Two-point Calibration

Step Action
1 Ensure that
• the calibration default settings are correct
• "Percent" is set as the Redox unit in the configuration of the Re-
dox measurement input.

Chapter 13.2.2 "Calibration default settings for Redox sensors",
page 64.

Chapter 10.6.4 "pH/Redox/NH3 analysis inputs", page 21
2 Start the two-point calibration.
for redox sensors on analysis inputs:
Device Menu > Calibration > Select Analysis Input for pH/redox/
NH > Two-Point Calibration
3
for redox sensors with JUMO digiLine electronics:
Device Menu > Calibration > Digital Sensor 1 to 6 > Two-Point
Calibration
3 Enter the concentration value of the first reference solution in per-
cent. Confirm by pressing "OK".
Tap button to
enter field
4 Clean the Redox electrode and immerse it in the first test solution.
Wait until the measured value displayed stabilizes and then con-
firm the result of the measurement by pressing "OK".
5 As in step 3, enter the concentration value of the second solution
in percent. Confirm by pressing "OK".
6 Clean the Redox electrode and immerse it in the second
test solution. Wait until the measured value displayed stabilizes
and then confirm the result of the measurement by pressing "OK".
7 A protocol summarizing the calibration values determined then ap-
pears. Acknowledge the protocol by pressing "OK".
Failed calibrations are canceled at this point and discarded.
8 Press "Yes" to accept the Calibration values determined and enter
the Calibration in the Calibration logbook.
Press "No" to discard the results.
