PRICING
Controller repairs are billed on a time and material basis.
Most controller repairs are accomplished under $500.00.
Major component failures (transformers, meters, etc.) may
increase cost.

TESTING
Instruments are fully tested and repaired to manufacturers specifications. All controllers are tested using a documented test procedure. Testing includes operation with appropriate sensors and output devices. Power output and I/O outputs are tested with test fixtures that we have designed and built for each controller. A completed test report and all defective parts replaced are returned with the repaired controller.
