ACJr pH/temp reading problem

When I have the pH probe unplugged, the temp reading is 2 degree lower, which correlate with my big digital temp display. When the pH probe is plugged in, the temp is 2 degrees higher. Any idea why that is?

This seems quite strange, and I have not heard of a similar problem. Is it correlated with a device being on/off? If you simply plug the pH probe in and it is not in contact with the water, does the temperature reading still change?

I will try that when I get home and let you know.
