DE5000 LCR meter displaying uH instead of mH
« on: January 25, 2019, 07:33:12 pm »
Having just purchased a DE5000, I performed the CAL and when measuring a .875 mH inductor, the meter is displaying 885 uH. Granted it needs to be unwound slightly but curious if that is normal or a setting I can change.

What is the question 0.875mH is exactly the same as 875uH?
I would say that 875uH is the preferred way to show the value.

Either way is fine, I wasn't aware that uF was the preferred way but was only curious if the meter has a mH display option if it should or should not be displaying it.

Anything between 1mH and 10m can either be displayed as 1000uH to 10000uH or as 1mH to 10mH, but above 10mH I would expect the meter to show mH.
With the SI prefix* you do not really expect values below 1, they use the next lower prefix, between 1 and 10 it is more or less optional (Depending on who you ask) if you use the lower prefix or the current prefix, above 10 you always use the current prefix.

*Why is it called prefix when it is after the number: It is because it is a addition to the unit, i.e. H has a prefix of m or u.
