The instrument is equipped with:

− Pneumatic line able to manage up to 2 sensors.

− Easy and immediate user interface so it could be used without the manual support.

− Wide and bright graphic display, White / Black 2” x 2” (50x55 mm).

− Rechargeable 'Li-Ion' battery.

− Supplied with the device is a charging cord with output 5V , 2A to charge the internal batteries. When

needed, it is possible to recharge the instrument battery using a power bank, as long as it is equipped with 5
volts output and 1A minimum current.

Main functions:

- Combustion analysis in manual.

- Comes with the 15 most used fuels (such as natural gas, LPG, gas oil and fuel oil).

- Generation and visualization of a QR code with the purpose of downloading the data of the acquired

measures, having installed the YJ Combustion App which can be downloaded from the AppStore and

PlayStore

4.0 DESCRIPTION OF THE PRODUCT

4.1 Working principle

− The gas sample is taken in through the gas probe, by a diaphragm suction pump inside the CA502.

− The measuring probe has a sliding cone that allows the probe to be inserted in holes with a diameter of 11 mm

to 16 mm and to adjust the immersion depth: it is recommended to have a gas sampling point roughly in
the center of the flue/stack.

− The gas sample is cleaned of moisture and impurities by a condensate trap and filter located in-line in the tubing

for the CA502.

− The gas is then analyzed in its components by an on-board electrochemical cell.

− The electrochemical cell guarantees high precision results in a time interval of up to about 60 minutes during

which the CA502 can be considered very stable.

− When measurements are going to take a long time, we suggest auto-zeroing the CA502 again and flushing the

inside of the pneumatic circuit with clean air.

− During the zero calibrating phase, the instrument aspirates clean air from the environment and detects the cells’

drifts from zero (20.95% for the O2 cell), then compares them with the programmed values and compensates
them.

4.2 Measurement cells

− The instrument takes advantage of pre-calibrated gas sensors for the measurement of Oxygen (O2), Carbon

Monoxide (CO) and optional Nitric Oxide (NO/NOx).

− The sensors do not need particular maintenance, however, they have to be replaced periodically when they

reach their end of life.

− If sensors of toxic gases are used with concentrations higher than 50% of their measurement range for more

than 10 minutes continuously, they can show up to a ±2% drift as well as a longer time to return to zero.

− In this case, before turning off the analyzer, it is advisable to wait for the measured value to be lower than

20ppm by intaking clean air.

− The CA502 is intended to have a cleaning cycle of the pneumatic circuit. The duration of the cycle depends on

what has been set in the menu Configuration→Analysis→Autozero.

− Used O2 sensors can be easily replaced by the user without a complicated calibration procedure with certified

mixtures as they are pre-calibrated before being shipped.

− YELLOW JACKET

4.3 Fuel types

The CA502 device is provided with the technical data of the most common types of fuels stored in its memory.
For more details see Appendix C.Coefficients of the Fuels and Formulas

4.4 Sample treatment

The flue gas suction line has an inline anti-condensation trap with dust filter. The trap and filter condition the gas

sample to be analyzed to be properly dried and cleaned of solid residues of combustion.

4.5 Pressure sensor, piezoelectric, temperature compensated

− The CA502 has a piezoresistive differential pressure sensor which can be used for measuring the draft

(vacuum) in the stack for differential pressure measurement and possibly for other measurements (pressure of
gas in the piping, pressure loss across a filter, etc.).

− The measurement range is –2.95 in hg to 5.9 in hg (-10,000 Pa .. +20,000 Pa.)

− Drift of the sensor is minimized with the autozeroing built into the system.

WARNING
ANY PRESSURE APPLIED TO THE SENSOR GREATER THAN ±8.89inHg (±300 hPa) MAY
CAUSE A PERMANENT DEFORMATION OF THE MEMBRANE, THUS DAMAGING
IRREVERSIBLY THE SENSOR ITSELF.

4.6 Suction pump

The diaphragm pump located inside the instrument, is operated with a DC motor. It is used to obtain the optimal
suction flow rate of the flue gas for the ongoing analysis.

4.7 Draft measurement with sensor automatic autozero

− CA502 performs the draft measurement.

− The sensor autozero allows for zeroing of the sensor and must be done with the gas probe NOT inserted in

the stack.

16.0 MAINTENANCE

16.1 Routine maintenance

This instrument was designed and manufactured using top-quality components. Proper and systematic
maintenance will prevent the onset of malfunctions and will increase instrument life altogether.
The following basic requisites are to be respected:

• When the analysis is over remove the sample probe from the stack and let the analyzer draw fresh air for a

few minutes, or at least until the displayed parameters return to their original values:
O2: >20.0%

Toxic gases: <20ppm

• Clean the filter unit when necessary, replacing the particulate filter and applying a jet of air to the sample

probe hose to eliminate any condensate that may have formed.

Do not clean the instrument with abrasive cleaners, thinners or other similar detergents.
