[Elecraft] Initial test - resistance check in KPA100 contradicting measurement results

[Rolf Schröder]

Hi,
while measuring the resistances according to page 20 of the KPA 100 manual, I 
found the following:
while measuring in th 20k range, all resistances that should have been >10k 
were around 8.3k: U1 pin 2, 3, 13, 14, 27, 28, or U4 pins 1 and 8(too low)
When measuring in the 200k range all resistances were in the 35k range, 
measuring in the 2M range produced measurements of about 250k or, to be more 
specific:
DVM range:  20k    2M      20M
U1 pin1         3,7k  3,9k     3,8k
U1 pin2         8k     34k      255k
U1 pin3         8,3k  34,7k    260k
More values upon request but pattern is the same for the rest of the pins of 
the ICs. Measuring between banded end of D10 and ground as well as measuring 
between AF pad and gound showed infinite resistance. I am using a Metex 
M4640A DVM and have replaced the battery of the DVM just ten minutes ago. 
(thought it might have been a weak battery. Any ideas?
