Superior Signal Conditioning
A 4000 instrument's internal scan cycle typically produces 1000 finished engineering-unit answers per second (this includes linearization, "y = mx + b" scaling, limit comparison, cross-channel calculations, and other numeric processes). 16-bit A/D resolution with multipole per-channel analog filtering and selectable per-channel digital filtering yields rock-solid stability and a typical overall accuracy of 0.02%, following calibration by the user (see Specifications).
A number of calibration techniques are available, including "absolute," "actual" or "simulated" two-point ("deadweight"), and "calculated." The best calibration method to employ will depend both on the conditioner model and on known characteristics of the measured test or process.
A nonlinear input (such as that produced by an LVDT or Eddy-current proximity sensor) can be calibrated by using one of the instrument's eight internal "look-up" tables. By entering a zero point and up to 15 subsequent linearization points, you can easily define the ideal linear output for the channel in question.
For batch weighing and other applications that require auto-taring, and appropriate offset value can be automatically applied at the touch of a button, by external command.
