9790-03 contact needle is front-end test accessory exclusively designed for HIOKI L9790 thin connection cable, used together with Memory HiCorder series waveform recorders. Sharp slender needle tip enables stable contact measurement on PCB pads, small component pins and compact circuit gaps where alligator clips cannot reach. Equipped with insulating protective sleeves to avoid accidental short-circuit during multi-channel dense wiring test. Clear red/black polarity marking effectively prevents reverse connection errors during waveform acquisition on EV inverters and control boards.
