XI. CALIBrATION INTErVALS
The Dialysate Meter is designed to not require frequent recalibration. The
most common sources of error were eliminated in the design, and there
are no mechanical adjustments. Still, to ensure specified accuracy, any
instrument must be checked against chemical standards occasionally.
