SELECTING THE PROBE TYPE

To prevent measurement errors, ensure that your test tool
is adapted to your probe at power-on. Note that the
PM8918 probes, delivered with the test tool, have an
attenuation of 10:1.
For accurate measurement, periodic probe calibrations are
necessary. This is explained in Chapter 9, "User Mainte-
nance".
