Re: HP3400A common problem?


 

Hello to all members.

My 3400 developed a "stuck range switch" symptom.? At first it was a bit hard to turn and now it is completely jammed.? I cannot turn it even with pliers.? I tried IPA to dissolve the grease, a few drop of oil on front and rear sleeve.? All of this without any success.? Is it something that you experienced ?
