HDR graticule vertical scale setting. When an HDR graticule is selected for the
Waveform display, you can use the Left / Right arrow keys to toggle the vertical
scale units between NITS, STOPS, or REFLECTANCE. Camera operators can
use the graticule lines at 2%, 18% or 90% Reflectance to properly setup camera
exposure with a camera test chart of 2% black, 18% gray and 90% white.
Gain adjustment. When the ST2084(1K) or ST2084(10K) HDR graticules are
selected, a fixed zoom mode from 100 Nits to maximum scale is available by
using the Up arrow key to enable Zoom Mode and the Down arrow key to disable
Zoom Mode. When Zoom Mode is enabled, the Gain function and the Vertical
Position controls are locked in a fixed configuration. When in HDR modes,
Variable Gain will be enabled by default to facilitate the Zoom mode function.
Voltage cursors. When HDR or HDR Full mode is selected as the Dynamic
Range setting, the mV voltage measurement cursors are replaced by a set of Nits
measurement cursors.
