When a port is empty on the cable, the bulkhead connector is
not water-proof. Do not submerge the cable without a sensor
installed! Submerging the cable without a sensor installed
may cause permanent damage to the cable that is not covered
under warranty. Install a YSI ProSeries port plug into the port if
not installing a sensor in either port.
Figure 3.
The Pro1020 bulkhead sensor ports are numbered 1 and 2.
Port 1 is for pH or ORP. Port 2 is for Dissolved Oxygen.
INSTALLING THE ISE SENSOR
The Pro1020 has three compatible ISE sensors: pH (model #1001), pH-
amplified (model #1001A) and ORP (model #1002).
Sensor Installation:
1. Locate port 1 on the cable’s bulkhead, see figure 3.
2. If using the cable for the first time, remove the plastic plug from the
cable’s bulkhead port by pulling it straight out of the port. This can
be discarded. Otherwise, remove the old sensor.
3. Ensure both the sensor connector and bulkhead connector are
clean and dry.
4. Grasp the sensor with one hand and the cable bulkhead in the
other.
5. Push the sensor into the connector on the cable until it is firmly
seated with only 1 o-ring visible. Failure to properly seat the sensor
may result in damage.
6. Twist the sensor clockwise to engage the threads and finger
tighten. Do NOT use a tool. This connection is water-tight.
7. If using the 1001A, install the guard extender (included in 605216
kit) onto the bulkhead prior to installing the sensor guard or
calibration cup.
The ISE sensor is shipped with the tip in a storage bottle. To remove,
twist the bottle off the lid and remove the bottle from the sensor. Next,
remove the o-ring and slide the lid off the sensor.
INSTALLING THE DISSOLVED OXYGEN SENSOR
Before installing a sensor or connecting the cable to the
instrument, the Sensor Type must be configured for the
sensor being installed/connected. Failure to do this may
result in damage not covered under warranty. The instrument
will step you through this setup the first time the instrument
is powered on. See the System Setup Menu section of this
manual for instructions on configuring the Sensor Type after
the first power on.

The Pro1020 has two compatible dissolved oxygen sensors:
Polarographic
– This sensor has a black sensor body and is engraved
with the model number 2003. Polarographic will be abbreviated Polaro
in the instrument’s menu.
Galvanic
– This sensor has a grey sensor body and is engraved with the
model number 2002.
For information on the differences between these two types of sensors,
see Sensor Type in the System Setup Menu section of this manual.
Installation:
1. Locate port 2 on the cable’s bulkhead, see figure 3.
2. If using the cable for the first time, remove the plastic plug from the
cable’s bulkhead port by pulling it straight out of the port. This can
be discarded. Otherwise, remove the old sensor.
3. Ensure both the sensor connector and bulkhead connector on the
cable are clean and dry.
4. Grasp the sensor with one hand and the cable bulkhead in the
other.
5. Push the sensor into the connector on the cable until it is firmly
seated and only 1 o-ring is visible. Failure to properly seat the
sensor may result in damage.
6. Twist the sensor clockwise to engage the threads and finger
tighten. Do NOT use a tool. This connection is water-tight.
For more detailed instructions, please refer to the sensor installation
sheet that is included with each sensor.
