WELCOME
Thank you for purchasing our YES Plus LGA multi-sensor, air quality monitor and
information recording instrument. The YES Plus LGA series of instruments are easy to
use, portable, monitoring and information recording devices for monitoring trends that
pertain to indoor air quality.
The YES Plus LGA is equipped with rear mounted temperature and relative humidity
sensors to aid in verifying readings providing a comprehensive indication of air quality.
Information readings are written to a plug-in SD flash card providing bullet-proof memory
to protect your recorded information. The sample rate can be adjusted using the supplied
software or through the instrument menu. The instrument may be hand-held or will easily
stand on a flat surface.
The YES Plus LGA series of instruments are manufactured with plug-and-play,
interchangeable sensor modules to allow for multiple gas testing. The specifications listed
in this manual indicate a wide array of sensors to choose from. These sensors may be
changed in the field and operated within minutes (accurate readings will require more
time as each sensor type has different warm up / stabilization periods before they are
able to perform to published specifications).
Calibration and repair is available at our manufacturing facility and through some of our
authorized and trained distributors.
The YES Plus LGA can reliably record time-based information, which can be downloaded
via the USB port located on the rear of the instrument or for faster downloading through
the use of a USB card reader. Any computer capable of running Microsoft Windows 2000
or higher (with an available USB communications port) can accommodate the YES VIEWER terminal software.
If after reading through the manual, you have any questions, please do not hesitate to
contact our service department for technical support.

NOTE-1: Not all of the above sensors are available from stock. Delivery time for sensors
ordered will vary depending on which sensors are ordered, how many are ordered and
measurement range desired.
NOTE-2: Other measurement ranges are available for some sensors. Contact factory
with desired range to confirm availability.
NOTE-3: Some of the these sensors must be calibrated with correlation gases because
they are more readily available. If the customer wishes them to be calibrated with the
exact target gas, extra charges will apply to acquire the specific gas if and when
available. In these cases, customer will be required to take delivery of the special cylinder
of span gas and dangerous goods and shipping costs will apply.

NOTE-4: Some of the above sensors have cross sensitivities to other gases (interfering
gases). Please refer to the sensor specification chart before ordering a specific sensor if
your application may have some of the interfering gases present.
NOTE-5: All sensors have an identifiable life span and must be replaced at the end of
their usable life. Reference the following sections for more information: pages 28-30,
section 7.0 and page-26, section-6.
2.1 SENSOR CONFIGURATION NOTES, IMPORTANT
It is important to note that although the YES Plus LGA will accommodate fifteen sensors
and twelve (12) of those sensor locations are plug and play, there are sensor placement
considerations.
Of the twelve plug and play sensor locations, eight are for electrochemical sensors. If the
user selects an Oxygen (O2) sensor or any other 2-electrode electrochemical sensor, it
must be fitted to either sensor location 7 or 8. If the user selects a Nitric Oxide (NO) or
any other sensor requiring electronic bias within the circuit, it must be fitted to sensor
location 5 or 6. Sensor locations 1 to 8 can accommodate any other standard 3-electrode
electrochemical sensor. Sensor locations 9 to 12 accommodate infrared, PID or catalytic
sensors. Reference the photo drawing on page-32 for specific sensor locations.

