From measurement mode:
1. Press the MODE key to select the
% saturation measurement mode.
2. Press the SETUP key to enter SETUP
mode.
3. Press the ▲ and ▼ keys to scroll
through subgroups until you view
parameter P4.0 in the lower display.
See figure
4. Press the ENTER key. The upper
display shows the probe slope.
See figure
5. Press the ENTER key. The upper
display shows the % saturation offset.
See directions for setting this offset on
page 40.
See figure
6. Press the ENTER key. The upper
display shows the 100 % saturation mV
value.
See figure
7. Press the ENTER key. The upper display
shows the 0 % saturation mV value.
See figure
8. Press the ENTER key to move back to
subgroup P4.0. If you want to return to
measurement mode, press CAL/MEAS.
% saturation mode—P4.0: Electrode properties
These “view only” parameters show the electrode properties for diagnostic purposes:
probe slope: shows the calibration slope of the probe. This mode displays slope
from 0.5 to 1.999 % of slope (1.0 = 100%).
% saturation offset: shows the value of the % saturation offset entered in parameter
P2.0 (see page 40 for instructions).
100% saturation mV value: shows the
sensor’s mV output corresponding to
100% saturation.
0% saturation mV value: shows the
sensor’s millivolt output corresponding
to 0% saturation.

From measurement mode:
1. Press the MODE key to select the
% saturation measurement mode.
2. Press SETUP key to enter SETUP mode.
3. Press the ▲ and ▼ keys to scroll through
subgroups until you view parameter P5.0
in the lower display.
See figure
4. Press the ENTER key to select
parameter P5.1 “rdY”(Ready).
See figure
5. Press the ▲ and ▼ keys to select the
configuration you require.
•ON switches the READY indicator on.
•OFF switches the READY indicator off.
• ON and HOLD together switches the
auto endpoint feature on.
6. Press the ENTER key to confirm selection
and to move to step 3 on page 44 (P5.2).
Or, press the CAL/MEAS key twice to
return to measurement mode.
NOTES: Meter default is set for Ready indi-
cator on, and auto endpoint function off.
You can also change the Ready indicator and
auto endpoint function in SETUP Program
P3.1 on page 35 in pH mode or P4.1 on page
51 in mg/l (ppm) mode. Any changes you
make to the Ready indicator/ auto endpoint
function in % saturation mode will also
change in pH and mg/l (ppm) modes.
% saturation mode—P5.0: Unit configuration
Unit configuration mode lets you select the following parameters:
A. Ready indicator and auto endpoint function
B. Temperature in °C or °F
P5.1: READY indicator and auto endpoint function
The first program lets you select:
• “READY indicator on” to indicate when the reading is stable.
• “READY indicator off” for faster meter response.
• Auto endpoint function on. Select auto endpoint on to “hold” the reading when
it is stable for more than 5 seconds. The display automatically freezes, and the
HOLD indicator appears on the left side of the display. Press the HOLD key to
release the display and access other functions.
