- This will open the following screen:
• Plug the pH electrode at the rear panel of the
Mütek™ PCD-05 (1, Fig. 3-3).
• Remove the electrode cap and rinse the electrode
with deionized water.
• Immerse the pH electrode in the pH 7.00 buffer
solution and select "Start".
• Wait until the displayed mV value has stabilized and
select "OK".
- Depending on your preselection, one of the follo-
wing screens will come up:
• Rinse the electrode with deionized water again.
• Then immerse the pH electrode in a buffer solution
with pH 4.01 for acid range or pH 9.21 for alkaline
range and select "Start".
• Wait until the displayed value has stabilized and
select "OK".
This brings up the following screen:
- Confirm calibration by pressing "Start".
• Repeat calibration if the slope is beyond the range
of -50 and -65 mV/pH.