range of features and functionality. All features and functions can be set to meet the user’s specific requirements.
BUTTON PRESSING: The four tactile push-buttons on the front face of the instrument
should be pressed firmly and slowly. They have been designed such that an accidental
light touch does not register and change something the user may be working on.
SECURITY CODE: Some functions within the menu system are protected by a security
code to prevent unauthorized or untrained personnel from accessing them and changing
critical values within the instrument that might produce incorrect or unsafe readings. All
YESAIR instruments are shipped from the factory with a generic security code of “1, 2, 3,
4”. It is recommended the user change this to a code known only to authorized personnel.
4.1 SWITCHING INSTRUMENT ON / OFF
IMPORTANT NOTE: WHEN USING PUSH-BUTTONS ON FRONT OF INSTRUMENT
ENCLOSURE, PRESS FIRMLY AND WATCH THE DISPLAY FOR MOVEMENT. A
LIGHT FINGER PRESS WILL NOT ENGAGE THE DOMED CONTACT. THIS IS TO
PREVENT ACCIDENTAL CHANGES TO MENU.
SWITCH ON: Press “ ON/OFF” button down momentarily then release. The LCD will
indicate “YES+LGA PORTABLE AIR QUALITY MONITOR”, FIRMWARE VERSION,
CURRENT DATE, CURRENT TIME, and finally “ WARMING UP UNIT, PLEASE
WAIT…”. At the bottom of the display, a bar will fill in and indicate the percentage
of warm-up completion to the right. A battery symbol will be indicated on the bottom right
side of the display if the instrument is being operated from battery power.
After warm-up is completed, the display will automatically display the sensor type, real
time reading and unit of measure for the first six sensors. If more than six sensors are
installed, the display will automatically scroll to another page and display the balance of
the installed sensor types, real time readings and unit of measure.
SWITCH OFF: Hold “ ON/OFF” button down for four to six seconds then release.
The multi-line LCD will indicate “Shutting monitor off”.
NOTE-1: More accurate real-time readings will occur after the sensors have warmed up
and stabilized a little longer.
NOTE-2: Warm-up can be skipped by holding the MENU button for 3-5 seconds
There are three more tactile push-buttons on the front panel of the instrument. “Arrow up”,
“Menu” and “Arrow Down”. These buttons are used to access the instrument menu
system for programming purposes.
IMPORTANT NOTE: Upon switching the YES Plus LGA on, the user will hear a low,
steady buzzing tone. This is the sound of the new, powerful internal sample pump. The
sound has been dampened internally but the sound of the pump will always be audible to
a certain extent.

4.0 INSTRUMENT OPERATION
4.3 MAIN MENU FUNCTIONS, CONT’D…..
DATALOG: This menu item allows the user to set up the internal data logger to suit their
specific application. This function can also be achieved with the instrument connected to
a computer. Set up and programming through a pc is faster but the YES Plus LGA data
logging function can be completely set up through the menu in the instrument.
ALARM: This menu item allows the user to set the alarm levels as well as which alarms
are activated.
INFO: Provides the user with information on the instrument such as serial number
assigned and date of manufacture. It also provides the user with information on the
installed sensors such as sensor serial number, date code, and calibration date
information.
USB: Allows the user to reset the USB chip if the YES Plus LGA will not communicate
with YES Viewer software.
5.0 MENU FUNCTION DETAILS
CALIBRATE: Pressing the MENU button at this menu function puts the user into the
calibration section of the menu. The LCD immediately indicates “ENTER SECURITY
CODE” . The user must input a 4-digit security code to access the calibration menu. This
prevents unauthorized users from tampering with the calibration settings. All YES Plus
LGA instruments are shipped from the factory with a generic security code setting of
“1234”. The user can easily change this code setting for extra security. Reference page22 of this manual.
NOTE: If the wrong security code has been entered, the display indicates “INVALID
SECURITY CODE ENTERED” and the display flips back to the menu list.
The calibration menu provides the user with two main functions to calibrate all sensors,
SPAN and ZERO. Both of these functions are required as part of the regular instrument
maintenance to achieve “best performance” from the sensors. Zero function must be
performed before the span function.
PID sensors for TVOCs (Total Volatile Organic Compounds) should be calibrated every
three months for best performance if being used in dirty or semi-dirty environments. This
sensor measures the “total” response from all VOCs in the target area and cannot identify
individual gases or chemicals.
NOTE: When calibrating the PID sensor, make sure that the display unit reading is in
PPM. If not, change the unit to PPM (refer to Section 5.0 page 21 “VOC”). After calibration you may change the unit ug / m³.
Infrared CO2 sensors should be calibrated yearly for best performance.
Electrochemical, toxic gas sensors should be calibrated every six months for best
performance.
Catalytic, combustible gas sensors should be calibrated every six months for best
performance.
19
5.0 MENU FUNCTION DETAILS
CALIBRATE, CONT’D…..
Both zero and span functions are automated. Before span adjusting the sensor, the user
must first tell the YES Plus LGA what concentration of span gas is being used to span
each sensor. This does not apply to temperature, RH or Oxygen sensors. Temperature
and RH sensors must be calibrated using a controlled environment such as a chamber.
With Oxygen sensors, it is assumed you will use the environment around you because it
contains approximately 20.9% O2. After that, push the menu button over the zero or span
selection and follow the instructions on the LCD.
NOTE: For more information on calibration function, see calibration section 6.0,
page 27 of this manual.
CALIBRATION FREQUENCY: The frequency of calibration maintenance to expect
best performance from installed sensors. Temperature and Relative humidity sensors
should be calibrated once per year. Reference bottom of page-21 for details on other
sensor types.
SETTINGS: This menu item provides the user with the ability to configure much of
the instrument functionality to suit their specific needs. Use the ARROW DOWN button to
scroll to “SETTINGS” then push the MENU button to enter this menu and view the listed
functions. Use the ARROW DOWN button to scroll to the function you wish to change and
press the MENU button.

