PROBE MODE
7.2. pH CALIBRATION MESSAGES
Clean Probe:
The "Clean Probe" message indicates poor electrode
performance (offset out of accepted window, or slope under the
accepted lower limit). Often, cleaning the probe will improve
the pH electrode's response. See pH Electrode Conditioning and
Maintenance for details. Repeat calibration after cleaning.
Check Probe & Buffer:
The “Check Probe & Buffer” message appears when there
is a large difference between the pH measurement and the
selected buffer value, or the electrode slope is outside of the
accepted slope limit. You should check your probe and confirm
the correct buffer selection. Cleaning may also improve this
response.
Wrong Temperature:
The buffer temperature is too extreme for the selected buffer value.
7.3. pH MEASUREMENT
The HI83303 can be used to perform direct pH measurements by connecting a HANNA
®
digital
pH electrode with a 3.5 mm TRRS connector. To begin taking probe measurements, connect the
electrode to the 3.5 mm port marked with EXT PROBE located at the rear of the meter. If the meter
is in “Photometer Mode”, set the meter to “Probe Mode” by pressing the MODE key.
While taking pH probe measurements, the following functions are available:
Calibrate: Press to access electrode calibration functions.
GLP: Press to review the last calibration information, including date/time, buffers used, slope,
and offset.
Range: Press to switch between “pH” units and “mV” units.
