text: RESPONSE & DISPLAY RATES
  Delcom meters sample material every 30 ms. Delcom firmware and software perform pipeline averaging and display 8 averaged readings every 240 ms.
  Delcom meters are calibrated to better than 99.9% accuracy against National Institute of Standards and Technology (NIST) standards. User can calibrate a meter with one standard in one minute.
  Significant digits available at each order of magnitude for each of the four meter ranges.
  Delcom guarantees no more than 3% deviation from the true sheet resistance value of tested material. The chart below shows a Delcom meter tested against 10 NIST, VLSI, and MSA standards.
  Delcom meter readings are effectively 99.9% repeatable if sample placement and environmental factors, such as temperature, are held constant.
  The baseline readings of eddy current instruments drift with changes in ambient temperature. Delcom benchtop sensors are compensated so they drift no more than .04% of total resolution per degree Celsius per hour.
  EFFECTS OF ELEVATION ON READING
  The elevation of the conductive layer in the sensor gap affects the meter readings. This effect can be addressed through the use of a stage, automatic compensation with a distance detector, or calibrating the meter to expect the material at a known elevation.
