a. Press or .
b. Press .
c. Press key until “FAC” appears and release.
d. Press to accept the factory calibration setting.
4. pH Calibration (D-6)
ALWAYS calibrate a Digital Dialysate Meter™ pH function at Zero
Point with a pH 7.0 buffer solution BEFOrE performing either the
Acid or Base gain calibration.
• The Acid/Base gain calibrations may be done in either order.
Read Proper Handling of Reference Solutions, pg. 16, before
attempting pH calibration.
Calibrating the pH function of a Digital Dialysate Meter™ is a three-
step process. Zero Point calibration is always done first. Steps 2 and 3
can be performed in either order.
STEP 1: Zero Point Calibration (7.0 pH buffer)
STEP 2: Gain Calibration – Acid (4.0 pH buffer)
STEP 3: Gain Calibration – Base (10.0 pH buffer)
a. pH Zero Calibration (D-6)
1. Rinse pH/ORP sensor well and conductivity cell 3 times with 7
buffer solution.
2. Refill both sensor wells with 7 buffer solution.
3. Press to verify the pH calibration. If the display shows
7.00, skip the pH Zero Calibration and proceed to section b.
pH Gain Calibration, pg. 21.
4. Press to enter
calibration mode. The
“CAL”, “BUFFER” and “7”
annunciators will appear
(see Figure 5).
Displayed value will be the
uncalibrated sensor.
