6.3.3 Pre-Requisites /Things to Consider

  1. This particular setup can be used to measure transient currents.
  2. Set proper supply Voltage, Current and series resistor value before turning ON the supply Output.
  3. Make sure you select proper range in the “Range” tab before you start the measurements.
    1. There are three ranges: Low, Mid and HiGH. Select based on the requirement.
    2. Select the proper time and current divisions, these will be at top left and top right corner of plot window.
  4. Plot in the GUI might not match the current numbers due to software issue. But the Minimum, Average and Maximum values displayed at the bottom are accurate.
  5. In order to measure max current of particular spike/peak use marker, place markers on either side of the spikes and look for max currents.
  6. There is no necessity to tweak settings for the measurements accuracy. Hence Set it to default, software automatically sets the best possible accuracy with the current configuration.
  7. If you select the 4wire connection mode then software will take care of drop across the wire, there is no need to compensate for the drop across the wire.
