One application that uses a precision power supply and DMM involves characterizing the current drawn by a device or circuit board at different voltage levels. Figure 1 shows a typical setup. Engineers ...

How to effectively measure ultra-low bias current by recreating the measurement scheme from an app note. Measuring input capacitance and input current. Creating a better measurement environment. 3. Cp ...

I'm having problem with a starter motor on a riding mower, and need to check if the motor is getting juice and not working or if something else isn't working and no juice is getting to the starter.

Measuring AC current (220-V mains RMS current) is not as simple as measuring DC current. In DC current measurement, you can simply hook the oscilloscope probe to the shunt resistor and calculate the ...

Is it possible to use a DMM to verify that a circuit isn’t hot, and then get shocked anyhow? Yes, and you need to make that impossible. Here’s how you do it. First, understand why the DMM might not ...

Santa Clara, Calif. — Agilent Technologies Inc. has introduced the U2741A USB modular digital multimeter (DMM). Roughly the size of a paperback book, the 5.5-digit U2741A DMM is the latest member of ...

We would like to share a bit of good news; Collin’s Lab is back on the airwaves of the Internet. If you didn’t know, [Collin Cunningham] previously created excellent short videos, sometimes ...
