Abstract
Abstract An engine analyzing system includes an engine analyzer unit having a CRT display screen for displaying display data based on parameter data received from an associated engine. The system also includes a remote portable display unit with a second CRT display screen and a display control keypad. Each of the analyzer unit and the remote display unit has a wireless transmitter and a wireless receiver. The data displayed on the analyzer display screen is transmitted to the remote unit for display on its screen. By use of the keypad display control signals are transmitted from the remote unit to the analyzer unit for controlling the analyzer unit display and, thereby, the remote unit display.
