GENERALDESCRIPTION

The Sensit®CO isahand held carbon monoxide analyzer.The

basemodelis designed to provide part-per-million (ppm) read-

ingsoflevelsofCOwithinarangeof0-2000ppm.

Theinstrumentisavailable withanoptionaloxygensensorwhich

provides the percent of oxygen in air within a range of 0-25%

volume.Additionally,anAir-FreeCO feature is available onthe

CO/O2 version. With this optional feature, the instrument will

calculatetheelevated levels of COrelatedtoincreasingoxygen

levels detected in appliance flue gas emissions. This informa-

tion is presented in PPM as “CF” on the display.

All model options can be specified at the time of ordering or

vicecenterwiththe required hardware and software additions.

tivity and are economical to replace. By using the supplied hot

air probe the instrument can evaluate CO and O2 levels from

display,replace the batteries.There is roominthecarryingcase

to keep an extra set.

3. If a sensor is past the intended calibration cycle, CAL DUE

will appear during the start-up sequence. Calibrate the instru-

ment before placing it in service. If calibration is unsuccessful,

removetheinstrumentfromserviceand consult the factory.

4. If the instrument detects an inoperable sensor an ERROR

message will flash during the warm-up. The display will also

show “FAIL”. Remove the instrument from service and contact

thefactory.

OPERATION AND USE continued from page 7

5. Prior to use, test a running instrument and hot air probe for

air leakage.Air leaks can cause diluted samples, provide inac-

curatereadingsandinvalidtests.

First, block the inlet of the instrument with your finger for ap-

proximately 5 seconds. The display should read “FLOW

BLOCKED” andawarning beep willsoundifall seals areintact.

This is a pass. However, if the flow block signals are not given,

thisisafailureandtheinstrumentshouldberemovedfromser-

vice.Pleaseconsult the factory for repair.

Ifthe instrumentpasses,attach thehotair probe(#AJ0SCO705-

100)totheinstrument.The connection need only be finger tight

andrequiresapproximately1/4turnof the fitting. Next block the

end of the probe. Within 10 seconds the display should read

“FLOWBLOCKED”andtheaudiblewarningwillsound.‘Thisis

consultthefactory for repair.

CAUTION: Do not handle the steel portion of any hot

air probe during or too soon after sampling. It will be-

come hot and retain heat and burns may occur!

Any sensor that does not meet the specifications listed in this

manual may require calibration or repair. A calibration check

does not update the calibration due date. Full calibration is
