A.c. voltmeter voltage meter is alternating (AC VOLTAGE) main use for this type of meter is the same as the DC voltmeter. Is in use, you need to measure the cross parallel to the load to the desired pressure, it will have a different section from a DC voltmeter? Is to use a meter across, pressure or power supply is not required to observe the polarity meter. Because the voltage switch will have to switch to switch all the time. AC voltmeter All districts are 0 ~ 0 ~ 10V, V 2.5, 0 ~ 0 ~ 250V, 50V and 0 ~ 1, 000V. There are 4 scale is 0 ~ 0 ~ 10, 2.5, 0 ~ 50, 0 ~ 250 reader scratch the scale under the mirror.The hierarchy using the AC voltmeter1. plug AC volts while measuring pressure bracket parallel with the load. 2. set the meter's running neighborhood district in ACV. 3. set the switch to the correct measure If you don't know the values that will measure whether?, set the measurement at the highest position (1, 000V) first and then the downgrade to a lower district and districts until the meter needle will point values that are readable and accurate.4. before you continue on a high voltage meter should be switched off (OFF) of the circuit to be measured first. 5. do not touch the wire gauge or meter while measuring the high voltage. When measurements are done should be closed (OFF) power switch of the circuit being measured before unplugging the cables out of the meter's measuring circuit.
