When you need a multimeter for testing electrical equipment around the home, it's vital to know what all those symbols around the dial mean.

To measure a zener diode’s breakdown voltage, you need a dc voltage source whose voltage exceeds that of the zener voltage. In Figure 1, resistor R SER provides voltage drop between V IN and V ZEN. In ...

We have all had difficulty testing diodes in-circuit. Most DMM’s have a diode Vf function that measures forward drop, but what is the normal voltage drop? Analog VOM’s attempt to measure resistance of ...

While using a digital multimeter to diagnose electrical problems on customers’ equipment, I frequently hear the comment, “I’ve got one of those multimeter things, but I never learned how to use it.” ...

Fluke Corp. has introduced a new, easy-to-use utility multimeter designed to help utility workers, linemen and electricians to quickly diagnose electrical problems. Fluke Corp. has introduced a new, ...
