Frequently Asked Questions - CO-220 FLUKE

What is the Fluke CO-220 used for?

The Fluke CO-220 is a portable carbon monoxide gas detector used to measure CO levels in the air, providing audible and visual alarms when dangerous concentrations are detected.

How do I change the batteries?

To replace batteries, open the battery compartment on the back of the unit, remove and recycle old batteries, then insert two new AA alkaline batteries observing polarity. Close the compartment securely.

What does the alarm mean?

The alarm activates when CO concentration exceeds the adjustable threshold (default 35 ppm). It sounds a loud tone and flashes a red LED. Evacuate the area and ventilate immediately.

How often should I calibrate the CO-220?

Fluke recommends annual calibration to maintain accuracy. Calibration can be performed using a known CO gas standard and the zero/span adjustment procedures.

Can I use the CO-220 in extreme temperatures?

The operating temperature range is 0°C to 50°C (32°F to 122°F). Avoid exposure to temperatures outside this range; store between -20°C and 60°C.

Why does the display show 'Err'?

An 'Err' message may indicate a sensor fault or calibration error. Try resetting the unit by removing and reinserting batteries. If the error persists, contact Fluke service.

Does the CO-220 detect other gases?

No, it is designed specifically for carbon monoxide (CO) detection using an electrochemical sensor. It is not suitable for detecting combustible gases or other toxic gases.

How long does the battery last?

With fresh alkaline batteries, the CO-220 provides up to 300 hours of continuous operation. Low battery indicator alerts you when replacement is needed.

What is the resolution and accuracy?

Resolution is 1 ppm. Accuracy is ±5% of reading or ±5 ppm (whichever is greater) at 25°C, with additional temperature effects.

How do I reset the alarm threshold?

To adjust the alarm setpoint, press and hold the MODE button until the setpoint flashes, then use the UP/DOWN buttons to set between 0 and 1000 ppm. Press MODE to confirm.

CO-220

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.

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,

+ is 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.
