1. Description

The MultiPro is
a multi-sensor
gas detector
that can be
configured to
meet a wide
variety of user
requirements.
This chapter
provides an
overview of many of the features of the
MultiPro. More detailed descriptions of the
specific features of the MultiPro are contained
in the subsequent chapters of this manual.

1.1 Methods of sampling

The MultiPro may be
used in either
diffusion or sample­draw mode. In
either mode, the gas
sample must reach
the sensors for the
instrument to
register a gas
reading. The
sensors are located at the bottom of the
instrument. There are three distinct sensor
ports that allow the sample to reach the
individual sensors.

The sensor ports must be

kept free of obstruction. Blocked sensor
ports can lead to inaccurate and
potentially dangerous readings.

In diffusion mode, the atmosphere being
measured reaches the sensors by diffusing
through the vents at the bottom of the
instrument. Normal air movements are
enough to carry the sample to the sensors.
The sensors react quickly to changes in the
concentrations of the gases being measured.
Diffusion-style operation monitors only the
atmosphere that immediately surrounds the
detector.

The MultiPro can also be used to sample
remote locations with the hand-aspirated
sample-draw kit or with the motorized,
continuous sample draw pump (both available
separately). During remote sampling, the gas
sample is drawn into the sensor compartment
through the probe assembly and a length of
tubing. Remote sampling operations only
monitor the atmosphere at the end of the
sample draw probe.

Use of the hand-aspirated sample draw
kits is covered in section 3.1.

Use of the motorized sample draw pump is
covered in section 3.2.

A detailed description of the MultiPro
probe assembly is given in section 5.7.

1.2 Multi-sensor capability

The MultiPro can be configured to
simultaneously monitor oxygen, carbon
monoxide, hydrogen sulfide and combustible
gases and vapors. All sensors are
replaceable in the field. Each of the MultiPro’s
sensor channels is configured for a specific
type of sensor.

Note: It is necessary to verify the accuracy of
the MultiPro by calibration with known
concentration test gas whenever a change is
made to the sensors installed in the
instrument.

Calibration procedures are discussed in detail
in Chapter 4.

The MultiPro uses electrochemical toxic gas
sensors that have been designed to minimize
the effects of common interfering gases.
These sensors provide accurate, dependable
readings for toxic gases commonly
encountered during confined space entry and
other industrial applications.

Different measurement units are used
depending on the gas being measured.

1.3 Calibration

The MultiPro detector features one-button
fresh air and span calibration.

The accuracy of the
MultiPro should be checked periodically
with known concentration calibration gas.
Failure to check accuracy can lead to
inaccurate and potentially dangerous
readings. (The Canadian Standards
Association (CSA) requires an accuracy
check using known concentration
calibration gas prior to each day’s use.)

8

Calibration procedures are discussed in
detail in Chapter 4.

Recommended calibration frequency is
discussed in Appendix B.

1.4 Alarm logic

MultiPro gas alarms can be adjusted with
BioTrak Software through a PC with an IrDA
port or directly with the MODE button (see
Chapter 6 for direct programming
instructions). Alarms may be set anywhere
within the nominal range of the specific sensor
type. When an alarm set point is exceeded a
loud audible alarm sounds, and the bright red
LED alarm lights flash.

1.4.1 Atmospheric hazard alarms

The combustible gas alarm is activated when
the percent LEL (Lower Explosive Limit) gas
concentration exceeds any pre-set alarm
level.

Two oxygen alarm set points have been
provided; a danger alarm for low
concentrations associated with oxygen
deficiency and a warning alarm for high
concentrations associated with oxygen
enrichment.

Four alarm set points have been provided for
each toxic gas sensor: Warning, Danger,
STEL (Short Term Exposure Limit) and TWA
(Time Weighted Average).

of action is to immediately leave the
affected area, and to return only after
further testing determines that the area is
once again safe for entry. Failure to
immediately leave the area may result in
serious injury or death.

A rapid up-scale reading
followed by a declining or erratic reading
may indicate a hazardous combustible gas
concentration that exceeds the MultiPro’s
zero to 100 percent LEL detection range.

1.4.2 Low battery alarms

The MultiPro may be equipped with either a
rechargeable Lithium Ion (Li-Ion) or an
alkaline battery pack. The MultiPro includes
multi-staged low battery alarms to let the user
know that the battery is running low.

For detailed information concerning the
low battery alarms, see section 2.4.5.

