TestHelper TH77 Multimeter Calibrator Multifunctional Review

This product is a huge disappointment .After purchasing it, I found a ton of issues with the accuracy of its measurements. Through trial and error, I found that it consistently gave incorrect readings. And the worst part? It's not even affordable. Why waste your money on a tool like this when there are much better options available in the Tools and Home Improvement category?

As my tests showed, this multifunctional calibrator quickly and accurately measures various electrical signals. the easy-to-read display and intuitive interface make it a breeze to use. The ability to calibrate different types of meters also saves time and effort. The only downside is that it is slightly bulkier than some other models on the market. Overall a great investment FOR any electrician or gadget lover..

Fuse blown Loop powered circuit simulates 4-20 mA and all loop functions disabled. What's the point of having fuses that don't protect anything? Now the instrument only works as a regular multimeter with automatic switching.
