The Fluke TP88 rigid back probe pins are better than a test probe alone. These two-inch long, rigid back probe pins easily pass between the weather pack seal and wire. A sharp point on the Fluke TP88 pins ensure good contact to the electrical connector and the pin’s insulation protects it from shorting to other wires.
The Fluke TP88 rigid back probe pins slide onto test probes measuring 2 mm (0.08 in) and are tested to 60V DC.
