:: : Use the multimeter to measure the voltage between each of the wires ( one at a time ) to " ground ".
42.
If you have a multimeter, you can probe the power supply " outputs "-which should be 12 and 5 volts.
43.
Isolation resistance measurements may be achieved using a high input impedance ohmmeter, digital multimeter ( DMM ) or current-limited Hipot test instrument.
44.
At the very least you need someone with the knowledge to use a Multimeter for talk ) 23 : 04, 14 January 2010 ( UTC)

For example, a very low cost multimeter with a sensitivity of 1000 ohms per volt would draw 1 milliampere from a circuit at full scale deflection.
46.
If too many lights burn out however, a shunt will also burn out, requiring the use of a multimeter to find the point of failure.
47.
You may need to get creative about how you connect the multimeter to " ground " as the outlet box itself may not be " grounded ".
48.
The tests with the movement of the multimeter tubing were not been successful, showing it was impossible to create geometrically correct extended slots with moving tubing.
49.
Portable instruments, usually equipped to also measure current and resistance in the form of a multimeter, are standard test instruments used in electrical and electronics work.
50.
The upper end of multimeter measurement ranges varies considerably; measurements over perhaps 600 volts, 10 amperes, or 100 megohms may require a specialized test instrument.
