Before getting started, it’s important to read your digital multimeter’s manual to ensure you understand how to safely use your specific model. Below are the basic steps for using a digital multimeter to measure current. Plug the appropriate test leads into your digital multimeter. These test...
However, sometimes less ordinary situations arise and you'll find yourself out of luck: for example, a cheap 3.5 digit meter will normally have a lowest current range of 200 uA full scale. What can be done?Jo BeckerElektor electronics worldwide...

Ultra-precision, high-side current sensing is crucial in applications where one must measure the current entering or leaving a battery. Today many digital multimeters feature four-lead Kelvin sensing to eliminate the series resistance of the multimeter leads and give an accurate voltage drop across a...
The motor should be turning now, if not power everything off and recheck your wiring. Use a multimeter to measure the motor coil resistance if there is any doubt regarding the wiring. Also, make sure that the motor polarity is correct or the coils will be out of phase. ...
This is significant as the expected sleeping current of the MSP430 plus the CC2500 radio amounts to only 1.3 µA (900 nA [MSP430] plus 400 nA [CC2500]) *, a magnitude of ×1000 less than the displayed sleep current. * Verified as within range using a multimeter in series with the...
oscilloscope is used to verify the working frequency (OWON SDS5032E, Zhangzhou, China). Cooling fans was fitted around the transducer to cool the system. Voltage amplitude was measured using a multimeter (Fluke, Everett, WA) with constant gain input and frequency to determine the ultrasound ...
3458A Multimeter Component Level Repair Manual HP3458A Prototype #74 unit history, in memory of George Hnatiuk Before we go deep into hardware and measurements I’d like to dedicate this project in memory of George Hnatiuk whom we lost on September 12, 2022. George was one of the key Hewle...
Is there an adjustment I need to make, or am I missing something in the setup? I measuring the differential voltage between Copper sulphate half cell and reinforced steel in concrete where i connect my negative terminal of the multimeter to half-cell and positive terminal to the rebar. I am...
To test the circuit, the following apparatus was used. A transformer which has a 13-0-13 Tap A 4Ω 20W speaker as a load Meco 108B+TRMS Multimeter as the temperature sensor And my Samsung phone as an audio source As you can see above, I have mounted the temperature sensor of the m...
