Abstract
A testing apparatus includes a holster including a jack defining a conductive periphery configured to connect with a reference lead of the voltage probe to form a common ground. The apparatus includes a shunt defining first and second regions of different potential having predetermined difference. The second region is configured to connect with a reference lead of the shunt probe. The apparatus includes a bridge configured to connect the shunt probe lead with the common ground.
Claims20
A testing apparatus comprising:
- a holster including a jack defining a conductive periphery connected with conductive wires configured to connect with a reference lead of a voltage probe to form a common ground;
- a shunt defining first and second regions of different potential having predetermined difference, the second region configured to connect with a reference lead of a shunt probe;
- and
- a bridge configured to connect the reference lead of the shunt probe with the conductive wires of the common ground.
A testing apparatus comprising:
- a shunt defining first and second regions of different potential having predetermined difference, the second region configured to connect with a shunt probe lead;
- and
- a holster including a jack having a conductive periphery sized to interconnect with a ground lead of a voltage probe forming a common ground with the holster, and a shield disposed partially between at least one of the first or second regions and an active lead of the voltage probe.
A testing apparatus comprising:
- a holster including a jack defining a conductive periphery connected with conductive wires configured to connect with a reference lead of a voltage probe to form a common ground;
- a shunt defining first and second regions of different potential having predetermined difference, the second region configured to connect with a shunt probe lead;
- and
- a bridge, traversing a shortest distance between the shunt probe lead and the conductive wires of the common ground, configured to connect the shunt probe lead with the common ground such that the common ground includes the second region and the holster.
