Use of the 10:1 Probes
Distribution of stray capacitance:
Considering the stray capacitances, make sure to correctly connect the
reference conductors for each probe. The conductors should preferably be
connected to the cold points to avoid the transmission of noise by the stray
capacitance between modes.
The noise of the digital ground (earth) is sent to the analog input by stray
capacitance.
NOTE: To prevent electric shocks or possible fires, never use
accessories on which the casing is accessible if it has a voltage of
>30 V
RMS
10:1 Probe Calibration
For the best response, you must adjust the probe's low-frequency
compensation.
NOTE: To carry out this adjustment, the two channels of your
oscilloscope must be disconnected from the measured circuits before
opening the battery housing cover.
