Description
This is a brand-new lead and offers dynamic measurement of resistance which is a feature Pico are using within their guided tests.
The TA432 offers a diode test function in addition to resistance measurements.
This accessory is only available for PicoBNC+ and will not work with older PicoScope models.
The TA432 has a total lead length of 2m in a Y configuration, with the non-PicoBNC+ ends being 1m in length and terminated in a 4mm non-shrouded connection.
The lead contains an active current source and is intended to be used only on unpowered components and wires.
Frequently Asked Questions
Why measure resistance with an oscilloscope?
The PicoBNC+ resistance lead lets you measure component resistance directly through your PicoScope, displaying resistance changes over time as a waveform rather than a single number. This is valuable for detecting intermittent high-resistance connections, throttle position sensor wear patterns, and temperature sender characteristics.
How does it differ from a multimeter resistance reading?
A multimeter gives a single static value. The PicoScope with resistance lead shows how resistance changes over time or through a range of movement, revealing intermittent faults and wear that a spot measurement would miss. PicoBNC+ provides automatic scaling via PicoScope 7 software.
