5.0 pH Calibration
pH
calibration
is
important
before
first
use.
It
ensures
pH
measurements
and/or pH
stock solution dosing is accurate.
The
Bluelab
Temperature
Probe
DOES
NOT require calibration but is used for ATC.
The
pH
calibration
involves
cleaning
the pH probe tip and then calibrating in TWO
or THREE
SOLUTIONS
.
For accurate pH readings the pH probe should be cleaned, and calibration
carried out when:
 The device is using factory defaults (the calibration indicators are not lit).
 30 days since the last pH calibration (calibration indicators are flashing).
 the reading is different to what you were expecting.
 the pH probe is replaced with a new one.
If the pH probe has been in use, it should be cleaned before pH calibration. See
section 6.2 for pH probe cleaning. New pH probes do not need to be cleaned.
If you are calibrating to TWO points, remember:
If a reading below pH 7.0 is expected, use pH 7.0 and pH 4.0 calibration solutions. If
a reading above pH 7.0 is expected, use pH 7.0 and pH 10.0 calibration solutions.
You would require calibration in THREE solutions if:
Readings above and below pH 7.0 are expected, use pH 7.0, pH 4.0 then pH 10.0
calibration solutions. You will need to enable 3-point calibration in the settings
menu.
5.1 How to perform a pH calibration
To
calibrate
the
pH
Clean pH & Temperature probe tips.
See section 6.2 on how to clean the pH
probe (the pH & Temperature probes
does not require cleaning before the first
use).
The calibration default is set at two-
point calibration. If a three-point
calibration is required view section
2.5.7.
