[Elecraft] Problem with Current Meter

2007-06-20 Thread Eduardo Jacob

Hi again

More specifically, what we have done is:

Change the Q11 transistor with a new working one (checked )
Remove U3, put a socle and try with a new one.

[Elecraft] Problem with Current Meter

2007-06-19 Thread Eduardo Jacob

Hi

A friend of mine is having problems with the current detector. When he
presses the display button the voltage is displayed but the current shows 0.
We have been tracing the circuit which is fairly straight and we are not
able to get the solution. We have changed the LM833 and the PNA
transistor. We have checked the current sense resistor and it seems it's
working. Does any body found before this problem?

Regards

 I can heartily endorse the AADE LC meter  ( see http://www.aade.com/)
 
 I received a kit for Christmas, built it in less than 2 hours, and have been
 extremely happy with the unit.  The AADE unit won't do large value polarized
 caps, but generally the application of such caps (bulk capacitance for 
 filtering)
 is generally one where  precision measurement is not important .
 
 The accuracy and resolution of low L and C ranges with the AADE unit
 is just what I needed at my bench.
 
 Consider this a four thumbs up for the AADE unit. Good folks and good 
 product
 for a fair price.
