I just bought an ADC-22 data logger a few days ago. I notice that when a voltage is applied to channel 1 (example 1.5 VDC) it will not only read 1.5 Volts on channel 1 but other adjacent channels such as channel 2-6 will read the same voltage as well, while channels far away such as 7-8 are unaffected. I tried grounding pins 23-24 but that did not work niether.
Is there a reason why there seems to be cross-talking between the channels or is my logger just not working properly?
Iam running the recorder software on windows XP, and I connect the logger through my parallel port.
Thanks in advance
