Check the listing for details. Sheffield TA500 Multisystem Engine Analyzer NEW. Condition: New. Listed at 227.73 USD. The TA500's unique and proprietary technology allows the user to perform quick and reliable diagnostics of non-starts, misfires, fouled up or damaged spark plugs and/or spark plug wires, by comparing digital read-outs of the spark plug voltage and spark burn time between cylinders on engines using Coil on Plug, Coil near Plug, conventional distributor/ignition coil, DIS (Distributor-less) or waste spark and magneto technologies.Simple to use, the TA500 requires no special adapters, cables or a scope and is equipped with a large digital display that shows spark plug voltage, spark burn time, RPM, as well as Min/Max readings in real time.Multisystem ignition analyzerMeasures spark plug voltage from 0 to 50000 VoltMeasures spark burn time from 0 to 10 msSpecial antenna sensor allows quick testing of Coil on Plug and Coil near Plug modules, and easy hook-up to spark plug and ignition coil wiresNo ground wire connections required, for fast troubleshootingMultiple diagnostic applications are described in comprehensive User's Handbook (Included)Tachometer functionFor 1 to 12 cylinders and 2, 4 cycles with special DIS (Distributor-less or waste spark) mode.Measures from 200 to 20000 RPM on a 4-1/2 digits LCD displayAdvanced microcontroller technology yields 0.5 % accuracyWorks on Coil on plug, Coil near Plug, DIS (Distributorless or waste spark), Conventional, Magneto and other spark ignition system.
