– First, turn off the power supply to the circuit and let it cool down for safety purposes. – Set your multimeter to diode mode (usually indicated by a diode symbol). – Connect the red probe (positive ...

Here is a handy zener diode tester which tests zener diodes with a Digital Multimeter with breakdown voltages extending up to 120 volts.

From this virtual multimeter, a diode characterization system was developed by applying a current and voltage measuring circuit when forward biased. The current and voltage measurement data are ...

DMM test functions include low-impedance (LoZ) mode, temperature (Type-K thermocouple), and extended voltage measurement range up to 600V. It can measure ac/dc voltage, current (A, mA, μA), frequency, ...

A multimeter is a helpful tool for advanced electrical projects. But multimeter symbols and their meanings can be cryptic to a new user. Learn what multimeter symbols mean, how to connect the ...
