Of the downloaded firmware, could you tell me if the XT1_ZOYI_108_113 firmware was fully installed? My multimeter installs version 1.0.8, but the transistor tester doesn't, showing version 0.0.0. The XT1_ZOYI_110_116 firmware is fully installed, but the DC voltage auto measurement mode behaves oddly: up to 10 volts, it shows erroneous values, but above that, it measures correctly. When changing registers, it measures correctly.
