The Chroma 16502 Milliohm Meter offers a wide 0.001mΩ to 1.9999MΩ measurement range. DC, Pulsed, and Dry-circuit test current driving modes enable the Chroma 16502 to be properly used in DC resistance measurements for various inductive components (coil, choke, and transformer winding etc.), cable, metallic contact (connector, relay switch etc.), and conductive materials.

  • Basic accuracy : 0.05%
  • Pulsed test current output mode is used to reduce thermal EMF effects on milliohm measurements
  • DC test current output mode is used to increase measurement speed for inductive DUTs
  • Dry-circuit test current output mode (limited Max. 20mV) is used to measure such contact resistances where the maximum open-circuit voltage must be limited to 50mV
  • Temperature correction (TC function) regardless of material or temperature
  • Useful temperature conversion function for motor/coil evaluation
  • 4 channels R scan with balance check function for fan motor (combined with A165017 option)
  • wide 0.001mΩ~1.9999MΩ measurement range with 4½ digit resolution
  • Standard RS-232 interface
  • Optional GPIB & Handler interface
  • Bin-sorting function
  • Comparator and pass/fail alarm
  • Large LCD (240 x 64 dot-matrix)
  • Friendly user interface
