How to Implement the Probe Compensation
When connect the probe with any input channel for the first time, make this
adjustment to match the probe with the input channel. The probe which is not
compensated or presents a compensation deviation will result in the
measuring error or mistake. For adjusting the probe compensation, please
carry out the following steps:
1. Set the attenuation coefficient of the probe in the menu as 10X and that of
the switch in the probe as 10X (see "
How to Set the Probe Attenuation Coefficient" on P101), and connect the
probe with the CH1 channel. If a probe hook tip is used, ensure that it
keeps in close touch with the probe. Connect the probe tip with the signal
connector of the probe compensator and connect the reference wire clamp
with the ground wire connector of the probe connector, and then press the
button "Autoset".
2. Check the displayed waveforms and regulate the probe till a correct
compensation is achieved (see Bild 0-6 and Bild 0-7).
