NON·CONTROLLABLE FUNCTIONS
Since control and monitor functions of the inter-
face are implemented to obtain remote measure-
ment capability, certain front panel controls are
not implemented in the interface due to their
local operator orientation. A list of these oper-
ator oriented controls are as follows:
Power On/Off
Power Mode Indicators
Display Focus
Display Intensity
