With a DMM it’s okay to measure low amp draw devices such as VTX, FPV camera, or RX, but for anything that is power hungry, like motors, you should NOT use your multimeter or it might blow up the fuse. A clamp meter (buy:https://s.click.aliexpress.com/e/_DkyyHbp) is a much...
Though mosfets usually require sophisticated equipment for checking their conditions, a simple way using a multimeter is also considered effective most of the time for checking them. We take the example of two types of N-channel mosfets, the K1058 and the IRFP240 and see how these mosfets can...
How to turn your iPad/iPhone into a Digital MultimeterMax MaxfieldDesignline Editor
The multimeter seems to be a trusted tool for identifying shorts as well as other technical defects in virtually any electrical device. A circuit board can be quickly checked for capacitance, current, input voltage, DC & AC voltage, resistance, fuse shorts, with a multimeter. The tool is typi...
However, if you’re unaware whether the power rails are or aren’t isolated, it can often lead to issues while building your circuit. It’s always a good idea to use a multimeter to check for the absence or presence of continuity in your breadboard’s power rails. Providing Power to ...
Online, particularly in most of electronic forums, this multimeter method typically elicits a variety of conflicting reactions. Nonetheless, tracing the short circuit’s test locations might be quite helpful in identifying the issue. The multimeter you use in this situation needs to be milliohm sensit...
The two strain relief screws must be tightened to secure the flex. Make sure you tighten it on the outer sheath, not the inner cores. © Eugene Brennan How to Check the Fuse in a Plug You can check whether the fuse in a plug is ok using a multimeter set to the continuity range. ...
We especially like the way he shows how to test whether or not the unit’s thermostat is working, using a multimeter’s continuity tester and an ice cube. Note, though this video discusses fixing a refrigerant leak and dealing with the unit’s compressor, both of which are beyond the scop...
Multimeter - Best to get one with a diode test mode to look for shorts. Fine Tipped Test Leads - Get some that are really pointy, like "stabby" pointy. Then put something on the tip to protect them (and you) while storing them. ...
This is the circuit diagram of the test board. Current can be measured by connecting the multimeter in series at any part of the circuit. For convenience, the probes are connected closer to the battery. This will help measure current when any or all of the switches are turned on. The bla...
