INTRODUCTION

Thank you for purchasing the YSI Pro20/Pro20i, an instrument from the

YSI Professional Series product family. The Pro20 features user-replaceable

cables, while the Pro20i features an integral (i.e. built-in) cable. Sensors

are user-replaceable on Pro20 and Pro20i cables.

The Pro20/Pro20i features an impact resistant and waterproof (IP-

67) case, backlit display, user-selectable sensor options, internal

barometer, and a rugged, rubber over-mold case.

The Pro20/Pro20i provides valuable instructions and prompts near

the bottom of the display that will guide you through operation and

use. However, reading the entire manual is recommended for a better

understanding of the Pro20/Pro20i’s features.

GETTING STARTED

INITIAL INSPECTION

Carefully unpack the instrument and accessories and inspect for

damage. Compare received parts with items on the packing list. If

any parts or materials are damaged or missing, contact YSI Customer

Service at 800-897-4151 (+1 937 767-7241) or the authorized YSI

distributor from whom the instrument was purchased.

BATTERY INSTALLATION

The instrument requires 2 alkaline C-cell batteries. Under normal

conditions, the average battery life is 400 hours at room temperature

without using the back light. A battery symbol will blink in

the lower, left corner of the display to indicate low batteries when

approximately 1 hour of battery life remains.

To install or replace the batteries:

1. Turn the instrument off and flip over to view the battery cover

on the back.

2. Unscrew the four captive battery cover screws.

The Pro20/Pro20i can not communicate to a PC via a Pro Plus

communications saddle. Connecting the Pro20/Pro20i to a

communication saddle may cause erratic instrument behavior.

3. Remove the battery cover and remove the old batteries if

necessary.

4. Install the new batteries, ensuring correct polarity alignment

(figure 1).

5. Place the battery cover on the back of the instrument and

tighten the four screws. Do not over-tighten.

Figure 1. Pro20/Pro20i with battery cover removed.

Notice battery symbols indicating polarities.

The waterproof instrument case is sealed at the factory and

is not to be opened, except by factory-authorized service

technicians. Do not attempt to separate the two halves of the

instrument case as this may damage the instrument, break the

waterproof seal, and will void the warranty.

CONNECTING THE SENSOR AND CABLE

CONNECTING THE SENSOR

“Sensor” refers to the removable portion or electrode sensing portion

of the cable assembly, i.e. the dissolved oxygen sensor. “Bulkhead”

refers to the portion of the cable with the single-pin connector (Figure

3).

The Pro20/Pro20i has two compatible sensors for use with a field cable:

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 about the differences on the two sensor types, see

Sensor Type in the System Setup menu section and/or the Principles of

Operation section of this manual.

If using a ProBOD sensor/cable assembly, there is no need to install a

sensor because it has a built in Polarographic dissolved oxygen sensor.

Before installing either sensor or connecting the cable (Pro20

only) 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 it

is powered on. See the System Setup menu section of this

manual for instructions on configuring the Sensor Type after

the first power on.

1. Ensure both the sensor connector and sensor port on the cable are

clean and dry.

2. Grasp the sensor with one hand and the cable bulkhead in the

other.

3. 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.

4. Twist the sensor clockwise to engage 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.
