The ST-24 is designed to provide fast, accurate, and detailed test results of starters.

This machine checks the starter by simulating real working conditions of the vehicle. For an accurate starter test the ST-24 detects solenoid, drive and spring problems by analyzing device timing. During the test, the ST-24 automatically recognizes the starter rotation direction and applies a programmable load. The mechanical energy produced from the starter is returned back to the power supply to reduce power consumption. The performance curve is scanned in at a set of programmable points.

The ST-24 can scan a full performance curve on the starter in less than 10 seconds which increases the accuracy and decreases result variation caused by temperature. The ST-24 has built in separate power supplies for the starter and for the solenoid. This way the solenoid functions can be tested at a programmable reduced voltage during the test. Solenoid voltage drop is monitored during the “all test” procedure to ensure the contact system is working reliably. This testing system provides a precise waveform analysis for accurate armature and commutator diagnostics. The output ripple can be monitored on the built in oscilloscope with automatic adjustments.When the test is complete, the results are evaluated against preset limits and a programmable output report is generated. The set of starter performance curves is displayed on the screen. The machine can control up to two printers generating different programmable reports with performance curves and scope patterns. Bar codes and serial numbers can also be automatically generated.
