MODEL M300RT

Insulation Resistance Test Instrument

Safe, Fast, Efficient

• Performs DC insulation resistance test – detects up to 4000 megaohms at 500 VDC
• Test in compliance with UL, VDE, IDE, and MIL STD 202 test standards

Production/Quality Assurance Testing

• Fully automatic test cycle
• Detects and indicates the following:
  • Test Ready (security chassis ground sensed)
  • Test in Progress
  • Test Passed
  • Test Failed
• Following test parameters easily preset via rear:
  • Voltage ramp
  • Test time
  • Insulation resistance trip point
• Switch-selectable ramp and test time combinations
• Arc detection circuit
• Solid state control circuitry for 2 millisecond shut down

Superior Safety Features

Continuos Ground Continuity Monitoring

• Shutdown within 2 milliseconds after insulation breakdown, or low insulation resistance
• Electronically controlled output voltage ramp rate circuit guarantees consistently smooth ramp
• Visual (audible optional) indication of high voltage applied to DUT
• Visual and audible indication of insulation breakdown or low insulation resistance
