Using a multimeter



Online I've seen more simpler multimeters that you choose what your measuring. How do I use a multimeter like this for measurement

Answer



As expected this multimeter will allow you to measure voltages, currents and resistances. To do so you just need to consider basic electronics. That is consider what reading you expect to read (if it is a small or big voltage for example) and select the closest setting. You will need to connect two probes considering black probe is ground.


Be careful that the reading does not alter the circuit. For example reading a voltage requires some small current flow (for the resistance of the voltmeter is considerable but not infinite), though this should not affect circuits unless it contains small currents due to similarly high resistances.


Also, be aware of your probe configuration when taking measurements. For instance, if you are using the multimeter above, you don't want to be measuring a current potentially above 200 mA when you are plugged into the COM and \$V\Omega mA\$ terminals.

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
