3.
Rinse pH/ORP sensor well and conductivity cell 3 times with
acid or base buffer solution.
4.
Refill pH/ORP sensor well and conductivity cell again with
same buffer solution.
5.
Press
or
until display agrees with buffer value.
6.
Press
to accept 2nd point of calibration. Now the
display indicates the next type of buffer to be used.
Single point Gain Calibration is complete. Continue for the 3rd point of
Calibration (2nd Gain).
DO NOT press any measurement keys as this will exit calibration. Exiting
causes the value accepted for the buffer to be used for both acid and
base measurements.
To continue with 3rd point calibration, use basic buffer if acidic buffer
was used in the 2nd point, or vice-versa. Again, match the display to the
known buffer value as in step 2 and continue with the following steps:
7.
Repeat steps 3 through 6 using opposite buffer solution.
8.
Press
to accept 3rd point of calibration, which
completes the Calibration procedure. Fill pH/ORP sensor
well and conductivity cell with Myron L Storage Solution and
replace protective cap.
6. ORP Calibration (D-6)
ORP electrodes rarely give false readings without problems in the
reference electrode. For this reason, and because calibration solutions
for ORP are highly reactive and potentially hazardous, your Dialysate
Meter has an electronic ORP calibration. This causes the zero point on
the reference electrode to be set whenever pH 7 calibration is done.
7. Temperature Calibration
Temperature calibration is not necessary. The Dialysate Meter temperature
sensing circuit uses a high quality sensor that does not require calibration.
