ESR Statistics screens

A statistical graph is produced over a selected period. Make a selection of the following graphs;

• Daily mean (mm)
  Use this to check variations in the daily mean ESR.
  
• Hazy (%)
  Increasing hazy aspects are an indication for contamination of the instrument, see Aspect Hazy
  
• Dilution (%)
  Increasing dilution errors indicate the need for maintenance of the diluter system.
  
• Bubbles on top (%)
  Increasing samples with bubbles indicate the need for maintenance of the aspiration system, see Foam in column
  
• ESR errors (%)
  Increasing ESR errors may indicate the need for maintenance, see ESR Error
  
• Number of samples
  This can be used to document variations in work load.
