UNI-T UT131D calibration
« on: August 27, 2023, 11:00:40 am »
Is it possible to calibrate a UNI-T UT131D? On all voltage ranges it displays approx. 0.5% high. It's still within spec (on some ranges at the very edge), but slightly annoys when a cheaper Mastech M832 gives more precise readings.
PS, does this device have any hidden features?

Even more, it is systematically low (up to 1%!) on low resistance ranges, e. g. 990..991 Ω for a 1 kΩ 0.25% resistor that reads 999..1001 Ω on a new Aneng AOS02.
