1833C ESR table

Many of the devices that measure ESR have a table of approximate values, which table should I use for the 1833C?

We can not understand you cleally. Please give us more information to study. Thanks.

I was referred to a reference table, the approximate values ??that I should measure

You have to check the datasheet of the specific capacitor to know what value you should measure.

Generic ESR charts for electrolytic caps are basic useless. If you feel better looking at one, just google it and choose anyone that you like.

Why is the 1832 meter showing negative ESR on some capacitors?

I have a 1833 device, and not the one on your video, and it shows a negative ESR when measured with a 600mV signal, when measured with a 300mV signal, the readings are positive. The capacitor and frequency are the same.

Please update attached latest firmware. Then do open (OPEN) and short (SHORT) circuit correction.

Thanks for the update, but the problem remains, on film capacitors when measured at 600mV, it shows negative ESR, when measuring the same capacitor at 300mV, the result is correct.
