AC volt meter is a meter switch voltage (AC VOLTAGE) using this type of meter is in principle the same as DC volt meter. Is in use, it will have to be measured in parallel with the load that must straddle the measurement voltage, it is different from a DC volt meter. Is to use the cross-voltage meter or power supply is not necessary to observe the polarity of the meter? Because the switch with voltage polarity switch at any time. AC volt meter. There are 5 districts is 0 ~ 0 ~ 10V, 2.5 V, 50V 0 ~ 0 ~ 0 ~ 250V, 1, 000V and. There are 4 of the scale is 0 ~ 0 ~ 10, 2.5, 0 ~ 0 ~ 250, 50, read the scale tick marks below the mirror.The stage using the AC volt meter.1. connect the AC volts while measuring voltage across the load. 2. set the meter's neighborhood in the heart of ACV. 3. adjust the timer to measure the correct district. If you do not know the measure of how much the maximum measuring location (1, 000V), then downgrade to a lower district, one at a time until the meter needle will point the district values that are readable and correct.4. connect the meter high voltage power switch should be turned off (OFF) of the circuit to be measured. 5. do not handle the meter when measuring or high voltage measurement. When the measurement is complete, the switch should be turned off (OFF) the power of the circuit measured before discharge gauge meter out of the circuit.
