Ion Setup
ELECTRODE TYPE / MEASUREMENT UNITS
Select Electrode Type
This screen lets you 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 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 calucaltions 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.
Changing electrode type
will erase the previous
standardization.
To select electrode type:
1. Touch the Electrode Type box to view the list of electrodes.
2. Use the scroll bar to select the desired electrode type.
If you are using several different electrodes, you can create a
different User Profile for each electrode to save individual
parameters and calibration information (i.e. “Ammonia
Samples” or “Sodium Batch Testing”. See pages 95-97 for
directions on how to set up a user profile.
Select Measurement Units
This screen lets you select the units in which the meter will report the concentration of
the ion of interest. The current units are displayed on the screen.
To select measurement units:
1. Touch the Measurement Unit box to view the list of measurement units.
2. Use the scroll bar to select the desired units.
Once the unit has been calibrated with a particular unit of measurement, if an attempt is
made to change the units, the unit comes out with a warning message: “Changing the
measurement unit will erase previous standardization. Do you wish to continue?”
