Service test generator STG-02
The service test generator STG-02 is used to test, service, and calibrate SPM's
instruments for shock pulse and vibration measurement:
• Machine Condition Testers (T)
• Machine Condition Analyzers (A)
• MG4 System
• CMM System, shock pulse and vibration measuring units
• CMS System, measuring unit BMS
• Measuring unit VCM-20
• Vibrameter VIB-10A/11A and VIB-20A
To test the instrument, the STG-02 simulates the following transducer signals:
• Shock pulse transducers type SPM 40000 and 42000
• SPM vibration transducers TRV-01, TRV-12, TRV-18, TRV-20, TRV-22
• Customer defined vibration transducers with voltage and charge output.
The STG-02 has the casing and the display of the A30/T30 and is operated via its
key pad. The test programs are menu selected.
For shock pulses, there are three different testing modes: single pulse, STG pulse
and TLT test. STG mode generates the same signal as the test generator STG-01
Vibration can be tested in single frequency or mixed frequency mode.
The STG-02 should be calibrated once per year at the SPM facilities in Strängnäs,
Sweden.
