Measure lead TP-C812C

Measure lead TP-C812C

The Measure lead TP-C812C is a low noise differential measure lead designed to be used with the Handyscope TP450. This 2 meter long measure lead splits in two individual ends of each 1.2 meter long. The dual banana socket connector at one end plugs directly on the european mains plug adapter that can be attached to the instrument. The two other ends each feature a single 4 mm banana plug, on which application specific test points, clamps or probes can be plugged.

The Measure lead TP-C812C is very flexible, uses a heat resistant silicone isolation and shrouded banana plugs.

The input of the Handyscope TP450 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 this instrument would result in the instrument picking up a lot of external interference.


The specially designed Measure lead TP-C812C 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-C812C for the Handyscope TP450 does not have this disadvantage. External interference is very well suppressed by the special construction of the Measure lead TP-C812C. Measuring between two distant points is now possible.
