SAFETY INFORMATION

Please follow the guidelines below, and read this manual in its entirety to

ensure safe operation of the unit.

Avoiding Damage to the Instrument - Precautions

The Instrument Case

Though the instrument is housed in a water-proof IP67 case, DO NOT use

it underwater. The cable connector is not waterproof unless the cap is

installed. In case of submersion without the cap connected, follow these

steps immediately:

1. Remove the battery and reinstall the battery cover.

2. Dry the connector if necessary, and replace the DO probe. Rinse unit

carefully with distilled water. After rinsing and drying, inspect and

clean connectors to remove all contaminants that may affect probe

connections.

3. Wait for unit and all connections to dry before reinstalling the battery

and resuming operation.

4. If the unit does not function correctly after step 3, contact YSI for

possible repair or replacement.

The Probe

1. Membranes last longer if properly installed and regularly maintained.

Erratic readings can result from damaged or fouled membranes or

from large bubbles in the electrolyte reservoir. If unstable readings

or membrane damage occurs, replace both the membrane cap

and Oxygen Probe solution (also known as “O2 Probe Electrolyte”,

potassium chloride, or KCl solution). The average replacement

interval is 4 to 8 weeks, although they may last longer if kept clean.

Harsh environments, such as wastewater, may require membrane

replacement every 2 to 4 weeks. Unstable readings may occur if

membrane cap is coated with oxygen consuming or oxygen evolving

organisms such as bacteria or algae.

2. Chlorine, sulfur dioxide, nitric oxide and nitrous oxide can affect

readings by behaving like oxygen at the probe.

3. Avoid substances that may damage probe materials such as

concentrated acid, caustics and strong solvents. Probe materials

include Stainless steel, epoxy and ABS Plastic.

4. Keep the probe’s gold cathode clean and textured (when properly

maintained it has a matte finish). If it is tarnished (from contact with

606035REF-B-YSI-DO200A-DO200M-User-Manual-English.indd 1 12/7/2017 9:45:08 AM

certain gases), or plated with silver (from extended use with a loose

or wrinkled membrane), then clean it, following the instructions in the

Maintenance section.

5. To prevent the membrane and electrolyte from drying out, store the

field probe in the calibration bottle with the moistened sponge. If

using the self-stirring 200-BOD probe for the lab, store it in a clean

BOD bottle with 1 inch of water to keep the probe in a saturated air

environment.

UNPACKING

Carefully unpack the unit and accessories, and inspect for shipping

damages. Compare received parts with materials listed in the Package

Contents section. Notify YSI immediately of any damage or missing parts.

Save all packing materials until satisfactory operation is confirmed.

INSTALLATION

Probe Preparation

The DO probe ships with a dry, protective membrane. To install a new

membrane cap on the probe:

1. Unscrew probe membrane cap and discard.

2. Fill a new cap with Oxygen Probe Solution. Prepare according to

directions on the solution bottle.

3. Thread filled membrane cap onto sensor. The sensor can be placed

in a 100% water-saturated air environment (see Dissolved Oxygen

Calibration section).

4. Allow sufficient warm-up time for initial use (10-15 min). During this

time an “ovEr” message may appear on the display. This is normal.

After the warm up is complete the message will disappear.

Battery Installation

An initial display of “BAT” on the LCD indicates approximately one hour of

battery life for unit operation within specifications. Replace battery when

“BAT” appears on the LCD.

To replace battery, remove the two battery

cover screws and the battery cover and o-ring

(Figure 1). Replace the 9V battery. Replace

the battery cover and o-ring (be sure to align

the o-ring correctly to prevent a bad seal) and

fasten the two battery cover screws for the

splash-resistant feature.

Battery Disposal

This instrument is powered by a 9 volt battery, which the user must remove

and dispose of when the batteries no longer power the instrument.

Disposal requirements vary by country and region, and users are expected

to understand and follow the battery disposal requirements for their

specific locale.

INTENDED USE AND GENERAL

OVERVIEW

The YSI DO200A and YSI DO200M are precise water quality instruments

that measure dissolved oxygen (DO) in addition to temperature. A built-

in microprocessor stores, calculates, and compensates for all parameters

related to DO determinations including DO electrode temperature

characteristics.

The DO200A and DO200M have a waterproof IP67 case when the

connector cap is installed. The keys are highly reliable with tactile and

audio feedback. These instruments use one 9V battery. Recalibration is

not required when power is restored.

The front of the instrument has a large LCD that displays temperature and

either DO % or DO mg/L (ppm). The instrument also displays user prompts

and mode indicators. The unit prompts the user through calibration and

measurement procedures.

The model DO200A/DO200M field and lab probes use a polarographic

electrode with convenient screw-on cap membranes. Field probes feature

a built-in temperature probe for automatic temperature compensation, as

well as a stainless steel body for added weight. The self stirring 200-BOD

lab probe (item # 609200) is also available.

Key differences between the YSI DO200A and DO200M include:

• DO200A can store 50 data sets, while the DO200M can store 250 data

sets.

• A real-time clock is included on the DO200M for date/time stamp of

saved data.

• The DO200M features a waterproof USB port with cover that will allow

customers to download stored measurement data to a PC.

• A recal prompt on the DO200M allows users to select a recalibration

interval.
