Manual

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

conductivity of dialysate, the solution type MUST be set to the NaCl

conversion factor.

• Ifthe propersolutiontype isnotselected(the NaCliconis not

displayed), see Procedure to Select a Solution, pg. 15.

b. RES Key

A press of displays resistivity with units on the right. On the left

is shown solution type selected for resistivity (ref. Solution Selection,

pg. 15). The range of display of resistivity is limited to between 10

kilohms(KΩ)and30megohms(MΩ).Asolutionoutsidethatrangewill

only show [- - - -] in the display.

c. TDS Key

A press of displays Total Dissolved Solids with units on the right.

This is a display of the concentration of material calculated from

compensated conductivity using the characteristics of a known material.

On the left is shown solution type selected for TDS (ref. Solution

Selection, pg. 15).

3. pH and ORP Keys (D-6)

WARNING: When using a Digital Dialysate Meter™ to test the pH of

dialysate, ALWAYS perform a calibration check of the pH sensor at

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

your clinic’s internal procedures.

• SeeCheckingpH/ORPSensorPerformance,pg.34,forinstructions.

Measurements are made on solution held in the pH/ORP sensor

well. The protective cap is removed and the pH/ORP sensor well and

conductivitycellarelledandrinsedwiththesampleenoughtimesto

completely replace the storage solution.

WARNING: Because pH measurements require temperature

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

conductivity cell with sample.

• TheDigitalDialysateMeter’s™temperaturesensorislocatedin

the conductivity cell.

Afteruse,thepH/ORPsensorwellmustberelledwithMyronLStorage

Solution, and the protective cap reinstalled securely (ref. Maintenance of

the pH/ORP Sensor, pg. 12 and Cleaning Sensors, 3. pH/ORP, pg. 35).

a. pH Key (D-6)

A press of displays pH readings. No units are displayed on the

right.

b. ORP Key (D-6)

A press of displays Oxidation-Reduction Potential/REDOX

reading in millivolts (DEFAULT) or ppm depending on units selected;

“mV” or “PPM” is displayed.
