8.4 Select Electrode Type
This screen allows you to select the type of electrode that is specific
for your ion of interest. Your choice of electrode informs the meter
which default slope to use in the calculations made for the electrode
efficiency and sample concentration. Once you have selected an
electrode, you will not be required to enter the default slope
numerically.
Note:
The default slope value specific for the electrode that you choose is a
theoretical slope value that is used in the calculations to determine
the efficiency of your electrode. This slope value is not the slope
value that is displayed in the data box of the measurement screen.
You will still need to standardize the meter using ion standards to
determine the actual efficiency of your electrode.
To Select Electrode Type
1. Access the Select Electrode Type screen from the Ion Setup
screen. The current units are displayed on the screen.
2. Use the arrow keys to highlight the desired units.
3. Touch enter to accept Electrode Type and return to the Ion Setup
screen.
OR
Touch exit to return to the ion setup screen, without making any
changes
