First be sure to have it on, And on the 12volt setting (if selectable) Be sure to get a good grounding point, I.E, door hinge, Seat bolt, Batt ground, Then just touch the other end (Red) to the point your testing volts. It should then give you your reading, Just be sure not to confuse the wires, Damage your testing unit or worse, Short cars wiring. Hope that helps!
Answer 2:
An ammeter needs to be connected in series with your circuit, (that is, all current must "check in" at the ammeter). Many ammeters are called multimeters because they are both ammeters (measuring current) and voltmeters (measuring voltage). many people make the mistake of setting the multimeter up such that it is reading voltage when they desire to read current.
When a voltmeter is hooked up in series with a circuit, the fuse within the voltmeter may break, sufficiently pissing off any lab instructor you may be working under.

∙ 16y agoMany multimeters have an ampere scale. The basic idea is that the current has to go through the meter in series with a load. ( meters have a fuse for the forgetful). If there is no ampere scale, put a small value precision resistor (like a 0.01 ohm 5-20W)in series with the load and measure the voltage drop across the resistor. Let's say the voltage across the resistor is 1 Volt, then 1V/0.01=100 Amps.

What instrument is used to check the full load amps of a compressor?
amprobe
Explain the power rating of this bulb say 60W what if the voltage changes?
You can check it out yourself using these formulas. Watts = Amps x Volts. Voltage = Watts/Amps
How do you convert micro amps to amps?
The prefix 'micro' means, one millionth. So there are one million micro amps in one amp
How many watts in a 115 volt refrigerator?
How many Amps is the fridge pulling? Multiply the Amps by the 120V circuit you're plugging into and you'll get your Watts.
What will happen if a phase and neutral test by a mutimeter shows continuity?
If the test shows that there is a continuity between the phase leg and the neutral with no load connected, then that circuit should not be energized. If the circuit was energized then the fuse or breaker protecting that leg will trip the circuit open.
How do you confirm that you are not overloading an outlet?
Check the number of amps that your circuit can handle. You should not put devices with more than that many amps (total) on that circuit. Most houses are 15 amps and bathrooms 20 amps.

You just bought a 1997 Saturn sl1 and the tail lights and dash lights are no longer wooking after you gave it a car wash please help?
chances are it is a blown fuse. Look under the dash, look for the fuses cover and check the park/lamp fuses. Or check one by one and replace the blown one with another OF THE SAME CAPACITY (AMPS) ... there are 10 Amps, 15 Amps, 20 Amps and 30 Amps ... install only the proper AMPS fuse.
How many amps does 7.5 ton Air Conditioner draw?
You have to check the label on the unit itself. It will give you all the information as far as maximum and minimum amps.
Explain the power rating of this bulb say 60W what if the voltage changes?
You can check it out yourself using these formulas. Watts = Amps x Volts. Voltage = Watts/Amps
How do you tell if the compressor is bad in a window air conditioner?
Borrow a clamp on amp meter and check full load amps. If pulling full load amps then compressor condemned.
Why instrument cluster speedometer tachometer oil pressure on Ford Probe 1997 2.0 sometimes work but sometimes do not work?
loose wire or fuse.or Dash was off and ground was damaged (fuseable link) start at the fuse box and work your way out with a mutimeter. Check all grounds.
How do you test a stator?
With a mutimeter test between each lead (usually yellow in color), the reading should be approximately one (1) ohm. or close.
Can a 75 and 78 battery be used in a 94 astro van?
as long as the cranking amps are the correct stye it will tell the cranking amps on the battery check your owners manual for the cranking amps for your van or call an auto parts store and ask them what size you need.
How many amps does it take to start a SUV?
usually around 600 amps, but it depends on the engine you have. For example, a larger engine will require more amps than a smaller engine. a typical 5.0 L V8 requires about 650 amps, and some SUVs have larger and smaller engines. So check your engine,and get the right battery.
Battery is fine but cold cranking amps are low and car hesitates when cranking?
check battery and alternator
What are my options for models of 900 watt car amps?
Rockford Fosgate offers a great selection of 900 watt amps. You can also check reviews on the Kenwood 900 watt mono channel amp.
