In this video we take a look at the Kaiweets ST120 Pen Type Digital Multimeter. This unique form factor tool is available from Kaiweets for $21.99 (https://kaiweets.com/collections/multimeter/products/kaiweets-st100-smart-pen-multimeter-digital-voltage-tester-dc-ac?variant=41784226611377)
Like all modern meters, this one is based on a single ASIC implemented without a case directly on the pcb. Thus like all modern meters it will read trending higher, or lower depending on trimming but it will be consistent. This is full function DMM but lacks the NCV testing that it advertises.

HEY YOU ABOUT TO POST SOMETHING STUPID:
Yes, I know my hands are large/fat. It's because of a heart condition I suffer from called Congestive Heart Failure. Here's a link to some information about CHF: https://cle.clinic/2TdS2Ux
One of the symptoms is that it causes fluid retention, mostly in the hands, feet/ankles, and face..
