3.4 pH or ORP Combination Probe connections and setup
The drawing shows the connections for the Aquametrix Combination probe. The cable should be run
in a conduit separate from AC power wires, and via a separate conduit hole. The cable length should
not exceed 10 feet (3 meters).
Fig. 3.3 Connections for the 2 and 4 wire Combination Probe
Once connected, step through the LCD menus to select the probe in the order shown. The first two steps
may be skipped if the meter is already configured for a Combination Probe. If a two wire pH probe is
used, which has no temperature sensor, ensure that the Temp. Comp. Override is set to same temper-
ature as the buffer before calibrating. If a two wire ORP probe is used, you can blank the Temp display
with the T DISP OVERRIDE menu.
The 2 wire version has
no temperature sensor
and is connected via a
coaxial wire.
In a pH meter, the user
should set the T COMP
OVERRIDE menu to ON
(Section 4.10) and adjust
the temperature setting to
the actual probe temper-
ature.
In an ORP meter, the
user should set the
T.DISP OVERRIDE to
ON (Section 5.9) to blank
the temperature reading
on the display.
The 4 wire version has
two additional wires for
the probe internal tem-
perature sensor. Ensure
that the T COMP OVER-
RIDE or T.DISP OVER-
RIDE is OFF.
