IV. INITIAL CALIBrATION and FACTOrY SETTINGS
CAuTION: The factory settings are not intended to replace calibration
with reference solution/buffers.
Factory settings do not take into account the current condition of
the actual sensor installed in your instrument or any environmental
conditions that might exist in your facility.
• DO NOT use a Digital Dialysate Meter™ to check the pH or
conductivity of dialysate using factory calibration settings.
• ALWAYS perform an initial calibration of a Digital Dialysate
Meter™ with reference solutions/buffers prior to putting it into use
for the first time.
The following table lists initial calibration procedures and their location
in this manual.
PARAMETER PROCEDURE REFERENCE SOLUTION
General instructions (see Calibration, pg. 16)
Conductivity
Gain 14.00 mS NaCl 1 (see Conductivity or
TDS Calibration, pg. 19)
Resistivity Electronically calibrated with Conductivity Gain
TDS Gain 442™ 1 (see Conductivity or TDS
Calibration, pg. 19)
3000 PPM
1 (see Conductivity or TDS
Calibration, pg. 19)
pH Zero Point 7.0 pH (see pH Zero Calibration
(D-6), pg. 20)
Gain – Acid 4.0 pH (see pH Gain Calibration
(D-6), pg. 21)
Gain – Base 10.0 pH (see pH Gain Calibration
(D-6), pg. 21)
ORP Electronically calibrated with pH Zero Point
Temperature Does not require calibration
1 Make sure the correct solution type is selected and that it matches the type of
reference solution being used (see Solution Selection, pg. 15)
Avoid letting solvents come into contact with the instrument’s sensors,
case or window areas. Shock damage from a fall may cause the
instrument to fail.
WArNING: You MuST verify the function and calibration of any Dialysate
Meter that has been dropped by performing calibration checks (see
Checking pH/ORP Sensor Performance, pg. 34) of all measurement
functions prior to putting it back into use.
