My Hantek 1833C handheld LCR will go through the open and shorted lead calibration process fine, and zero out with it. But nothing I seem to do will allow it to retain the calibration into memory when it's powered off, it always powers back on showing 7-8 pF. The open lead calibration takes several minutes, which is annoying. I did update to the latest firmware, but no fix. Has anyone else figured this bug out on these?
Thanks, Mark KC3PKK
