FNIRSI® TMP-600 / TMP-610S Digital Multimeter 60,000 Counts TRMS – TMP-610S 3-in-1 with DSO DDS & Bluetooth App

Can still be improved with firmware updates

It's a great affordable product and the quality feels nice overall, i also love the case it comes with. The TMP-600 is very responsive and decently accurate for my need. Giving it 4 stars just because of few minor issues. 1. Some readings (at least when i tested in ohm) don't work in auto range and needs to be selected manually which is annoying. 2. The diode/continuity beep is very very loud but the downside is you can't lower it in the settings, adjusting the volume has no effect on the diode/continuity beep, it only works for the touch screen beep. 3. No PC Windows app support is a shame. 4. I hope Fnirsi sees this and keep improving this device with future firmware updates. A bonus if they start selling tempered glass screen protector for their touch screen products. Aside from these minor issues, i haven't experienced anything wrong with this device so far..

Excellent Feature rich equipment that is rugged and functional

I have had several Fnirsi items- the tweezer LCR, the 2C53A and the TMP610S. I have enjoyed using them all. They are feature rich, rugged, and tough. The tweezers feature a very good display, voltage protection and right/left handed operation. the 53 is a very good general purpose "lab in a box". It is almost all a beginner would need. Mine was a bit off on volts and ohms. The 610 is outstanding. The form factor, screen and operation are unlike any other meter and make it easy to read, easy to set up, and quite accurate. It is a little more money than other units, but to me, worth it. I would like to have a way to calibrate the voltage and ohm accuracy on the 53 and 610. I am a retired metrologist and radio ham that recommends test equipment to other hams and these meters are featured when I give presentations.
