Question 1

Anybody tried testing transistors?

Accepted Answer

Yes, I have.   The hFE function measures the DC gain of the transistor when correctly inserted into the circular connector on the left of the multimeter.   You will notice the connector is split for NPN & PNP transistor gain testing respectively with connections for both the Base (B), Collector (C), and Emitter (E) of your transistor.  Be sure to properly insert your transistor leads all the way down on the correct side for NPN or PNP transistors as well as first identifying your transistors Base, Collector, and Emitter leads for proper testing.

I just uploaded a picture on the listing page shows a transistor having it's hFE DC gain tested which is measured at 349.  This is normal for this transistor and shows it functioning properly.   Common transistor DC gain may be between 50-500, but this varies greatly transistor to transistor.

The picture is not live on Amazon yet, so in the meantime here is a link to it for reference:

Also uploaded to Amazon a video demonstrating the Square Wave Function Generator Output from the PDM-711 Multimeter:

If I can do anything else or if you have any other questions just let me know.   We are a small husband and wife business and customer satisfaction is truly very important to us.

Have a great day!

Question 2

How loud is the buzzer? Most multimeters have a tiny high-pitch sound that is nearly inaudible and useless to me.

Accepted Answer

For the continuity test function on the multimeter the buzzer is audible fine for me, and I have never had issues hearing it or had any complaints about it.  Personally I find it very useful for circuit testing, but I have not used it in a very loud environment if that is what you are looking to do.  It would be hard to define without testing on a sound meter, but that said it is about the typical loudness of buzzers in similar multimeters due to the piezoelectric elements used to emit the sound.

Question 3

Does this have a warranty?

Accepted Answer

Hello!
Yes it does have a warranty against factory defects and workmanship for 90 days.  We at ProTechTrader stand by our products and are happy to help our customers with issues so do not hesitate to contact us directly at CS@ProTechTrader.com or through Amazon messaging system.

Question 4

Am i able to tune this multimeter to "%hzv", select ac mode? i'm looking into a device that would require this to see if it's working properly.

Accepted Answer

I just read the user manual... it is available with the listing.  This function is not available on this meter.
