Non-Dispersive Infra-Red (NDIR) sensor. Be sure to understand the strengths and limitations of the sensor that’s
inside the unit (see below). They directly affect the usage and the lifespan of your detection device.
1.3.1 Over Range Alarm Function
Because of the nature of each sensor, the device will behave differently when exposed to high gas levels which
exceed their sensor ranges this is known as an Over Range Alert.
1.3.1.1 PM
In the event of an Over Range alarm, the Catalytic Bead sensor will prompt Over Range alarms and then turn off the
sensor to avoid damaging the sensor elements.
If an Over Range Alarm sounds, exit to a safe area immediately.
The alarm will continue to sound because the sensor is disabled. To silence the alarm, the monitor will need to be
turned off and back on again, thus re-enabling the sensor.
1.3.1.2 PM
In the event of an Over Range alarm, the NDIR sensor continues to function normally.
If an Over Range Alarm sounds, exit to a safe area immediately.

A simple press of the [Function] key acknowledges and silences the alarm. The sensor continues to stay active even
though the level has exceeded 100% LEL.
1.3.2 Catalytic Bead technology (PM
P) Overview
400
1.3.2.1 Advantages of Catalytic Bead technology
• The Catalytic sensor detects a wide range of combustible (LEL) gasses: The PM
be used if hydrogen and acetylene are among the gases in your environment that require detection.
Make careful note of the disadvantages of this sensor listed below; they have a direct effect on user safety and on
the function of the device.
1.3.2.2 Disadvantages of Catalytic Bead technology
• The Catalytic sensor can be “poisoned”: Certain chemicals will damage the internal elements and cause the
sensor to lose sensitivity. Common poisons are chemicals which contain silicon (found in hand lotions and
industrial lubricants) and Sulfur compounds, which can be released with gases. Chlorine (found in many
cleaning products) and heavy metals can also poison a catalytic sensor. This list is by no means
comprehensive.
• The Catalytic Bead sensors require oxygen to detect gases: Because a Catalytic Bead sensor burns the
sample of gas, oxygen is required for the monitor to detect the presence of combustible gases.
• The Catalytic Bead sensor can burn out: Exposure to high concentrations of gas can completely disable the
sensor. See section 1.3.1 Over Range Alarm Function.
P is the device that should
400
REV – 2.0 [34-2900-0206-2 ] 5 | Page

PM400 Multi-Gas Personal Monitor
The Catalytic Bead sensor is more prone to sensor drift: These sensors typically require more frequent calibration.
See
• 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
1.3.3.1 Disadvantages of NDIR technology
• Doesn’t detect certain combustible (LEL) gasses: Gases such as hydrogen and acetylene go undetected by
NDIR sensors.
Be sure the safety of your users isn’t dependent on detecting hydrogen and/or acetylene. The PM
detect these gases.
1.3.3.2 Advantages of NDIR technology
• The NDIR sensor does not require oxygen to detect gases: Because the NDIR sensor uses absorbed light
spectrum technology to detect combustible gases, the sensor does not require oxygen to operate, making it
ideal for inert and oxygen deficiency applications.
• The NDIR is more durable: Cannot be inhibited, poisoned by external chemicals and gases.
• The NDIR sensor is more stable: Requires minimal recalibration and is typically stable even after extended
storage.
• The NDIR sensor has a longer lifespan: The sensor has a life expectancy of up to 10 years.
• The NDIR sensor requires less power: Due to the sensor design the NDIR sensor requires less power to
operate, thus allowing for extended runtimes compared to the Catalytic Bead sensor.

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.
To perform a Bump Test:
1. On the Measuring screen, make sure the oxygen sensor reads 20.9 and the other gases read zero.
2. Clip the calibration cap to the unit. The cap attaches to the recesses in either side of the unit. You should
hear a click when the cap is secure.
NOTE: Be sure that the word “Calibration” is right-side-up.

3. Ensure that the regulator is firmly attached to the gas bottle and that the hose is securely attached to the
regulator and to the calibration cap.
NOTE: Do not turn on the gas at this time.
4. From the Main screen, press the [Function] key to advance 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.

6. Press the [Function] key twice to advance to the Bump Test screen. Bump test displays.
7. Press and hold the [Function] key for three seconds to initiate the bump test. GAS NO and a 45-second
countdown timer are displayed.
8. Turn on the gas regulator. A new 45-second countdown timer appears in the lower-right corner while the
rest of the display alternates between GAS IN and real-time gas measurements.
9. Watch the display as the timer counts down. Results should appear within roughly 20 seconds. If the test is
successful, OK appears in all four corners of the display.
10. Turn off the gas regulator, disconnect the calibration cap, and wait for the gas to dissipate.
11. Clear peaks before proceeding. See Clear Peaks in Section 4.5 Menu Screens for instructions.
If the test fails, the gas(es)/sensor(s) that failed are displayed. This failed bump test message continues to flash on
the display until a successful bump test or calibration is performed.

If the Bump Test fails, do not use the monitor until a successful Bump Test or Calibration
is performed.
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.

received, calibration should be performed monthly (or quarterly) depending on
frequency of use.

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. A full calibration consists of two points, a Fresh Air Calibration
and a Span Calibration.
Fresh Air Calibration adjusts the zero offset of the toxic and LEL sensors or sets the oxygen sensor to 20.9% Vol.
