Attaching the attenuator with wrong polarity can damage the probe and the
external attenuator.
3. Press the probe gently into the attenuator until the micro button matches the
notch on the attenuator in a central position.
4. The oscilloscope cannot detect the external attenuator automatically. To
adjust the scaling for display, R&S ProbeMeter and offsets, select the attenua-
tor in the probe setup:
"Vertical" menu > "Probe Setup" > "Ch" tab > "Attenuator RT-ZA15"
When you use the probe together with the external attenuator, hold them at
the gripping section of the external attenuator to ensure optimal mechanical
stability.

The R&S

ZA15 external attenuator is already factory-adjusted. For usual
measurements, further adjustment is not necessary. For use cases with specific
requirements to common mode rejection, it is possible to adjust the external
attenuator when you use it together with a specific R&S

ZD10/20/30 probe.
Therefore, the external attenuator has 3 trimmers to adjust the common mode
rejection at DC and to adjust the pulse responses of the positive and negative
inputs.
