WARNING
Any unauthorized attempt to repair or modify the product, or any other cause of damage beyond the range
of the intended use, including damage by fire, lightening, or other hazard, voids liability of the manufacturer.
Only activate this product only if sensor, visual, detection, and audible cover are clear from contaminants such
as dirt and debris that could block the area where gas is to be detected.
Do not clean and rub the LCD screen of the products with a dry cloth or hands in hazardous environment to
prevent static electricity buildup.
If the CO2 concentration reaches 0 ppm, a calibration should be performed.
CAUTIONS
Before operating this device, please read and understand this manual.
This device is not an analyzer, but a gas detector.
Do not use the device if calibration and self-test continuously fail.
Clean device with a soft cloth. Do not use chemical substances for cleaning.
View a serial number on the label at the back side of the device. (ex. 2021.01.01)

1General Information
The PM150-CO₂ is a portable single gas detector designed to detect the presence of carbon dioxide gas in ambient
environment. When activated, PM150-CO₂ continuously monitors ambient air for the presence of carbon dioxide gas
and alerts the user to potentially unsafe exposure with LED, vibrating, and audible alarms if gas concentration exceeds
alarm set points. The settings value can be adjusted manually or by connecting to the PC software.

4Activation
4.1 Activating the PM150-CO2
Move the monitor to a fresh air environment, which is free of hazardous gas. Press and hold down the power button for
approximately two (2) seconds until the gas type (CO2) is displayed. Upon activation, gas type (CO2), firmware version, and
display appears, and thedetector performs the self-diagnostic test for 10 seconds. After self-test is successful, the detector
countdown is displayed for 10 seconds. Allow the detector to stabilize for 90 seconds until warm up message (---) is no
longerdisplayed. The detector will then display the current CO2concentration.
4.2 Error Messages
If stabilization has failed, Error mark is displayed and measuring mode will not be entered. In this case,contact
AimSafety for repair or return.

4.3 Bump Test
A bump test is used to test that the monitor is working properly. During a bump test, a known concentration of gas is
applied to the sensor to verify that the sensor responds to the gas, and the alarms activate. This is the only way to
effectively confirm that all characteristics of the monitor and the sensor are working correctly.
WARNING
A bump test should be conducted before each day’s use.
Ensure that you are in a clean environment before performing a Bump Test.
The monitor must be calibrated if it fails a Bump Test.
To perform the bump test:
•Prepare a gas cylinder with a CO2 concentration that exceeds the low and high alarm set points.
•Press and hold the Function key and power button for three seconds in the measurementmode. Press the Function
key until “TEST” is displayed and press the power button two (2) seconds to enter the mode.
•Press the Function key until “BTS is displayed and press the power button to activate it.
•After pressing the power button, apply a CO2gas over low and first alarm and the 30 seconds count down is
displayed.
•Once the test has passed, “SUC” (V) icon appears on the display. If test is failed, “FA” (X) mark appears on the display.

flash (LED), and beep. To remove alarms, move to a clean air location. When a gas concentration is decreased
below the alarm set points, alarm will stop.
Low Alarm
• Audible Alarm: Three (3) beeps per seconds
• LED: Three (3) flashes per seconds
• Vibration: One (1) vibration per second
High Alarm
• Audible Alarm: Four (4) beeps per seconds
• LED: Four (4) flashes per seconds
• Vibration: One (1) vibration per second
STEL & TWA Alarm
• Audible Alarm: Four (4) beeps per seconds
• LED: Four (4) flashes per seconds
• Vibration: One (1) vibration per second
6.2 Adjust alarm set points
• To enter the setting mode, press and hold the Function key and power button simultaneously
for two seconds.
• In the alarm setting icon, press and hold down the power button for two (2) seconds.
- Press the Function key to change the alarm set points.
- Press the power button to save the value and move to
the next step.
CAUTION
Ensure that the high alarm setpoint must be greater than low alarm setpoint. Alarm setpoints may vary by
a country, states, and company policy. Unless specified in your company’s safety instruction, use the preset
alarm setpoints. Before the alarm adjustment, check with your safety manager or authorized dealer.
Ensure Standard Factory alarm set points vary depending on countries, states, and companies.
Before changing alarm setpoints, ensure the alarm set points follow your local guidelines.
For safety, users are not allowed to set the 1st alarm value to zero. When attempting to set 1st alarm to zero,
the value will change to 400 ppm.
6.3 Data Log
The detector stores the last 30 event logs. If the data is filled, the new log event overwrites the oldest log events.
The data log is stored at one (1) minute intervals, and it stores about 64,000 data logs.
Data logs consisting of event log, bump, and calibrations are stored at one (1) minute intervals.
To transfer event logs and data log to a computer:
•Install the current AimSafety CO2USB link software found at www.macurco.com/downloads
•Connect the detector to a computer via the supplied USB-C cable.

8Calibration
CAUTION
Initial calibration is performed on all devices prior to shipment.
The detector has the zero calibration (N2) and span calibration (CO2)
The frequency of calibration depends on the use case. More frequent calibrations may be required
depending on the frequency of use and personal risk. For instance, if you use the device daily, weekly or
monthly calibration may need to be performed, while the device is used a few times a year, monthly or
quarterly calibration may be required. Before calibration, check with your safety managers to ensure
calibration accessibility.
If calibration fails, attempt to perform a re-calibration. If the calibration continues to fail, contact an
authorized distributor or AimSafety.
8.1 Calibration Gas Values
Gas Type Zero (N₂) Span (CO₂)
Concentration 99.99% Vol 20,000 ppm, 2% Vol
8.2 Zero (N2) Calibration
1. Assemble the calibration equipment with zero gas cylinder. See
Figure 8-1
2. In the “CAL” mode, press the Function key to move to the “ZErO”
calibration.
3. Attach the calibration cap to the detector.
4. Press and hold the power button for three (3) seconds to start the zero
calibration. Once the countdown timer has started, open the valve on the
regulator to start the flow of gas.
5. After 90 seconds, when the zero calibration is successful, success
message (V) appears. If the zero calibration fails, FAIL message (X)
appears.
Note: Press the power button during the 90 second countdown to abort the zero calibration.
CAUTION
Use the regulator with a flow rate of 0.2 LPM (Liters per minute).

2. In the “CAL” mode, press the Function key to move to the “SPAn” calibration.
3. Attach the calibration cap to the detector.
4. Press and hold the power button for three (3) seconds to start the span calibration. Once the countdown timer
has started, open the valve on the regulator to start the flow of gas.
5. After 90 seconds, when the span calibration is successful, success message (V) appears.
If span calibration fails, fail message (X) appears.
Note: Press the power button during the 90 second countdown to abort the span calibration.
CAUTION
