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 8, "User Mainte-
nance".
WARNING
To prevent electric shock and personal injury, Mini Test
Hooks and HF Adapters must not be connected to any
voltage higher than 42V peak (30V rms) to earth.
