Programming guide
The SQ series of handsfree probes from Sensepeek have a lower point of gravity making them even more stable compared with the original SP series of handsfree probes. All probes in the SQ series are also insulated and can be used handheld as any traditional probe but their full potential is used when measuring handsfree.
The SQ series of oscilloscope probes also includes more ground options, have probe tip protection, longer cable and support for oscilloscopes with automatic scaling (10:1).
All the loved features of handsfree measurement, exchangeable fine pitch spring tipped test needle, color-coded cable holders and the minimalistic design is maintained to make traditional sized and handheld probes obsolete.
Both length and weight of the SQ probes are perfectly balanced to be used with PCBite PCB holders and base plate which is a must for handsfree function.
