Coarse Resolution
Fine Resolution
1, 2,5 sequence.
Depends on Deflection Factor, as follows:
Rotating the Fine control one increment
will change the Deflection Factor by 1% of
the next more-sensitive Coarse setting.
For example, with deflection factor set to
198 mV, rotating the Fine control
counterclockwise will cause this sequence
of sensitivities: 199 mV, 200 mV, 202 mV,
etc. Rotating the Fine control clockwise
from 204 mV/div will cause the reverse
sequence (202 mV, 200 mV, 199 mV, etc.).

Accuracy
See Deflection Factor Accuracy, which
precedes this characteristic.
Range, Resolution depend on
Deflection Factor, as follows:
Between 1 mV and 99.5 mV/div.
±1 V. Coarse and fine resolution are 0.25 div.
(250 pV) and 0.025 div. (25 jiV), respectively.
Between 0.1 V and 0.995 V/div.
±10 V. Coarse and fine resolution are 0.25 div.
(2.5 mV) and 0.025 div. (250 pV, respectively.
Between 1 V and 10.0 V/div.
±100 V. Coarse and fine resolution are 0.25 div
(25 mV) and 0.025 div. (2.5 mV), respectively.
