
2. Record the measured voltage at the voltmeter in the relevant column of table 1-1 when changing the output voltage from power supply as 5V, 9V, 12V, 15V, 20V.
