Re: Boosting LCD panel meter sensitivity
The easy way out, near the trimpot there's a resistor R2 ~ 27K -30k that
controls the ref voltage to100mv
for 200mV FS.
Half that resistor by placing another 27K in parralel, to give you 50mv ref
adjust the trimpot if needed.
the result will be 0 to100mv meter.
see ICL7106 data sheet for more info.
