Model 2226A Digital Micro Ohmmeter - Overview
 

Overview
The digital micro ohmmeter type 2226A is a unique instrument capable of handling even the toughest resistance measuring applications. The type 2226A is designed to measure resistance values in the range of 0.1Ω to 20kΩ.

 

Model 2226A Digital Micro Ohmmeter

 

Features

  • Four-wire Kelvin principal eliminates unwanted resistance.
  • .Selectable test currents up to 10 Amps.
  • Used for quick and accurate low-resistance measurements.
  • Charging inductor mode for reduced settling times.
  • Wide resistance measuring range of 0.1Ω to 20kΩ.
  • 4-1/2- digit high contrast LCD display.
  • Safe operation - use of status indicators.
  • Available data output and remote programming capability via USB interface.
  • Automatic temperature compensation for copper and aluminum.