6.0 CALIBRATION PROCEDURE
This section details the calibration procedure and is an extension of the description from
pages 19 to 21 of this manual.
NOTE: Calibration should always be performed by a trained and experienced technician. Temperature and Relative Humidity sensors must be calibrated using a special
chamber and therefore field calibration is not permitted. Only gas sensors can be field
calibrated.
Equipment Required & Cautions:
1) Always ensure batteries are fully charged before starting calibration procedure. This is
especially important when calibrating sensors that are more “current hungry” such as
infrared, combustible and PID for TVOCs.
2) Allow a twenty (20) minute warm up period before attempting calibration of any gas
sensors. This allows all sensors time to fully warm up and stabilize and produces the
most accurate results for calibration.
3) Always perform both zero (null) and span functions on all sensors. Zero function
involves flowing 100% Nitrogen into the inlet port of the instrument.
4) Cylinders of Nitrogen and appropriate span gases are required for calibration. Ensure
the cylinder regulator has a minimum flow rate of approximately 0.7 LPM to a maximum of
1.0 LPM. The pump inside the YES Plus LGA must not be “drawn down” because of a low
flow rate from a cylinder regulator. The result will be inaccurate calibration values. Span
gas values should preferably be approximately 40% to 60% of the installed sensor
measurement ranges. Always remove cylinder regulators from air and gas cylinders
before storing.
Calibration can be achieved from the instrument keypad menu or through the pc
information gathering (data logging) software. The following procedure deals only with
calibration procedure through the instrument keypad menu. The procedure to achieve
calibration from the pc software can be found in the separate software manual.
PROCEDURE:
ZERO:
Press the MENU button on the instrument to enter the main menu. Using the ARROW
DOWN button scroll down to “ CALIBRATE” and press the MENU button. The LCD
will indicate “(CODE) ENTER SECURITY CODE” . The calibration function is security
code protected to prevent unauthorized personnel or personnel that have not been
trained, from performing this important function.
Enter the security code correctly and the LCD indicates “CAL” and the next menu
selections “PREVIOUS”, “SPAN” “ZERO”.

NOTE-1: If the user neglects to flow 100% Nitrogen over CO2 and O2 sensors or
zero air over all other sensors, the instrument indicates an error.
NOTE-2: The O2 sensor does not indicate the first span menu screen (APPLY GAS
NOW). For this reason, ensure any Oxygen span gas utilized is connected and
flowing to the sensor before entering the span menu. Alternatively, use the ambient environment as a source of 20.9% volume O2 but make sure you do not exhale in the direction of the pump inlet fitting. The CO2 you exhale will influence the value of the Oxygen
reading. It is the only sensor that skips the first span calibration menu screen.
7.0 ADDING OR CHANGING PLUG-AND-PLAY SENSORS
The YES Plus LGA accommodates up to fifteen sensors. One of those sensors is
temperature and is permanently installed in all instruments as a standard. Twelve of the
sensor locations accommodate only gas sensors. Eight of the sensor locations
accommodate only electrochemical toxic gas and/or Oxygen sensors. The other sensor
locations can accommodate either the infrared CO2 sensor, the PID sensor or the
catalytic combustible (flammable) gas sensor. See photo reference on page-16.
Although a RH (relative humidity) sensor is an option, it must be installed at the factory at
the time of assembling the instrument and as such must be ordered at the time of
ordering the instrument.

