The readout actuator pin prompts the automatic switching of the alphanumeric V/cm waveform scaling information on oscilloscopes with an on-screen display, or illuminates a x10 indicator on earlier RA capable oscilloscopes.

This high impedance oscilloscope probe is designed and calibrated for use on instruments with an input impedance of 1 MOhm shunted by 15 pF.

However, the TEX500RA can be low-frequency adjusted to work with instruments having an input capacitance anywhere between 10 to 35 pF.

Users can further fine-tune the probe by using the three incorporated high-frequency trimming adjustments within the adjustment box near the standard BNC connection.

Accessories include: a hook-tip adapter, a ground-lead clip, a probe compensation adjustment tool, an IC ground sprung adapter, a BNC to probe tip adapter, a spare probe tip, two probe tip caps, and two probe identifier clips, all neatly packaged with the TEX500RA probe in a clear pouch.
