Measurement of light pressure switch
.AC voltmeter is pressure meter power switch (AC VOLTAGE) principle, use the meter of this kind. Is the same as the DC voltmeter. Is in use must be applied to measure across parallel to the load to measure the voltage.Is in use the meter measure across the voltage or power supply need not consider the polarity. Because the voltage polarity switch will switch to switch all the time!AC voltmeter with all 5 area is 0 ~, ~, 2.5V 0 10V 0 ~, and ~ 250V 50V 0 0 ~ 1 000V
A, 4 scale is 0 ~, ~, 2.5 0 10 0 ~ 50 0 ~ 250 read, tick scale under the mirror.
