[Elecraft] T1 Tuner Kit Control Board final check issues

[Erik Tkal]

Hi Don,

Yeah, I don’t often perform measurements on components already installed in a circuit, so the behaviour was confusing.  I thought I bought a nice DMM but I guess it was just a fluke… ;-)

Anyway, I got it finished and everything is operational, now just have to wait for the IC-705 interface cable!

  Thanks and 73,

Erik,

Yes, using auto ranging on the DMM can cause false readings.  Try to set the fixed range a bit above the highest expected resistance for the best results.  It all depends on the voltage the DMM applies to the circuit.  Too high a voltage can make ICs and transistors conduct causing a low reading.