7.0 ADDING OR CHANGING PLUG-AND-PLAY SENSORS, CONT’D…..
SENSORS, CONT’D…..
All YES Plus LGA gas sensors are plug-and-play smart sensors. They can be added or
changed at any time. The procedure to add or change a sensor is as follows:
1) Shut the instrument off. If the power adapter is plugged in, UNPLUG IT BEFORE
PROCEDING. “WARNING” LEAVING AC ADAPTER PLUGGED IN WHILE CHANGING
SENSORS CAN SERIOUSLY DAMAGE SENSORS. THIS DAMAGE WILL NOT BE
COVERED UNDER WARRANTY.
2) Rotate the swivel carrying handle to the front resting position. Turn the instrument over
and loosen the four 1-1/2” long securing screws located on the bottom of the instrument.
Turn the instrument right side up again and carefully remove the cover. The swivel handle
is attached to the cover and will come off with it.
3) Gently slide the front panel with LCD display up and out of it’s slot and stand it in front
of the instrument. This ensures the display ribbon cable is out of the way for the sensor
block removal. Remove the four securing screws retaining the sensor block and carefully
lift it off, laying it to one side on top of the circuit board. If one or more sensors adhere to
the sensor block while removing it, carefully remove them and plug them back into their
locations. If they fall from the underside of the cover while removing it, they become damaged.
4) If you are removing a sensor, identify the one to be removed by the label on the side of
the sensor then carefully grasp the sensor by the sides and pull upwards with a slight
rocking motion to unplug it from the sensor sockets in the transmitter circuit board. DO
NOT DROP the sensor (permanent damage could occur). The removed sensor should be
stored in a clean, dry container with anti-static foam.
5) If another sensor is to be installed in it’s place, ensure it is of the same
“type” (electrochemical, infrared, PID/Catalytic), to be accommodated by the sensor
location recently vacated. Carefully grasp the new sensor by the sides and line up all of
the pins on the smart sensor board attached to the bottom of the sensor with the sockets
on the transmitter board. Once the pins are all aligned, gently push the sensor down into
the sockets in the transmitter circuit board. If it does not seem to be easy to insert the new
sensor, DO NOT FORCE it. Double check the pin to socket alignment and try again.
NOTE: If no sensor is to be utilized in a specific sensor location, the opening must
be filled with a sensor blanking plug to allow sampled air to reach all sensor locations.
6) Reattach the sensor block and tighten the securing screw until it will reach to the housing then do another three full turns (DO NOT OVER TIGHTEN). Carefully slide the front
panel back into it’s slot in the enclosure base. Carefully slide the cover into position ensuring that the front and rear plates align with the slots in the cover. Install the four 1-1/2”
long securing screws and tighten. DO NOT OVER TIGHTEN.
7) Switch the instrument on and allow at least 20 to 30 minutes of warm up time before
using.
31
7.0 ADDING OR CHANGING PLUG-AND-PLAY SENSORS, CONT’D…..
8) Once the sensor has been warmed / stabilized, perform a zero function using the
pushbuttons on the front of the instrument. This function is part of the calibration
procedure indicated on page-27. This can be performed in room air if you know the air in
the environment is clean. If the sensor is CO2 or O2, 100% Nitrogen (N2) must be flowed
over the sensor as part of the zero function.
NOTE-1: If the newly installed sensor is not zero adjusted after installation, as outlined above, the display may indicate a slight reading of the target gas even in a clean
environment.
NOTE-2: For best accuracy, all sensors should be zero adjusted and bump tested
after being installed.

Sensor locations 1 to 8 accommodate the 3-electrode style electrochemical sensors.
Locations 5 and 6 will also accommodate electrochemical sensors that require a bias
voltage. Locations 7 and 8 will accommodate the typical 3-electrode sensor, and also
2-electrode style electrochemical sensors. (This is typically an oxygen sensor, but some
rare gases also fall into this category.)
Positions 9 through 12 accommodate the 3-pin infrared (IR), catalytic or PID sensors.
These sensors have a higher power draw and as a result, the pins have been spaced
differently to ensure they are not accidentally placed in locations 1 to 8. Doing so could
potentially damage the electronics of the instrument.
8.0 INFORMATION RECORDING (DATA LOGGING) OPERATION
Refer to the YES VIEWER SOFTWARE MANUAL for complete details on loading
and using the YES Viewer software.

9.0 MAINTENANCE
Externally, the YES Plus LGA requires only cleaning with a damp cloth, wiping off the
exterior surface and basic inspection for obvious damage or problems. Internally, sensors
should be maintained because they have a specific life span. As they age, they must be
calibrated (null and span adjusted) for accuracy. If one or more sensors do not respond to
span gas, check the age of the sensor as they may have expired. Refer to the sensor
replacement and calibration sections of this manual for more details. Contact the factory
for service to replace expired sensors or any other parts that are required.
10.0 ACCESSORIES (optional, not included with standard package)
1) Hand-held probe.
The Hand-held Probe has 30” of hose and allows the user to attach a sample probe
(wand) to reach into hard to get at areas for sampling.
NOTE: For remote sampling of gases only. Temperature and RH sensors are mounted
on the rear panel of instrument.
2) Hard shell, foam-lined, durable carrying / transport case.
