V has a straight line. AC voltage (like what comes out of the wall) can be dangerous, so we rarely need to use the AC voltage setting (the V with a wavy line next to it). If you're messing with AC, we recommend you get anon-contact testerrather than use a digital multimeter. ...
Outlines how the Tektronix Inc.'s TekMeter digital multimeter works. Conversion to a dual-channel realtime digitizing scope; Function of the scope to continuously track waveforms; Circuitry of the scope in a single application specific integrated circuit (ASIC).EBSCO_AspComputer Design...
Moreover, a digital multimeter is great for various electric works with a high-resolution screen and ability to measure millivolts. On the other hand, a clamp meter only measures current up to the nearest tenth with premium clamp meters having the capability to measure up to the nearest hundr...
There are typically four problems that can occur with the tach:it is totally inoperative and always displays zero; the needle is stuck or permanently pegged; the needle is erratic; or the RPMs are consistently off - either low or high. To test the tachometer, you will need a digital multi...
In the article How Boolean Logic Works, we looked at seven fundamental gates. These gates are the building blocks of all digital devices. We also saw how to combine these gates together into higher-level functions, such as full adders. If you would like to experiment with these gates so yo...
Learn how your meter works and save on your power bill. Also further your career as a meter tech or lineman by learning more about how meters work.
Before breaking your circuit to connect it to your digital multimeter, ensure that it works on its own. Break the circuit at any point and connect the two probes to the two open points on the circuit. Press the trigger key and hold the probes to your circuit for two seconds. Then discon...
One of two types of regulators are found in most alternators: The grounded regulator works by controlling the amount of negative or battery ground going into the winding in the rotor, while a grounded field type works the other way around — by controlling the amount of battery positive. Neith...
There are a few simple steps required to make a resistance measurement with a digital multimeter:Select the item to be measured: This may be anything where the resistance needs to be measured and estimate what the resistance may be. Insert the probes into the required sockets Often a digital ...
We take the example of two types of N-channel mosfets, the K1058 and the IRFP240 and see how these mosfets can be tested using an ordinary digital multimeter through slightly different procedures. How to Check N-Channel Mosfets 1) Set the DMM to the diode range. ...
