Review on 🔧 Toughs M101 True-RMS Digital Multimeter - Auto-Ranging, 6000 Counts - Electricians Pocket Multi Tester with LCD Backlight by Junior Andreano

I've just done some testing and am very happy. The numbers are big and easy to see, but what really amazes me is the accuracy of this multimeter. I mainly use it for voltage, AC and DC. For example check AC grid voltage. My power monitor may read 120.1 and the M101 stays a step away from that 120.1. I also have M102 and it is exactly the same. When the performance monitor changes, M101 and M102 change. Up to 0.1 V. I checked the line frequency. 60.00 to 60.01 Hz. Again, these are both units. The local utility regulates the grid frequency strictly. When handling multimeters that pull down a few volts, the accuracy and precision I get is what I expected from $100+ lab quality instruments a few years ago. I don't know what Tugs is doing, but the performance is great. The backlight freezes for 15 seconds. I wish there was an on/off option. The other is in a situation where I may need to control the tension for more than a few minutes. I can turn off auto-shutoff, but I get a reminder tone. I'm new to this, so I'm not sure if it can be disabled. Nevertheless, this is a precision multimeter that will not be returned.
