Hi guys, I'm very happy with this old guy, but wonder is it possible to "extend" the measuring frequency range in external oscillator mode. It works above 10khz (manual say 50hz-10khz) but not precise as in the described range. Can someone figure out what part of this machine limits it's measuring range.? Maybe it's possible to "open" the range?
