Vertical Scale on Oscilloscope
The actual vertical scale of the oscilloscope is equal to the attenuation
factor (10x) multiplied by the range of vertical scale selected on the
oscilloscope. For example, with the oscilloscope on 2.0 V/div, the
real vertical scale is 10 x 2.0 = 20 V/div. This value applies when the
oscilloscope is set to a 50 Ω input impedance input. If the oscilloscope
is set to the typical 1 MΩ, the actual vertical scale will be cut in half to
10 V/div. See Table 1.

4 Cleaning
This probe does not require any particular cleaning. If necessary, clean
the case with a cloth slightly moistened with soapy water. Make sure
the probe is completely dry before reconnecting it to an oscilloscope.
WARNING
Dry the probe thoroughly before attempting to make voltage
measurements.
CAUTION
Do not subject the probe to solvents or solvent fumes as these can
cause deterioration of the probe body and cables.
