DataView (CD294) Dual Line Data Display 1. Introduction The DataView is a two-line, 32-character LCD that displays a real time input location value along with a pre-defined description string and units string. Two buttons allow the user to scroll through the programmed locations that are updated as often as they are measured. When the user has not pressed a button in the last two minutes the DataView switches to low power mode, drawing a current of less than 100 μA.
