DVOM vs. DCA for forward voltage (answered)

[brd]

Hi All,

My Fluke DVOM gives lower measurements when testing diodes than my Atlas DCA. I am assuming that is due to different test voltages. Which is the preferred measurement when looking for a specified vf. i.e not matching diodes.

Different multimeters and component analyzers use different test voltages and currents when measuring diode characteristics.

The Atlas DCA-55 is specifically designed for testing and analyzing semiconductor devices, including diodes, transistors, and more. For matching diodes, especially if precision is important, the Atlas DCA-55 is the better choice. It is designed for this purpose and will provide consistent and reliable measurements of the forward voltage drop.
