CO-220

Carbon Monoxide Meter

Instruction Sheet

Introduction

The CO-220 Carbon Monoxide Meter (hereafter referred to as

“the Meter”) detects the presence of carbon monoxide (CO) and

measures concentrations between 1-1000 parts per million

(PPM).

The Meter indicates the presence of carbon monoxide in two

ways:

•By a reading on the LCD in PPM.

•By a beeper tone.

Safety Information - Read First

⇒Do not use the Meter as a personal safety monitor.

⇒Learn and recognize the effects of CO poisoning.

0-1 PPM Normal background levels.

9 PPM ASHRAE Standard 62-1989 for living areas.

50 PPM OSHA enclosed space 8-hour average level.*

100 PPM OSHA exposure limit.*

200 PPM Mild headache, fatigue, nausea and dizziness.

800 PPM Dizziness, nausea and convulsions.

Death within 2 to 3 hours.

* U.S. Department of Labor, Occupational Safety & Health

Administration (OSHA) Regulation 1917.24:

The CO content in any

enclosed space shall be maintained at not more than 50 PPM

(0.005%). Remove employees from enclosed space if the CO

concentration exceeds 100 PPM (0.01 %).

What the Meter Does

The Meter indicates the presence of CO by a reading on the LCD

and a beeper tone.

Above 1000 PPM, the LCD reads “OL” to indicate an out of range

condition.

The beeper functions much like clicking of a Geiger counter:

•The higher the concentration of CO, the faster the beeper

sounds.

•Above 200 PPM, the beeper sounds continuously, while the

frequency of the tone increases with the concentration of CO.

Turning the Meter On

Install the battery. (See “Installing and Replacing the Battery.”)

To turn the Meter on, press the green button.

The Meter beeps twice, then performs a self-test. During the self-

test, the display counts down from “10” to “0”, while the Meter

emits a series of 2 beeps followed by a pause.

If the Meter passes the self-test, the Meter begins monitoring,

which is indicated by a beep every two seconds, and shows a

reading on the display.

CO-220 English Instruction Sheet

Self-Test

The Meter tests the sensor and the battery each time it is turned

on and continuously monitors the battery. If the battery is low,

Mis shown on the LCD.

If battery power is below the level required to power the Meter, or

if the sensor fails, the Meter emits a series of five beeps, followed

by a long pause, and another series of five beeps. The Meter

then turns itself off.

If after replacing the battery, the alarm condition persists, the

sensor may have failed. Contact an authorized Fluke service

center for information on how to replace the sensor.

Establishing a Baseline

Before testing for CO, establish a baseline against which the

Meter compares other environments.

Do this by turning on the Meter. If the Meter detects between

0-3 PPM of CO, the beeper sounds and the Meter establishes a

new baseline.

If the Meter detects more than 3 PPM, it does not establish a new

baseline, but starts taking CO measurements.

Storing Maximum Readings (Max/Hold)

In the Max/Hold mode, the Meter stores the maximum CO level it

has detected.

In this mode, the Meter continuously monitors the level of CO,

which is indicated by the beeper, while displaying only the

highest level detected on the LCD.

To enable or disable the Max/Hold mode, press the MAX button;

the beeper emits two quick tones when the Max/Hold mode is

enabled and disabled. When the Max/Hold mode is enabled,

“MAX” is shown on the LCD.

Auto-Back-light

If the ambient light is too low (making the LCD difficult to read),

the LCD back-light automatically turns on. The back-light

automatically turns off when sufficient light is present.

Automatic Power-Off

The Meter automatically turns itself off after 20 minutes.

Muting the Beeper

To mute the beeper, press the ON/OFF switch for more than 2

seconds when turning the instrument on.

The mute beeper icon is shown on the display.

To re-enable the beeper, turn the Meter off and then turn it back

on.

Common Sources of CO

Common sources of potentially dangerous levels of CO are:

•Poorly maintained furnaces, gas heaters, or fireplaces.

•Dirty or plugged chimneys, or flue exhausts.

•Poorly maintained gas, oil, or kerosene appliances.

•Internal combustion engines (e.g., automobiles,

lawnmowers, blowers).
