SECTION 1 General Description The Model IAQ10 is a hand-held meter to measure Carbon Dioxide (CO ), displayed 2 in units of parts per million (ppm). An NDIR sensor in the top end of the meter measures gas content by diffusion through sensing holes. The IAQ10 ships in a pouch that provides a small amount of protection to the display and the sensing holes in the top of the instrument case. The instrument ships with batteries (which are not installed), a calibration sheet, and this

concentrations. This technique is called non-dispersive infrared (NDIR) detection. SECTION 3 Safety When using the IAQ10 to check for CO 2 values, make certain that you can safely raise and hold the instrument while making measurements. Be especially careful when working on a ladder. Observe all necessary precautions so that the unit does not become caught in moving machinery or touch any exposed electrical wiring. DANGER! Use with corrosive or other dangerous or explosive

SECTION 4 Setting-Up the Model IAQ10 Supplying Power The IAQ10 can be powered in one of two ways: four AA-size batteries or the optional AC adapter. Installing the Batteries Insert four AA batteries as indicated by the diagram located on the inside of the battery compartment. The Model IAQ10 is de- signed to operate only with alkaline batteries. When 15% battery life is remain- ing, the battery indicator will blink, indicating the batteries need to be changed. At 0%, “LO” will di

SECTION 5 Operation of the Model IAQ10 Note: Do not hold the instrument close to your face. Humans exhale CO and this will affect 2 the accuracy of the readings. When pressing the keys on the keypad, the Model IAQ10 will beep to confirm the function. If you press a key and the Model IAQ10 does not beep, the Model IAQ10 does not allow that function during the selected mode. (See Section 9 for informa- tion on disabling this feature through an internal DIP switch.) ON/OFF Key P

calibration. When the Model IAQ10 completes the internal self-check, it will display the approximate percentage of battery life remaining. Note: The sensor needs up to 10 minutes to stabilize in still air before displayed readings can be considered accurate. Moving the instrument may decrease this stabilization time. READ Key Carbon dioxide concentrations will be displayed in parts per million (ppm). The IAQ10 can be left in a room to monitor general conditions, but it is import

The display updates every second and each reading is the average of five samples. ( 5) Key The instrument only displays CO . 2 RECALL ( 6) Key Press the RECALL key repeatedly to display: minimum value (MIN), maximum value (MAX), average value (AVG), and number of seconds sampled (COUNT). Press the READ key to return to normal measuring mode. The instrument does not store readings. The information viewed in the recall mode is for the sample reading just taken. Once a new sam

SECTION 6 Maintenance of the Model IAQ10 The Model IAQ10 requires very little maintenance to keep it performing well. Case If the instrument case or storage case needs cleaning, wipe it off with a soft, damp cloth. Never submerge the IAQ10 in any liquid or allow any liquid to enter the sensing holes. Storage When storing the Model IAQ10 for more than a month, TSI recommends removing the batteries. This prevents possible damage due to battery leakage. SECTION 7 Service Inf

1. Turn the instrument off. Under the batteries, move DIP switch # 7 to ON. Turn the instrument back on. 2. Press and hold the READ key to begin the calibration procedure. The display will begin a countdown from 5 to 0. Release the key when the display reads 0. If the key is released too soon or too late, the instrument will go back to sam- pling in real-time. “ZerO” will appear on the display if the instrument is in calibration mode. 3.

Use 5 and 6 to adjust the concentra- tion displayed on the Model IAQ10 to match the concentration on the span gas cylinder. 8. Press and release the READ key to take a span gas reading. The Model IAQ10 starts a 60-second countdown. When the countdown reaches zero, the instrument returns t
