Adjustments
The P6209 has two internal controls: offset zero and offset scale.
These controls rarely need to be adjusted and only should be changed
after a probe performance verification and functional check has been
performed on the oscilloscope.
To make adjustments to the probe, the compensation box bottom
cover must be removed and the equipment allowed to warm up for
20 minutes. Use the optional adjustment tool for making any
adjustments. Refer to Table 5 on page 33 for a list of the equipment
required to adjust your probe.

Using a Pozidrive screwdriver, remove the four screws that attach
the bottom cover to the compensation box. Gently remove the
cover. Refer to Figure 16.
