AEDATS III/IV AUTOMATIC DATA ACQUISITION TEST SYSTEM The AEDATS III test cell instrumentation and processing system is an innovative, rugged fourth generation system designed specifically to eliminate the environmental and supportability problems associated with general purpose commercial computer equipment. Utilization of AEDATS III with its new graphic user interface results in accurate and consistent engine tests and, with the incorporation of Referred Engine Diagnostic Data (REDD), the system assists the operator in evaluating the condition of individual engine modules. AEDATS III includes the following capabilities: Monitors, displays, and records engine and test cell data in real time Scales and converts inputs to engineering units Provides continuous background safety monitoring Alerts the operator when an unsafe condition occurs Prompts the operator through the test sequence Provides accurate and instant real time recording of data Maintains and prints standard and customized reports Performs engine diagnostics based on manufacturer's performance criteria The AEDATS III System consists of the Signal Conditioning Control Unit (SCCU), CRT Display, Keyboard, Printer, and Transducer Panel. The heart of the system is the innovative SCCU. This unique and compact unit contains the signal conditioning, processing, and memory storage for the system. The unit accepts and processes the input parameters present in the test cell. The main microprocessor is a Pentium® microprocessor which provides accelerated computation speed for data acquisition, correction, scaling, polynomial expansion in performance analysis, and data input/output. AEDATS is also available in the form of a Portable Data Acquisition System (PDAS). This system is perfect for test cell correlations because it is accurate, reliable, and portable.

AEDATS IV: Virtual Instrumentation
Howell Instruments offers an optional upgrade for AEDATS III that provides Virtual Instrumentation (VI), which replicates the function of analog instruments currently in the test cell. With VI, calibration errors related to antiquated instruments are a thing of the past.
With the optional AEDATS IV Virtual Instrumentation package, continuous and accurate monitoring of critical engine parameters is presented on a flexible display arm, enhancing safety by allowing the operator to position the display to ensure he is able to view the engine at all times. AEDATS IV provides for six "round dial" gauges and up to ten linear bargraphs, complete with limit indications and exceedance warnings. The design of the displayed gauges is based on the customer's needs.
