How do I find out how many amps something draws?
You can usually find this information listed on the product label, or in the owner’s manual. Then you take the wattage, and divide it by the voltage (100 watts / 12 volts = 8.33 amps.) This will tell you roughly the amperage your equipment will draw.
What does 200m mean on a multimeter?
The range switch on the front of the multimeter shows the maximum current that can be measured on that range. The range switch is pointing at the ” 200m ” DC Amps range in the picture. Therefore, the full-scale readout for this range will be about 200 milliamps.
How do you check dc current with a multimeter?
How to measure dc voltage with a digital multimeter
- Then insert the red probes into the V Ω jack. When finished, remove the probes in reverse order: red first, then black.
- Connect the test probes to the circuit: black to the negative polarity test point (circuit ground), red to positive test point.
Can you measure AC current with a multimeter?
Both AC and DC currents can be measured with a multimeter by connecting the meter in series with the circuit, in which current being measured provided the current in that circuit is limited or controlled by a load or appropriate values of resistance.

How do you use a fieldpiece sc66 multimeter?
With the NCV tab on the tip of the clamp close to an AC voltage, press and hold the NCV button. The NCV LED will light with an analog feel and the beeper will beep. The closer you get to AC voltage, the louder the beep. The NCV function is sensitive enough to detect 24VAC on thermostats (24V to 600V, 50Hz to 60Hz).
