DATA ACCUMULATOR - TYPES OF DATA
CATEGORY...
Three categories of data can be entered into the Data Accumulator during a typical alignment
procedure. Some data is entered manually, determined by measurements observed or from a
specification book. Other data is entered through the Readout from the Electronic Gauge during the
actual alignment process. The three types of data are spec, before, and after. The type of data to be
entered is selected by pressing the appropriate BEFORE, SPEC, or AFTER key (Item 3, Page 7).
BEFORE This data is entered during the initial check of the vehicle.
