hi, no heat from hakko 808. the heater reads 45 ohms. it seems the leads connecting htr to rest of circuit became unwelded. can anyone sugggest how to re-attach the leads. this would make the 808 functional again.
hi all, well i finished construction and programmed the hex code into the micro. this meter measures esr and capacitance at the same time in circuit. just need to calibrate.
thank you for your response. unfortunately, i do not have access to a accurate lcr meter. even more unfortunate, i have no idea what a transfer standard is.
i know the tolerance is large (20%) in modern electros. there are occasions when the esr is good, but the capacitance value is much lower than it should be. these are the caps that are missed when relying on esr only. its 470mfd.
