The base model is designed to provide part-per-million (ppm) read- ings of levels of CO within a range of 0-2000ppm. The instrument is available with an optional oxygen sensor which provides the percent of oxygen in air within a range of 0-25% volume. Additionally, an Air-Free CO feature is available on the CO/O2 version. With this optional feature, the instrument will calculate the elevated levels of CO related to increasing oxygen 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 base models can be upgraded by the factory or authorized ser- vice center with the required hardware and software additions. The sensors are electrochemical, which can be field calibrated. The sensors have a renewable filter which reduces cross-sensi- tivity and are economical to replace. By using the supplied hot air probe the instrument can evaluate CO and O2 levels from appliance flues or vents. The Sensit CO models can also be used as a personal monitor. The default factory alarm set point for carbon monoxide is 35ppm. The optional O2 sensor default factory alarm set points are less than 19.6% or greater than 23.5%. The display must be in view to determine the detected CO and O2 levels.

SPECIFICATIONS PRODUCT FEATURES ZERO/SAVE BUTTON MENU BUTTON POWER BUTTON HOT AIR PROBE BATTERY COMPARTMENT DISPLAY WATER/ PARTICLE FILTER IR COMUNICATION WARNING LED’s Sensit®CO instruments are constructed of high impact ABS plastic to withstand the rigors of field use. Incorporated in the hand grip area is the battery compartment. All Sensit®CO instruments models operate on “C” type alkaline batteries or NiMH (nickel metal hydride) batteries. The approved batteries are, PROCELL MN1400 Alkaline or equivalent and the PANASONIC HHR300CH NiMH battery or equivalent. The two line LCD continually updates PPM CO levels for the base model, percent oxygen level is added for the CO/O2 model and PPM “CF” is included for the CO/O2/air-free CO model. Regardless of the model, all instruments display all data simul- taneously on the LCD when in the work display. All models use a rotary vein pump to draw in the air samples. Flow block, low battery power and sensor failure alert will ap- pear on the LCD as needed. Warning systems for the operator consist of one audible alarm, omitting a tone from the speaker on the back of the instrument and two visual indicators on the front. One is a red flashing LED alarm light, the other is a flashing gas or optional oxygen read- ing on the LCD when the instrument detects readings at the alarm set point. All alarms indicate simultaneously unless the operator chooses to use the audible alarm mute feature. An infrared communication window is located on the right side to permit downloading of calibration data, data saved by the (Continued on page 5) Power Supply: 3 “C” Alkaline Batteries Sensor: Long Life Electrochemical Range: 0-2000ppm CO, 0-25% Oxygen for O2 model Alarm: 35ppm CO, < 19.5% or > 23.5% Oxygen for O2 model Alarm Range: 0-300ppm CO, 17.5% - 20.5% (low) for O2 model Warm Up: Less than 30 seconds Response Time: 90% of reading < 60 sec.

PRODUCT FEATURES continued from page 4 Battery replacement is necessary when the display reads BAT LOW, an audible alarm sounds and the green ready LED flashes. When BAT LOW is displayed, the instrument has approximately 30 minutes of useful operation time prior to shut off. CAUTION: Always change batteries in an environment free of combustible gases. Remove the battery sleeve cover by depressing the locking tab on the front of the handle with a coin or flat object and pulling the handle away from the top or display area of the instrument. Place 3 approved batteries into the battery holder. For best results hold the battery compartment so that it lays in your right hand. With your left hand install the battery that goes toward the front first. The battery that is in contact with the rear spring second and finally insert the third battery in the center by forcing the second battery such that the spring compresses and allows the batteries to go into place. If you do not use your right hand to hold the bottom of the battery compartment the batteries can come out. Observe the polarity markings on the inside of the battery holder. Improper installation will cause the instrument not to operate. Replace the battery sleeve and allow the locking tab to snap into position. Check to be sure the handle is secure to the instrument body by gently pulling the handle away. The handle will remain firmly in place if a proper connection is made.

If the display fails to illuminate or BAT LOW is shown on the display, replace the batteries. There is room in the carrying case 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, remove the instrument from service and 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 the factory. 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- curate readings and invalid tests. First, block the inlet of the instrument with your finger for ap- proximately 5 seconds. The display should read “FLOW BLOCKED” and a warning beep will sound if all seals are intact. This is a pass. However, if the flow block signals are not given, this is a failure and the instrument should be removed from ser- vice. Please consult the factory for repair. If the instrument passes, attach the hot air probe (#AJ0SCO705- 100) to the instrument. The connection need only be finger tight and requires approximately 1/4 turn of the fitting. Next block the end of the probe. Within 10 seconds the display should read “FLOW BLOCKED” and the audible warning will sound. ‘This is a pass. However, if the flow block signals are not given, this is a failure and the probe should be removed from service. Please consult the factory 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! 6. When sampling or testing areas with elevated temperatures such as an appliance vent or flues, always attach and use the supplied hot air probe (#AJ0SCO705-100). Failure to use the approved probe can result in inaccurate readings or damage to the instrument and may void the warranty. OPERATION AND USE

OPERATION AND USE continued from page 8 10 7. For models with the optional Air-Free CO calculation, the data will appear on the LCD in the form of PPM next to the “CF” designator. This calculation will only be presented when the oxygen level has dropped to 18.9% or less while sampling flue gas emissions. NOTE: Air Free CO levels or CF readings are calculated by the instrument based on CO and O2 levels detected during flue gas sampling. 8.
