7.4 (ELE.3) Electrode Properties
This menu features data of the electrode properties for diagnostic purposes.
The “view only” parameters such as the electrode Slope Factor, % Saturation
Offset setting, 100% Saturation mV value and 0% Saturation mV value are very
useful in determining the life efficiency of the electrode. These electrode
properties can be examined through its data in % Saturation and mg/L (ppm)
Concentration which is available in their Set Up menu respectively.
7.4.1 Viewing the electrode Slope Factor
This parameter lets you view and gives an indication of the probe’s efficiency.
The value displayed is the ratio of the actual value produced by the probe to the
theoretical value. The higher the number, the lower the mV output from the
probe. The ratio displays from 0.5 to 1.999.
From the % Saturation or Temperature Set Up menu,
1) Enter the Set Up menu & scroll by using the ▲ and ▼ keys until the meter
displays the Electrode Properties menu “ ELE.3”
2) Press the HOLD/ENTER key to enter the menu and view the Slope Factor
of the electrode.
3) The display will momentarily shows “FACT” before displaying the slope
factor value.
7.4.2 Viewing the % Saturation Offset (Only available in % Saturation
or Temperature Set Up menu):
This parameter shows you the amount of the % Saturation Offset entered in the
other parameter “OFS” (refer to Section 7.7 for instructions).
From Step 3 above,
4) Press the HOLD/ENTER key to enter the % Saturation Offset viewing
menu.
5) The meter will display “OFS” momentarily before displaying the last offset
adjustment made.
