Commercial System Testing

DataTest ERT 1000

This system is designed to meet the needs of commercial system manufacturers whose products require startup loads exceeding 100 Amps. Testing sequences are typically more comprehensive and have a duration of 10-20 min. This system specializes in multi-circuit and custom testing requirements. Testing sequence can be paused while adjustments and corrections are made.

Standard Features (in addition to those listed for the ERT 200 and 500)

• Performance testing compensation for ambient conditions
• Specialized high current tooling connections
• Multiple compressor and circuit testing
• Monitors indoor blower velocity and temperature
• Output can be configured to test Delta or Wye configurations
