Battery Installation
Sensor Installation and Cable
Connection
The ProQuatro requires (2) alkaline C-cell batteries which are included with the
purchase of a new instrument. Battery life depends on parameters and usage.
Under normal conditions, battery life is approximately 80 hours for continuous use
at room temperature. To install or replace the batteries:
1. Turn the instrument over to view the battery cover on the back.
2. Unscrew the four captive battery cover screws.
3. Remove the battery cover and instal the new batteries, ensuring correct
polarity alignment (Figure 1).
4. Replace the battery cover on the back of the instrument and tighten the
four screws. Do NOT over-tighten.
There are multiple cables and sensors that can be used with the ProQuatro. Please refer to the following sections to ensure the
correct cables and sensors are used with the instrument.

indicating polarities.

Field Cables and Sensors
Most field cables have at least one sensor port in which a sensor must be installed. Ports on these cables are sensor-specific, so it is
important to ensure the correct sensor is installed in each port. Available field cables are listed in the table below:
Throughout the manual, the term “sensor” refers to the removable portion or electrode sensing portion of the cable assembly. For
example, the DO sensor or pH sensor is the part that can be removed from a field cable and replaced with a new sensor. Sensors
that are available for field cables include:
ISE (Ion Selective Electrode) notates a port that can accept pH, ORP, Ammonium, Nitrate, Chloride, and, in some
cases, a pH/ORP combination sensor (6051030 and 6051020 cables only).

Dual sensor bulkhead ports are numbered 1 and 2, see figure 2
below. Please refer to the following tables to determine correct
sensor installation.
The Quatro cable bulkhead ports are labeled 1, 2, DO, and CT, see
figure 3 below. All sensors except the Conductivity/Temperature
sensor can be installed following directions in the section Sensor
Installation – All Sensors Except the Conductivity/Temp Sensor. The
Conductivity/Temperature sensor can be installed using directions
in the section Sensor Installation – Conductivity/Temp Sensor in a
Quatro Cable. For ease of installation, YSI recommends that you install
a sensor into port 1 first; followed by DO installation, then port 2, and
lastly C/T.

*A sensor must be installed in port 1 for correct operation. If you install a pH/ORP combo sensor into a 6051010
cable, ORP will not be measured. It is not recommended to use a pH/ORP combo sensor on a 6051010 cable.
If using a 605103 pH/ORP combination probe with a 6051020 or 6051030 cable, you can report both pH and ORP.
However, it is recommended to set ISE1 as pH and ISE2 as ORP in the Sensor Setup menu.

Figure 4 The image on the left shows a clean, dry sensor being aligned with the bulkhead. On the right, the sensor has been
pushed into the bulkhead and is being screwed into place.
*If using a Quatro cable, a sensor must be installed in port 1 for correct operation of port 2. If you install a pH/ORP
combo sensor into a Quatro cable, ORP will not be measured. It is not recommended to use a pH/ORP combo
sensor on a Quatro cable.
Before installing a dissolved oxygen sensor and connecting the cable to the ProQuatro, the ProQuatro must be
configured for the sensor being installed. See the Dissolved Oxygen Sensor Setup section of this manual for
instrument configuration instructions. Failure to do this may result in damage not covered under warranty.
Sensor Installation - All Sensors Except the Conductivity/Temp Sensor
First, ensure both the sensor connector and sensor port on the cable are clean and dry. To connect the sensor, grasp the sensor
with one hand and the sensor connection end of the cable (bulkhead) in the other. Push the sensor into the connector on the cable
until it is properly seated and only one o-ring is visible. Failure to properly seat the probe may result in damage. Twist the sensor
clockwise to engage threads and finger tighten (Figure 4). DO NOT use a tool. This connection is waterproof. Please refer to the
sensor installation sheet that is included with each sensor for detailed instructions.

Sensor Installation - Conductivity/Temp Sensor in a Quatro Cable
As mentioned, the installation of the Conductivity/Temperature (C/T) sensor (model 5560) in a Quatro cable is different from all
other Pro Series sensor installations. Follow these instructions when installing a conductivity/temperature sensor in a Quatro cable:
1. Locate the C/T port and, if replacing, remove the old sensor using the installation tool to loosen the stainless steel retaining
nut. Once the stainless steel retaining nut has been completely unscrewed from the bulkhead, remove the old sensor from
the bulkhead by pulling the sensor straight out of the bulkhead.
2. Apply a thin coat of o-ring lubricant (supplied with the sensor) to the o-rings on the connector side of the new sensor.
Port Plug Installation
3. Align the connectors of the new sensor and the port. With connectors aligned, push the sensor in towards the bulkhead until
you feel the sensor seat in its port. You will experience some resistance as you push the sensor inward, this is normal.
4. Once you feel the sensor seat into the port, gently rotate the stainless steel sensor nut clockwise with your fingers. DO NOT
use the tool.
5. The nut must be screwed in by hand. If the nut is difficult to turn, STOP, as this may indicate cross threading. DO NOT cross
thread the sensor nut! If you feel resistance or cross threading at any point, unscrew the nut and try again until you are able
to screw the nut down completely without feeling any resistance. Damage to your cable/ sensor may occur if you force the
parts together.
6. Once completely installed, the nut will seat flat against the bulkhead. At this point, use the tool that was included with the
sensor to turn the nut an additional ¼ to ½ turn (Figure 5). DO NOT over tighten.
Please refer to the sensor installation sheet that is included with the conductivity/temperature sensor for detailed instructions.
Visually inspect the port for moisture. If moisture is found, it must be completely dried prior to sensor installation.
When a sensor is not installed, the sensor and cable sensor connectors are NOT water-proof. Do not submerge the
cable without a sensor or port plug installed in all available ports.
Figure 5 Installation tool used to tigthen the
stainless steel retaining nut of the C/T sensor.
As necessary, install a port plug into any port that does not have an installed sensor. This will protect the bulkhead from water
damage. Port plugs and a tube of o-ring lubricant are included with all Quatro cables. These items can be ordered separately if
needed. To install a port plug, apply a thin coat of o-ring lubricant to the two o-rings on the port plug. After application, there should
be a thin coat of o-ring lubricant on the o-rings. Remove any excess o-ring lubricant from the o-ring and/or port plug with a lens
cleaning tissue. Next, insert the plug into an empty port on the bulkhead and press firmly until seated. Then, turn the plug clockwise
to engage the threads and finger-tighten until the plug is installed completely. DO NOT use a tool to tighten the plug.

Laboratory Cables and Sensors
There are several cable assemblies with built-in sensors that are ideal for use in a laboratory environment. These assemblies include:
YSI Item # Description
605780 DO/Temp 115V stirring BOD probe with 1-meter cable assembly
605107 pH/Temp single junction combination electrode with 1-meter cable
605177 pH/Temp single junction combination electrode with 4-meter cable
605108 ORP/Temp single junction combination electrode with 1-meter cable
605178 ORP/Temp single junction combination electrode with 4-meter cable
605109 pH/ORP/Temp single junction combination electrode with 1-meter cable
605179 pH/ORP/Temp single junction combination electrode with 4-meter cable
The military-spec (MS) cable connectors are keyed for positive mating and to prevent connector damage (Figure 6). The handheld
retains its IP-67 waterproof rating when the cable is disconnected. However, the connectors are not wet-mateable and should be
clean and dry before connecting.
Align the keys on the cable connector with the slots on the handheld connector. Push together firmly, then twist the outer ring
clockwise until it locks into place.
