The Measure lead TP-C812B is a low noise differential measure lead designed to be used with the Handyscope HS4 DIFF and Automotive scope ATS5004D. This 2 meter long measure lead splits in two individual ends of each 1.2 meter long. The BNC connector at one end plugs directly on the instrument. The two other ends each feature a single 4 mm banana jack, on which application specific test points, clamps or probes can be plugged.
The Measure lead TP-C812B is very flexible, uses a heat resistant silicone isolation and shrouded banana jacks.

The input of the Handyscope HS4 DIFF or Automotive scope ATS5004D is differential, which means that both sides of the input have a high impedance. There is no connection to ground as in conventional oscilloscopes which are used with coax cables. Using a coax cable on the Handyscope HS4 DIFF or Automotive scope ATS5004D would result in the Handyscope HS4 DIFF or Automotive scope ATS5004D picking up a lot of external interference.
The specially designed Measure lead TP-C812B has a high Common Mode Rejection Ratio (CMRR), it is very insensitive to external interfering signals. The two ends can be placed up to more than two meters apart, while picking up very little interference. With a conventional oscilloscope with a standard oscilloscope probe this is not possible. The maximum distance between the positive side and ground is then usually limited to approximately 20 cm. And this 20 cm is very susceptible to interference. The Measure lead TP-C812B for the Handyscope HS4 and Automotive scope ATS5004D does not have this disadvantage. External interference is very well suppressed by the special construction of the Measure lead TP-C812B. Measuring between two distant points is now possible.
