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 filled and rinsed with the sample enough times to
completely replace the storage solution.
WArNING: Because pH measurements require temperature
compensation, ALWAYS fill 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 refilled 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.
