2 Testing Performance
3 Set up the oscilloscope.
a Set the Volts/Div setting to the value in the first line in Table 11 or Table 12
(depending on the oscilloscope model).
b Adjust the channel 1 position knob to place the baseline at 0.5 major division
from the bottom of the display.

A blocking capacitor is required at this range to reduce noise. See “Use a Blocking Capacitor to
Reduce Noise" on page 39.

Full scale is defined as 32 mV on the 2 mV/div range and the 1 mV/div range. Full scale on all other
ranges is defined as 8 divisions times the V/div setting.
