TA467 Insulation Tester User’s Guide 1. Description The TA467 Insulation tester is specially designed for vehicles with on-board high voltagesand conforms to EN61010 CAT III (1000 volts) and CAT IV (600 volts). The insulation test function allows testing of the insulation of the high voltage wires found on high-voltage vehicles. It can be used as a stand-alone device or linked wirelessly with a USB interface to a PC or laptop so you can have the results graphed, saved or printed. -
