Page 5: General Information
PM400 Multi-Gas Personal Monitor 1 General Information The innovative new AimSafety PM 4-gas portable monitor brings enhanced convenience and flexibility to gas detection in hazardous environments. The ergonomic PM diffusion gas monitor simultaneously detects up to four gases, including hydrogen sulfide (H S), carbon monoxide (CO), oxygen (O ) and combustibles (LEL). -
Page 6: Difference Between Pmp And Pm Ir
PM400 Multi-Gas Personal Monitor 1.3 Difference Between PM P and PM The PM P and the PM IR are identical units with one exception: The Combustible gas (LEL) sensors are different in each model. The PM P is equipped with a Catalytic Bead (Pellistor) sensor. The PM IR is equipped with a Non-Dispersive Infra-Red (NDIR) sensor. -
Page 7: Non-Dispersive Infra-Red (Ndir) Technology (Pm Ir) Overview
PM400 Multi-Gas Personal Monitor The Catalytic Bead sensor is more prone to sensor drift: These sensors typically require more frequent calibration. The Catalytic sensor requires more power: Due to the sensor design, the Catalytic Bead sensor requires • more power to operate, thus shortening the runtime of the monitor. 1.3.3 Non-Dispersive Infra-Red (NDIR) technology (PM IR) Overview 1.3.3.1... -

Page 13: Menu Screens
PM400 Multi-Gas Personal Monitor WARNING: In the event of an alarm, exit the area and proceed to clean air immediately. 2. Safe Zone Mode enables use as a go/no-go monitor. SAFE ZONE is displayed, unless gas concentrations exceed an alarm setpoint. Should this happen, alarms will activate normally. WARNING: In the event of an alarm, exit the area and proceed to clean air immediately. - Page 14 PM400 Multi-Gas Personal Monitor STEL: Press the [Function key] to advance to the STEL (Short Term Exposure Limit) screen. The STEL screen displays the average level of concentration of each gas for the past 15 minutes. Clear Peaks: Press the [Function key] to advance to Clear Peaks indicated by “CLR” on the display. To clear the peaks, press and hold the [Function key] for three seconds.

Page 18: Bump Test
PM400 Multi-Gas Personal Monitor 5 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. - Page 19 PM400 Multi-Gas Personal Monitor NOTE: Pressing the key too quickly may not advance the display. 5. Press and hold the [Function] key for three seconds to enter the Calibration menu. CAL ZERO displays 6. Press the [Function] key twice to advance to the Bump Test screen. Bump test displays. 7.
- Page 20 PM400 Multi-Gas Personal Monitor Check the calibration gas concentrations, cylinder expiration date, and the monitor gas settings and re-test the unit. If everything looks correct and the unit fails, perform a Zero calibration followed by a Span calibration. Do not use the monitor until the reason for the discrepancy for the test has been determined and corrected.

Page 21: Calibration
PM400 Multi-Gas Personal Monitor 6 Calibration Calibration is the process of adjusting the sensor’s response by using a specific concentration of calibration gas. Sensors will drift for a variety of reasons, so it is important to perform a full calibration periodically to ensure that the sensors response to the target gas are accurate. - Page 22 PM400 Multi-Gas Personal Monitor To perform a Fresh Air Calibration: 1. From the Main screen, press the [Function] to cycle to the Calibration screen. The calibration icon and the Calibration gas settings are displayed. Typical readings clockwise from the upper left are 50, 18.0, 25, and 100.

Page 23: Span Calibration
PM400 Multi-Gas Personal Monitor 6.3 Span Calibration Span calibration adjusts the sensors response to gas to account for sensor drift. It is recommended to perform a Fresh Air calibration prior to a Span calibration. WARNING When performing a Span Calibration only use certified calibration gas at the required concentration level. - Page 24 PM400 Multi-Gas Personal Monitor 5. Press and hold the [Function] key for three seconds to enter the Calibration menu. CAL ZERO displays. 6. Press the [Function] key once to advance to the Span Calibration screen. CAL SPAN displays. 7. Press and hold the [Function] key for five seconds to begin Span calibration. A 90-second countdown timer appears in the lower right corner while the display cycles through detected values of each gas.
