Do you know whether you have delta or wye wiring?
CommentThe above answer should read 'between any two lines' and 'between any line and neutral'. There is no such thing as a 'phase' conductor!
Mine can measure 1000 volts. After that special insulated test leads are needed to protect the operator.
Yes. If voltage leads the current, the impedance is inductive (this would be the case if the load is a motor). If current leads the voltage, the impedance is capacitive (this would be the case for a CFL light bulb).
Pull the radio and make sure all the connectors are still connected to the radio, second try to determine which leads are power and ground and measure voltage on the leads coming to the radio, if you have voltage and it still will not power up after reconnecting, then consider replacing the unit if no voltage exist follow that backward toward the power source. Make sure key is in the correct position to have power available at the radio.
From line-to-line (any two of the three leads) voltage or 'line voltage', the voltage is 208 V. The line-to-neutral (one of the three leads and the neutral conductor), or 'phase voltage', is 120 V.
I would imagine that reversing the leads would rectify that. (No pun intended.)
Sounds more like you're trying to measure resistance...
A: Current flow only one way form positive to a less positive point. However it is possible to measure negative and positive voltage drop it the meter leads are reversed.
look at the multimeter! it has TWO LEADS touch them either side of the part you want to measure! wow I'm sure you could have answered that one yourself if you bothered to look at it!
Batteries are a voltage storage device that hold a voltage potential until used. By using a volt meter you can find the stored voltage by placing the leads of the meter across the battery's positive and negative terminals.
The voltage drop across a relay coil will be the same as the coil supply voltage. If you are trying to see if the coil is good or not, remove one of the voltage supply leads and check for continuity by using an ohm meter across the coil leads. A reading will tell you that the coil is intact and not open.
Make sure that the test meter is on the correct voltage scale. Place one lead on one of the conductors to be tested and the other lead on the other voltage source conductor. The reading you obtain will be the voltage potential between the two conductors.
The current leads the voltage by 90degree....
