From measurement mode:
1. Press the MODE key to select the
mg/l (ppm) measurement mode.
2. Press the SETUP key to enter SETUP
mode.
3. Press the ▲ and ▼ keys to scroll
through subgroups until you view
parameter P3.0 in the lower display.
See figure
4. Press the ENTER key. The upper
display shows the probe slope.
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 P3.0. If you want to return to
measurement mode, press CAL/MEAS.
mg/l (ppm) mode—P3.0: 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%).
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.

mg/l (ppm) mode—P4.0: Unit configuration
Unit configuration mode lets you select the following parameters:
A. Ready indicator and auto endpoint function
B. mg/l or ppm units
C. Temperature in °C or °F
P4.1: 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.

2. Press 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 to select
parameter P4.0 “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 proceed to P4.2 on page 52. Or,
press the CAL/MEAS key twice to return
to measurement mode.
Notes: Meter default is set for Ready indica-
tor 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 P5.1 on page
43 in % saturation mode. Any changes you
make to the Ready indicator/ auto endpoint
function in % saturation mode will also
change in pH and % saturation modes.
