一氧化碳分析儀CO-180英文說明書
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 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.
0-1PPM | 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.
The beeper functions much like clicking of 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.

Instrument Familiarization:
- CO sensor
- LCD Display
- MAX Hold button
- Data Hold button
- Back-light button
- Power button
- Battery door
DATA HOLD
The Data Hold function allows the meter to “freeze" a measurement for later reference.
- Press the DATA HOLD button to “freeze" the reading on the indicator.
The indicator “HOLD" will be appear in the display.
- 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
- Press the “BACKLIGHT" key, the “light" will be appear in the display.
- Press it again, the “light" close.
POWER BUTTON
- Press the power button, power is on and the meter can measure.
- Pull it again, Power is off.
BATTERY REPLACEME
As battery power is not sufficient, LCD will display “ " replacement with one battery type 9V is required.- Open battery cover, then take out the battery from instrument and replace with a new 9-Volt battery and place the battery cover back.
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., autos, lawnmowers, blowers).
CO and Appliance Malfunctions
The following table identifies typical problems that can produce high levels of CO.
Appliance | Fuel | Typical Problems |
Gas furnaces Room heaters | Oil, natural gas, or LPG (liquefied petroleum gas) | 1. Cracked heat exchanger. 2. Not enough air to burn fuel properly. 3. Defective/blocked flue. 4. Maladjusted burner. 5. Building not properly pressurized. |
Central heating furnaces | Coal or kerosene | 1. Cracked heat exchanger. 2. Not enough air to burn fuel properly. 3. Defective grate. |
Room heaters Central heaters | Kerosene | 1. Improper adjustment. 2. Wrong fuel (not K-1). 3. Wrong wick or wick height. 4. Not enough air to burn fuel. 5. System not properly vented. |
Water heaters | Natural gas or LPG | 1. Not enough air to burn fuel properly. 2. Defective/blocked flue. 3. Maladjusted burner. 4. Building not properly pressurized. |
Ranges Ovens | Natural gas or LPG | 1. Not enough air to burn fuel. 2. Maladjusted burner. 3. Misuse as a room heater. 4. System not properly vented. |
Stoves Fireplaces | Gas, wood, coal | 1. Not enough air to burn fuel properly. 2. Defective/blocked flue. 3. Green or treated wood. 4. Cracked heat exchanger. 5. Cracked firebox. |
CO-180一氧化碳檢測儀可探測一氧化碳的存在和檢測百萬分之1-1000(PPM)之間的一氧化碳濃度。
此表通過兩種途徑表明一氧化碳的存在：
·通過液晶顯示屏上顯示PPM讀數
·通過蜂鳴提示
特征
1.取樣速度快
2.zui大值保持
3.數據保持功能
4.自動關機功能
5.一氧化碳濃度在200 PPM以上時，蜂鳴聲連續響
此檢測儀通過LCD上顯示讀數和蜂鳴聲來提示CO的存在。蜂鳴聲：
·一氧化碳濃度在200 PPM以上時，蜂鳴聲連續響。
·一氧化碳濃度在35 PPM 到 200 PPM之間時，蜂鳴聲間續響
