I'm using a Digimess HUC3100 LCR meter to measure both the capacitor and the resistors,all component are ordered from RS components,which I believe it should be in its stated tolerance ,even if the meter is with a accuracy of +_ 10%,the time constant should not be of by 6 second,anout 400% off,and the PCB I'm using I tried both capacitor,the electrolytic Capacitor and the ceramic capacitor,all other component remains the same,only variable is the capacitor itself
The measured capacitance of both capacitor are as follow
Electrolytic Capacitor - 10.6uF
Ceramic Capacitor - 9.8 uF
with the same meter
can there be a possibility that a non polarized capacitor cause the error?
