TH2830 vs TH2832
KungFuJosh:
In case anybody is curious, you can correct for cable length on these meters. Not yet?
Martin72:
Try switching to 1m or more....does ist work? On our ST2830 not(It is even described in the manual that it won´t work), but we didn´t have the latest firmware.
KungFuJosh:
Oh, that's both annoying and interesting. It says "no cable data installed." Maybe time to email ST and ask them if they know anything about it.
Martin72:
Yes, I noticed this when I connected the fixture from Aliexpress to our ST2830 last week and saw 0m on the display.
But we always use the Kelvinclips, so I tried to switch it after the tests and it didn't work.
mawyatt:
Our TH2830 doesn't allow cable compensation either. This likely entails some calibration parameters and setup with test fixtures, there is also the issue with cable propagation constants which may not be the same for all cables.
If we did the math properly, at 100KHz a 1M cable with Propagation constant of 0.66 has a phase delay of 0.1818 degrees.
Best,
