D201-0501-CDT
D201-0501-CDT
Computerized Diode Tester

Features:
  • Heavy Duty, high accuracy, high speed (r to 6 second test), testing of automotive rectifiers and diodes.  PC based easy to use interface with rigid industrial design.  Available in models for sitting or standing operator.
  • Test standard and new generation rectifiers with up to 8 phases per alternator and up to 16 diodes per rectifier
  • Measures up to 16 resistance circuits
  • Completely programmable test conditions and test  limits including; avalanche voltage with current from 10 uA to 160A
  • Extreme accuracy and repeatability based on real time filtering and digital processing
  • Mechanical compression to simulate rectifier condition when installed into the alternator
  • Checks capacitors built into the rectifier
  • Quick tooling changeover time
  • Set limits and test diodes individually, verifies resistance from phase to phase at programmable points, compare diodes with max % difference.
  • Database with unlimited memory for test profiles, and (optional) supervisor statistical package
  • Programmable test profile includes; machine setup and operating instructions, diode group names for individual diodes and connections
  • Test connection verification before the test start to eliminate the possibility of false test results
  • Detects faulty soldered and terminal connections and verifies stator-rectifier connections before final alternator assembly
  • Interface with Pass & Fail indicators, reject bin valve to sort good and bad rectifiers, and Pass and Fail marking devices.
  • Measures Delta Vf (Rth) at up to 10 programmable test points with up to 120 Amps load
  • Scripting capabilities to control external devices or custom test sequence
  • High speed commutating circuit with solid state and high durability mechanical switches
  • will test rectifier with stator connected
  • Optional reverse leakage noise analysis for predicting rectifiers that will experience early failures
  • Optional learning mode with wizards to set up the test conditions, tooling, and limits
  • Detect diodes with "soft Knee" characteristics by testing reverse leakage at different voltage levels
  • User friendly graphical Interface with Optional LCD Touch Screen display identifiers the location of faulty diode
  • Label Printer Interface, Auxiliary digital I/O for external devices
    • Technical Data Measured Parameters:
    Break-over Voltage up to 500V, (optional 1000V)
    Breakdown test current up to 100 uA
