EN/IEC 61010-1 6.2.3 3.0mm Preset Controls Probe

The EN/IEC 61010-1 6.2.3 3.0mm Preset Controls Probe is a precision-engineered safety compliance instrument designed for accessibility testing of hazardous live parts through narrow-gap preset controls in accordance with international electrical safety standards. This specialized test tool targets equipment with fixed or semi-fixed preset controls—including household appliances (oven temperature selectors, washing machine program dials), industrial control panel switches, and medical device preset interfaces.

Featuring a 3.0mm diameter conductive stainless steel tip, the probe is engineered to penetrate the minimal clearances around preset control mechanisms to verify whether hazardous live components (internal wiring, terminal connections, energized parts) remain inaccessible during normal operation. The tool incorporates an insulated handle for operator safety and precise manipulation during testing procedures, applying a standardized 1N thrust force to simulate accidental contact scenarios.

This instrument is essential for manufacturers, testing laboratories, and quality control departments to demonstrate compliance with IEC 61010-1, UL 61010-1, GB/T 18216, and related electrical safety standards for equipment with preset controls. The probe facilitates systematic verification that preset control openings do not permit access to hazardous voltages, thereby mitigating electric shock risks in control-intensive devices.

NOTE: Model SMT-3001 is supplied without connecting cables. For testing with low-voltage test supplies (e.g., LISUN SMT-529CV), select model SMT-3001C with integrated cabling.

Technical Specifications:

• Tool Classification: 3.0mm Preset Controls Probe for hazardous part accessibility testing
• Key Dimensions:
  • Probe rod length: 100 mm
  • Probe rod diameter: 3.0 mm
  • Circular baffle diameter: 35 mm
  • Handle diameter: 10 mm
  • Handle length: 100 mm
• Primary Function: Detection of accessible hazardous live parts through narrow gaps surrounding preset controls; verification of equipment compliance with IEC 61010-1 and related safety standards
• Standardized Test Procedure:
  1. Conduct visual inspection of probe integrity (verify tip straightness, insulation condition) and confirm electrical conductivity using appropriate test instrumentation.
  2. Energize equipment under test (EUT) and configure preset controls to representative operating positions (e.g., oven temperature setting at 180°C).
  3. Grasp insulated handle and align 3.0mm conductive tip with the narrow clearance surrounding target preset control (dial periphery, switch housing interface).
  4. Insert probe into clearance with controlled 1N thrust force—terminate insertion upon encountering mechanical resistance from control mechanism or enclosure structure.
  5. Monitor connected detection instrumentation for electrical contact indications (signaling accessibility to hazardous live parts).
  6. Document test results: Compliance achieved if no electrical contact detected; non-compliance if hazardous parts are accessible through preset control openings.
