8.6 ELE: Electrode Properties
These “view only” parameters show you the electrode properties
for diagnostic purposes:
A. Probe Slope: Lets you view and give an indication of the
probe’s efficiency. The value displayed is the ratio of the
theoretical value to the actual value produced by the probe.
The higher the number, the lesser output from the probe. The
ratio displays from 0.5 to 1.999.
B. % Saturation Offset: (available in % saturation SETUP mode
only): Lets you see the value of the % saturation offset entered
in parameter “OFS” (see page 24 for instructions).
C. 100% Saturation mV value: Lets you view the sensor’s mV
output corresponding to 100% saturation.
D. 0% Saturation mV Value: Lets you view the sensor’s millivolt
output corresponding to 0% saturation.
From measurement mode:
1. Press the MODE key to select the measurement mode for the
electrode properties you want to view: % or mg/L (ppm).
2. Press the SETUP key to enter SETUP mode.
3. Press MI/ or MR/ keys to scroll through main groups until
you view parameter “ELE” in the upper display.
4. Press the ENTER key. The upper display shows the probe
slope.
5. Press the ENTER key. The upper display shows the %
saturation offset. See directions for setting this offset on page
24. NOTE: This % saturation slope and offset appears only in
% saturation SETUP mode. If you are in mg/L (ppm) SETUP
mode, the meter skips step 4 and 5 to show step 6 on page 27. Figure 23: View electrode
