SHORT-OPEN TESTER FA1221

Multichannel short/open tester that can be embedded in existing test equipment

The FA1221 is a multichannel short/open 4-wire test equipment for populated board testing. Its small form factor lets you embed the unit into existing systems, which helps reduce installation time and costs.

Key Features

  • Functionality has been consolidated in a single, desktop tower that can be easily embedded in existing equipment
  • Specifically designed for short/open testing
  • Four-terminal low-resistance measurement for stable measurement of low resistance
