Manual

I. GENERAL WARNINGS AND CAUTIONS

For your own safety and the safety of your patients follow these

important safety instructions as well as other safety instructions noted

throughout this operation manual.

WARNING: statements alert the user that serious adverse reactions for

the patient are associated with related use or misuse.

CAUTION: statements alert the user that the related use or misuse of

the device could cause it to be damaged or malfunction.

WARNING: Read this entire operation manual before using a Digital

Dialysate Meter™.

WARNING: When using a Digital Dialysate Meter™ to check the

conductivity or pH of dialysate, ALWAYS perform a calibration

check of the instrument for those measurement functions at the

beginning and end of each work day or more often if required by

your clinic’s internal procedures.

• SeeCalibration,pg.16,forinstructions.

WARNING: When using a D-6 to verify the complete removal of residual

oxidizing germicides, such as chlorine, ORP mV reading should be

as low as possible. Generally, an ORP reading of < 275 mV is a good

indicator that there is very little residual oxidizer remaining. However,

it is recommended that a target reading matching or close to the ORP

value measured at the output of your RO system be sought.

WARNING: Because pH measurements require temperature

compensation, ALWAYSllboththepHsensorwelland

conductivity cell with sample.

the conductivity cell.

WARNING: When measuring with a Digital Dialysate Meter™, DO

NOT press the CAL key unless instructed to by a procedure in this

manual.

(the word CAL will appear at the top of the display) and could

inadvertently change the calibration of the instrument and alter

the accuracy of measurements.
