I is not meant to confuse anyone, but must take into consideration all possible variables.
If one were to look at the schematic and understand which components are installed and which are not at the point when you make those measurements, you will understand why the readings are so high - many of the early checks are for signal paths that go off the board and they are connected to nothing - so you should read an 'infinite' resistance - the real reason for the check is to be certain there is nothing shorted. So why does the manual indicate '>100k' when the actual expected resistance should be infinite? you may want to ask. I don't know for certain, but I would not put out a kit that would be tested with a large variety of DMMs and state it any other way - there is no way that the manual writer can predict how your particular DMM will respond to an open circuit, plus, if one gets a part of his body in contact with the path being measured, the DMM will likely indicate some actual resistance, I have one that reads abotu 400K across my finger, and I have another that reads about 3 megohms - of course that depends on how much moisture I have on my skin too. So ther is no way to communicate properly for all meters and measurement situations other than to state that a reading above 100k is just fine. 73, Don W3FPR > -----Original Message----- > > I've always been confused by this kind of direction. > For example: > > 101k is also greater than 100K, but what's better: > 101k or infinity?
