Introduction

The C-Squared CO Analyzer is designed to measure CO levels in the 1ppm to 100ppm range.
It can be used to measure the CO content to assure safety in gas mixes that may be
contaminated due to the introduction of CO from internal combustion engines or other pumping
devices where CO is a bi-product. The Analyzer is designed to be able to verify CO
concentration in cylinders as well as analyze closed spaces.

The C-Squared Analyzer has a digital display, an internally or externally mounted temperature
compensated sensor with a 1 year life expectancy. The power is supplied by three AAA 1.5
volt batteries providing an expected operation life of one year before replacement is required.

The case has an environmentally sealed, potentiometer, on/off switch, long life sensor and
digital panel meter. The Analyzer is water resistant and sealed to prevent moisture from
affecting the internal components.

The Analyzer is shipped in a high impact case that can be used for storage or other purposes.
The Analyzer is ready to use out of the box with no additional work other than checking on the
calibration with an appropriate calibration gas at 50 or 100ppm.

Controls

The C-Squared Carbon Monoxide Analyzer has a splash proof on/off switch. When the switch
is centered it is in the off position. When not in use, the switch should be in the off position to
conserve battery life. When the switch is in the up position it is on. When the switch is flipped
down the unit will remain in the off position.

When switched on, the analyzer’s display will indicate a CO reading. Please note that the
analyzer has been calibrated prior to shipping but it should be checked routinely (see
calibration section).

The low battery warning is a battery symbol in the left corner of the display. When present
change the batteries prior to using the analyzer.

The display has a 1 ppm resolution and is sealed.

Gas Calibration:

Calibration is desirable prior to every use. For gas mixtures or room monitoring you should
use a CO calibration of 50ppm or 100ppm concentration before use. This assures minimum
deviation and greatest accuracy. The CO Analyzer is factory calibrated and marked for 93
ppm CO with calibration gas. As the sensor ages it would be correct to either send the unit
back for recalibration or reset the calibration using the above concentrations of certified gas.
For regular use expose the analyzer to the calibration gas and adjust the calibration knob until
the display reads the listed concentration of the Calibration gas.

The analyzer is now ready for CO measurement.

WARNING:
The analyzer is sensitive to partial pressure. Calibration must always be carried out at
the same pressure as the CO measurement.

Carbon Monoxide Calibration:

Obtain the 50ppm or 100ppm Carbon Monoxide from a certified Distributor and measure the
gas using a 100 to 300 cc per minute flow rate. Be sure to allow the reading to stabilize.