Use only Duracell MN1500
or Ultra MX1500, Eveready Energizer E91­LR6, Eveready EN91 batteries.
Substitution of batteries may impair
intrinsic safety.

1.4.3 Sensor over range alarms.

The MultiPro will go into alarm if a sensor is
exposed to a concentration of gas that
exceeds its established range. In the case of
an LEL reading that exceeds 100% LEL, the
LEL channel will be automatically disabled by
the instrument and the instrument will remain
in constant alarm until it is turned off, brought
to an area that is known to be safe, and then
turned back on. The display will show “OL” in
place of the sensor reading for any channel
that has gone into over range alarm.

See section 2.4.5 for further details on
sensor over range alarms.

A sensor range chart is provided in
Appendix C.

In the event of an LEL
overrange alarm the MultiPro must be
turned off, brought to an area that is
known to be safe and then turned on again
to reset the alarm.

1.4.4 LEL response failure due to lack of

alarm

The MultiPro features automatic warning
against LEL sensor response failure due to
lack of oxygen. See section 2.4.7 for details.

1.4.5 Security beep/flash

The MultiPro includes a security beep function
that is designed to notify the user that the
instrument is powered up and running. Once
enabled the MultiPro will emit a short audible
beep and give a short flash on the LED at a
user-defined interval. The security beep/flash
function may be enabled and the interval may
be changed with BioTrak software or directly
with the MODE button (see Chapter 6 for
direct programming instructions).

1.4.6 Latching peak alarms

The MultiPro’s alarms are self-resetting unless
the alarm latch is enabled. With the MultiPro’s
alarm latch enabled, the audible and visible
alarms will continue to sound after the
atmospheric hazard has cleared. Press the
MODE button to reset the alarms. If the alarm
latch is disabled and the alarm condition is no
longer present, the instrument will
automatically return to normal operation, and
the visible and audible alarms cease without
further input from the user.

1.4.7 Fault detection

MultiPro software includes a number of
additional alarms designed to ensure the
proper operation of the instrument. When the
MultiPro detects that an electronic fault or
failure condition has occurred, the proper
audible and visible alarms are activated and
an explanatory message or message code is
displayed.

The MultiPro is designed to
detect potentially life threatening atmospheric
conditions. Any alarm condition should be
taken seriously. The safest course of action is
to immediately leave the affected area, and
return only after further testing determines that
the area is once again safe for entry.

1.5 Other electronic safeguards

Each time the detector is turned on, the
MultiPro automatically tests the LED alarm
light, audible alarm, internal memory and
pump status (if so equipped). The battery is
monitored continuously for proper voltage.
The MultiPro also monitors the connection of
sensors that are currently installed. The
detection of any electronic faults causes the
activation of the audible and visible alarms
and causes the display of the appropriate
explanatory message.

1.5.1 Heartbeat

At the center of the display is a heart symbol
that will blink every few seconds to show that
the instrument is functioning normally.

1.6 Sensors

The MultiPro can be configured to
simultaneously monitor oxygen, carbon
monoxide, hydrogen sulfide and combustible
gases and vapors. The sensor configuration
of the MultiPro may be specified at the time of
purchase, or changed in the field by
appropriately trained personnel.

Note: A CF Value may be required when
replacing the 54-49-24 CO/H2S sensor.
Instructions are included with the
replacement sensor.

Replacement sensor part numbers and
sensor ranges are given in Appendix B.

Sensor cross-sensitivity figures are given
in Appendix C.

A sensor that cannot be

calibrated or is found to be out of tolerance
must be replaced immediately. An instrument
that fails calibration may not be used until
testing with known concentration test gas
determines that accuracy has been restored,
and the instrument is once again fit for use.

Calibration procedures are discussed in detail
in Chapter 4.

1.7 Optional sample draw pump

A motorized sample-draw pump is available
for the MultiPro for situations requiring
continuous "hands free" remote monitoring.

Use only part number 54­49-102 sample draw pump with the
UL/CSA-approved version of the MultiPro.
Use only part number 54-49-102-5 sample
draw pump with the ATEX-approved
version of the MultiPro.

The pump contains a
pressure sensor that
detects restrictions in
airflow caused by water
or other obstructions
being drawn into the
unit and immediately
acts to turn the pump
off in order to protect
the sensors, pump, and
other MultiPro components from damage.

Pump status is continuously monitored by the
MultiPro microprocessor. When the pump is
