Built in-house

  • Circuit design — we design the measurement circuits ourselves.
  • Control software — we develop the measurement routines and the user interface. Entering the conditions, plotting the graph and saving the data all happen in one program.
  • In-situ zeroing — beyond the factory calibration, the current zero can be re-taken in the actual measurement setup.
