Question:


I bought one LRC meter type 1833C from Banggood.

I have some problem:

I cannot measure some high quality capacitor with 10 ....15 uF just up to 10khz.
It not measured at 40kHz or more,
I did open and short calibration, the lower capacitance is ok up to 100kHz but more than 10uF not.
The user manual showing:

Maybe because the capacitor type you are trying to measure is not a capacitor anymore at that frequencies...

Check the capacitor's datasheet to see which test conditions the manufacturer recommends.

It's easy to check. I took 2 capacitors of 6.8uF, measured them at all frequencies separately. Everything was measured correctly. Then I connected it in parallel and measured it again. From a parallel connection, these capacitors did not cease to be capacitors, but in 1833 the device does not show capacitance, although it shows secondary parameters ESR and others at frequencies above 10 kHz.

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