From your knowledge of expected concentrations, use the table below to determine which
settings are appropriate:
Use Total LR or Strong LR for waters acidity in the 15 - 500 mg/L range.
Use Total HR or Strong HR for waters acidity in the 400 - 4000 mg/L range.
Use the appropriate titrant for each range.
Also, the pump must be recalibrated when the measurement range is changed.
