Hello Don,
Thanks. I was given an application note Rev B, April 2006. The R11 and R30 were replaced by 4.7 ohm and 33 ohm respectively.
I followed this note and replaced these two resistors instead of the values mentioned in KX1 Owner's Manual May 2010.
Is this matter the resistance check?

Johnny,
That is too low. Check the value of R24, R9, R27, R11 and R10. Check
carefully for any solder bridges.
You might also want to try new batteries in your DMM and try reversing
the leads on your DMM just in case its polarity is reversed from normal.
