Abstract
The present invention relates to an apparatus (202) as well as a method for monitoring mobile grounding devices (102), wherein the apparatus (202) comprises the following: a first pole (204) for connecting to a mobile grounding device (102); a second pole (206) for connecting a reference probe (208); and a control device. The control device is configured so as to sense an electrical resistance between the first pole and the second pole (204, 206) and compare it with a threshold. The control device outputs a status signal based on the comparison between the electrical resistance and the threshold.
