The Measure lead TP-C812A is a low noise differential measure lead designed to be used with the
Handyprobe HP3.
This 2 meter long measure lead splits in two individual ends of each 1.2 meter long.
The special dual banana jack at one end plugs directly in the Handyprobe HP3.
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 input of the Handyprobe HP3 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 Handyprobe HP3 would result in the Handyprobe HP3 picking up a lot of
external interference.
The specially designed Measure lead TP-C812A 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 probe this is not possible.
The maximum distance between the positive side and ground of a standard probe is usually limited to
approximately 20 cm.
The Measure lead TP-C812A for the Handyprobe HP3 does not have this disadvantage.
And external interference is very well suppressed by the special construction of the Measure lead TP-C812A
Measuring between two distant points is now possible.
The Measure lead TP-C812A is very flexible, uses a heat resistant silicone isolation and shrouded banana jacks.
