im measuring a noisy 12V capacitor using Keithly 2700 with keithly 7700 module:
when im measuring the cap voltage im getting wrong number (141V) while DMM measuring accurate ~12V.



i tryied diffrent channels,diffrent rates and still getting wrong measurment.
im logging using C# script if its matter.
anyone faced such issue?
is there any Keithly data logger software to dissaprove software issue?
thank in advance.
