I think mine is way overdue for a recap,
or whatever is causing the needle to not lock on to the far left zero position, and drift forward instead = useless
This is/was/might be again? my best TRUE RMS meter
My personal whining aside
assuming your unit was fairly calibrated to begin with,
and replaced the capacitors with 'exact enough' caps,
does it need calibrating?
i.e. have you also checked it against a second standard or decent TRMS multimeter that kicks to at least 100khz AC ?
