CALIBRATION
CAUTION! Writing to server is currently not allowed. This prevents calibration data from saving. First change the server write access in 'Settings'.
Select a type of calibration:
Calibrate at pH 7 and at either pH 4 or pH 10.
Number of points - as needed but at least 2 different.
Enter the isopotential data and measure one buffer.
2-points calibration. Step 1.
  1. Rinse the pH and temperature sensors with clear water.
  2. Put both sensors in a vessel with fresh pH7 buffer.
  3. Wait until all readings get stable.
  4. Press the button "Go To Step 2".
2-points calibration. Step 2.
  1. Rinse the pH and temperature sensors with clear water.
  2. Put both sensors in a vessel with fresh buffer of either pH4 or pH10 and select the buffer accordingly.
  3. Wait until all readings get stable.
  4. Press the button "Calibrate".
Multipoint calibration. Step 0.
Points passed:
  1. Select a buffer to measure:
  2. Rinse the pH and temperature sensors with clear water.
  3. Put both sensors in a vessel with fresh quantity of the selected buffer.
  4. Wait until all readings get stable.
  5. Press "Next Buffer" or press "Calibrate" to finish.
Isopotential point calibration. Step 1.
Enter valid values for the isopotential point. Then press the button "Go To Step 2" to determine the slope.

Isopotential point calibration. Step 2.
  1. Select a buffer to measure at least 2 pH units away form the iso-point:
  2. Rinse the pH and temperature sensors with clear water.
  3. Put both sensors in a vessel with fresh quantity of the selected buffer.
  4. Wait until all readings get stable.
  5. Press the button "Calibrate".
