Review on Borbede 168A Mini Portable Digital Multimeter: Accurate DC AC Voltage Current Capacitance Resistance Testing with NCV & True RMS Diode Tester by Unm Weil

. I have compared the accuracy of a Borbede BD-99 19999 (4.5 digit) voltmeter (this meter) to a WGGE 9999 digital multimeter using a Rigol 5.5 digit multimeter. In most cases (DC voltage, resistance, and capacitance), this $50 meter is less than the $15 WGGE. Only when measuring the effective alternating voltage did this measuring device surpass the cheaper WGGE. I improved the meter's accuracy by repeatedly rotating the dial in all ranges to "clear" the contacts. When the gauge first arrived some of the areas didn't work at all until I did a "cleanup". Accuracy improved significantly after I performed this simple operation. As another reviewer pointed out, the 19999 bill is nonsensical unless the internal electronics take advantage of those values. This meter just isn't that accurate, and it's actually less accurate than the accuracy ratings given in the manual. You need to duplicate the error reported to get closer to the truth.
