What is the input impedance of the DI-8B41-09 Module?

I would like to know the input impedance of the DI-8B41-09 Module. I don't want to load down my measurement by using the DI-8B41-09 if the input impedance isn't high enough.

The datasheet http://www.dataq.com/resources/pdfs/datasheets/di8b40_41.pdf specifies 500kΩ (minimum).

Ken,

So if you are specifying the 500kOhm minimum then that is the figure I need to use so if I need a impedance similar to a multimeter (10MOhm) I shouldn't use the Dataq DI8B41-09. Thanks for the information.
