Common Sources of CO
Common sources of potentially dangerous levels of CO are:
• Poorly maintained furnaces, gas heaters, or replaces.
• Dirty or plugged chimneys, or ue exhausts.
• Poorly maintained gas, oil, or kerosene appliances.
• Internal combustion engines (e.g., automobiles, lawnmowers, blowers).
CO and Appliance Malfunctions
The following table identies typical problems that can produce high levels
of CO.

CARBON MONOXIDE METER
INSTRUCTION SHEET
INTRODUCTION
The Carbon Monoxide 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 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.
What the Meter Does
The Meter indicates the presence of CO by a reading the LCD and by beeper
tone.
The beeper function is much like clicking a Geiger counter:
• Above 200 PPM, the beeper sounds continuously with the concentration of CO.
• From 35 PPM to 200 PPM, the beeper sounds discontinuously with the
concentration of CO.

3. MAX Hold button
4. Data Hold button
5. Back-light button
6. Power button
7. Battery door
DATA HOLD
The Data Hold function allows the meter to "freeze" a measurement for later
reference.
1. Press the DATA HOLD button to "freeze" the reading on the indicator.
The indicator "HOLD" will appear in the display.
2. Press the DATA HOLD button to return to normal operation.
MAX HOLD
To hold the highest reading on the LCD, press the MAX hold button. The MAX
hold button is located on the left side of the meter (bottom button). The
meter reading will not change as readings change, rather it will only display
the highest reading encountered since the MAX hold button was pressed.
Press the MAX hold button again to return to normal operation.
BACKLIGHT BUTTON
1. Press the "BACKLIGHT" key, the "light" will appear in the display.
2. Press it again and the "light" will close.
POWER BUTTON
1. Press the power button to turn on
2. Press the power button again to turn off
BATTERY REPLACEMENT
1. If battery power is not sufficient, LCD will display “ ” replacement with
one battery type 9V is required.
2. Open battery cover, then take out the battery and replace with a new 9-Volt
battery and put back the battery cover
