This Fluke meter exhibits approximately 11 M ohm input impedance. The probes are passive (simply wires). This is a crude measurement, and so we are not concerned about impedance loading. All this is good for is making "qualitative" determinations of Fieldbus signal strength.
Very good ,thank you all in BTC inst. for such a great videos

When probing the Fielbus network ,how much impedence does fluck present on ?
Is It a active probe ?
