Ranging issues
Closed this issue · 6 comments
When having heavy step loads during ranging (particularly if near range edge), it takes meter few samples for meter to switch ranges (while in autorange).
Recommendation:
Use max range for ranging, accuracy is good enough (about 40mA in 20A range, per yokogawa calculator) to be able to make correct decision about wat is appropriate range to be used for measurement.
Alternative solution is to update checker to ignore ERROR: Current appears to be too high for set range and ERROR: Bad watts reading inf from WT330 during ranging phase
Just to bump here, my WT210 is having this issue now during almost every run when ranging. It is making it difficult to get passing logs.
not too surprising since wt210 as lower internal sampling rate, so it will take more time for to come to its senses in autorange mode.
are your run logs clean of errors?
Yep --
run1/spl.txt has good values/no errors for every poll
ranging/spl.txt has the occasional few lines of:

Whitelist:

Grabbed the wrong error, here are the correct one that relates to Po-Hans whitelist above:
