the thing is theoretically capable of more precise function that it's claimed but in practice . . . i don't think it can do even twice the claimed 4%
. . . there are 3 to 6 constants that have to be set correct at the 10-th of a % precision -- but they are valid at a specific device working temperature + don't with-count / cancel-out the variation of parasitic properties of different capacitors
experiment ::
the diodes have a logarithmic voltage --or-- apx. Δi.D ~ exp(U.D) ... also the ΔU.c ~ exp(t) ...
... thus Δi.D ~ exp(exp(t)) --or-- if the U.c rises the frequency (Δi.D) must rise exponentially to provide ?? more linear U.c scale → the meter should run at constant outp voltage and varing frequency (4 starting ...)
