CFEZ/MSEZ/D25NC/STHT Signal Level Diagnostic Test in EZMQC

Follow
  1. Connect instrument to EZMQC.
  2. In EZMQC, Go to Sensor --- Diagnostic --- Hardware Checks. Then “Sensor Diagnostic Test” dialog will pop out.
  3. Click “Signal Level”. Put the instrument white tile on the reflectance sample port. For CFEZ, make sure to use large view area port plate. De-select “Graphic Display” and “Raw Data Table”
  4. Click on “Flash” button. Instrument will take a reflectance measurement and display data in the table form. Six items will be filled in the table for both the monitor and samples channels, including Max Counts, Min Counts, Average Counts, Maximum Pixel, Dark Count Max, and Dar Count Min.

 

Pay attention to the monitor and sample Max Counts’ values. Max Counts are the peak values for the sample and monitor channel. With the instrument white tile, the Max Counts values should not below 15000, and are generally in the certain range for these instruments (Table-1). Also, the monitor channel value is typically within 80% -120% of the sample channel value. If the values of the sample and Monitor fall outside of these bounds, the instrument may not work properly.
