  • ST Series - Starter Testers: ST-20Fully automated precise testing for high volume applications at the touch of a button
  • Load test units up to 50 Nm (optional 75 Nm) with improved accuracy
  • Equipped with free-run speed sensor to verify starter rotational speed
  • Available optional Solenoid Block Test for through diagnosis
  • Reject bin input, marking device output, very fast change over time, automatic clamping, connections, learning mode to create new test profiles, real time statistical monitoring, safety level IV protection, programmable installation and setup instructions, and serial number support
  • Measures more than 40 different starter parameters including; performance curve with load, free spin current and speed, solenoid current, contact voltage drop, and "R" terminal function
  • User configurable Labels, Pass and Fail reports with performance curve plotting torque, power, speed, and voltage
  • Computer controlled programmable 1600 Amp starter power, simulating 200 - 2000 CCA battery (0 - 30 milliOhms
  • Computer controlled 150 Amp programmable solenoid power supply, solenoid pull-in can be tested at a programmable reduced voltage during the test to insure operation under worst case conditions
  • Load test conditions can include speed, torque, current, power and voltage
  • Tests starter, solenoid, drive, and spring engage and disengage timing, this can reveal faulty components or assembly errors
  • Built-in oscilloscope, precise waveform analysis which can detect armature, commutator and brush problems
  • Programmable solenoid "aging" function to seat the solenoid contact
  • Can scan a full performance curve in 12 seconds which increases the accuracy by decreasing test result variation caused by temperature change
  • Supplied with flat touch screen color LCD monitor
  • Available in many working voltages (220 to 480V at 50/60 Hz)
  • Engine firing simulation
  • Built in endurance test capabilities
  • Test data logging with graphical display of test cycle for analysis
  • Equipped with light curtains for added safety protection
