1. GENERAL CHARACTERISTICS HD21ABE and HD21ABE17 IAQ Monitors are bench-top/portable instruments manufactured by Delta Ohm for the analysis of indoor air quality (IAQ, Indoor Air Quality). The instruments simultaneously measure the parameters: CO2 Carbon Dioxide, CO Carbon Monoxide and Atmospheric Pressure. The HD21ABE17 instrument also measures Temperature and Relative Humidity, and it calculates Dew Point, Wet Bulb Temperature, Absolute Humidity, Mixing Ratio and Enthalpy.
2. THE USER INTERFACE The user interface consist of a backlit LCD graphic display, and the power-on and setting keys. When battery powered, and not pressing any key, the backlight turns off after about 1 minute. To turn it back on, press any key. When using an external power supply, the backlight is always on. Turn the instrument on and off with the ON/OFF key. When you turn the instrument on, the logo and model will be displayed for a few seconds, and then the main display.

Display of all other quantities. Current date and time.
2.3 THE KEYBOARD The keys on the instrument perform the following functions: ON-OFF/AUTO-OFF key It turns the instrument on and off. When turning the instrument on, the first screen will be displayed. After few seconds the measured quantities will be displayed. + Auto Power Off The instrument has an AutoPowerOff function that automatically turns the instrument off after about 8 minutes if no key is pressed.
Key ◄/FUNC ◄ allows navigation through the menus. FUNC: In normal view, it allows to select the statistical data: maximum, minimum, and average. Key ▲ It allows navigation through the menus. During normal operation, it is used to select the resetting of the statistical data and to scroll the displayed quantities. Key ▼ It allows navigation through the menus. During normal operation, it is used to cancel the resetting of the statistical data and to scroll the displayed quantities.
3. OPERATION During turning on, the following message is displayed for about 10 seconds: Model HD21ABE17 Indoor Air Quality Firm.Ver.=01.00 In addition to the Delta Ohm logo the instrument code and the firmware version are displayed.

4.5 PROBES CALIBRATION The instruments and sensors are calibrated in the factory; no calibration is usually required by the user. However, you can perform a new calibration. You can perform the calibration of the CO (Carbon Monoxide) and CO2 (Carbon Dioxide) sensors. With the HD21ABE17 instrument you can also perform the calibration of the RH (Relative Humidity) sensor. No calibration is allowed for the Temperature sensor (HD21ABE17).
PROBE CALIBRATION CALIBRATION CO2 1) Offset only calib 2) 2 Pts Calibration 3) Restore Fact cal ▼▲ select exit/cancel confirm The CO2 sensor can be calibrated: • • In 1 point: only the sensor offset is corrected, the point can be any value between 0 and 950 ppm. In 2 points: the sensor offset and slope are corrected, the lower point can be any value between 0 and 950 ppm, the upper point can be any value between 1000 ppm and the full scale of the instrument. 1 point calibration: 1.
8. If the nitrogen bottle was used, close the bottle valve, remove the tube from the HD21AB17.9 accessory and remove the accessory from the instrument. Calibrazione in 2 punti: 1. Place the instrument in an environment with known CO2 concentration between 0 and 950 ppm (for ex. in clean air). For 0 ppm calibration with nitrogen bottle (code MINICAN.12A), slide the HD21AB17.
14. Adjust the value by using the arrows ▼▲. 15. Press ENTER on the instrument and wait the time necessary for calibration without changing the working conditions. 16. When the “CALIBRATION GOOD” indication appears, press ESC to return to the calibration menu. Restoring the factory CO2 calibration: In case of erroneous execution of the calibration procedure, it is always possible to get back to the factory calibration by selecting the 3) Restore Fact cal calibration option.
4.5.2 CO Calibration You can calibrate the zero of the CO sensor in clean air (the CO concentration is lower than 0.1 ppm outdoor) or using nitrogen bottles (code MINICAN.12A). Use the arrows ▲▼ to select the 2) Calibration CO item: PROBES CALIBRATION 1) Calibration CO2 2) Calibration CO 3) Calibration RH ▼▲ select exit/cancel confirm Confirm with ENTER.
CO zero calibration with nitrogen bottle (code MINICAN.12A): Using a screwdriver, open the back small door of the instrument. Connect the tube from the MINICAN.12A bottle with the rubber cap on the CO sensor head. Back door CO sensor Use the arrows ▲▼ to select the 2) Calibration CO item: PROBES CALIBRATION 1) Calibration CO2 2) Calibration CO 3) Calibration RH ▼▲ select exit/cancel confirm Confirm with ENTER.
Confirm with ENTER. The following screen will appear: PROBES CALIBRATION CO CALIBRATION CAL ZERO Cal zero 0 ppm exit/cancel confirm • • • • • Wait about 15 minutes before continuing. Supply the gas adjusting the bottle flow meter to get a constant flow from 0.1 to 0.2 l/min. Press ENTER and wait the two minutes necessary for calibration without changing the working conditions. At the end, close the bottle spigot and remove the cap from the CO sensor. Insert the protection grid.
3. Select 2) Set sensitivity and confirm with ENTER. The following screen will appear: PROBES CALIBRATION CALIBRATION CO SENSITIVITY SET Sens CO 50 nA/ppm 0 ppm ▼▲ set exit/cancel confirm 4. Use the arrows ▼▲ to change the CO sensor sensitivity value, and confirm using ENTER.
4.5.3 RH calibration (HD21ABE17 only) This procedure applies to HD21ABE17 instrument. Before starting the calibration operation, you should check if you need a new calibration using the saturated solutions at 75.4%RH and 33%RH: You should proceed with the calibration, only if you find an error in one of the two above calibration points. The calibration procedure removes the previous calibration data. For a correct calibration of the sensor, the first point should be 75%RH and the second point 33%RH.
4. The probe and the saturated solution for this operation should have the same temperature, and therefore should be located in a room with a stable temperature for the entire calibration period. 5. Unscrew the probe protection; screw the M12×1 threaded ring. 6. Should there be any liquid inside the measuring chamber, dry it with some blotting paper. The formation of liquids inside the measuring chamber, does not impair the measurement uncertainty of the solution or measurement. 7.

• Some keys are disabled during logging. The following keys are enabled: MEM, MENU, ENTER and ESC. • Pressing the MEM and MENU keys has no effect on the logged data if these keys are pressed after starting the recording, otherwise the following is valid. 5.1.3 Print function Press ENTER to send the measured data directly to the USB port, in real time. The printed data units of measurements are the same as those used on the display. The function is started by pressing ENTER.
6. INSTRUMENT SIGNALS AND FAULTS The following table lists all error indications and information displayed by the instrument and supplied to the user in different operating situations: Display indication Explanation ---- This appears if the sensor relevant to the indicated physical quantity is not present or is faulty. OVFL Overflow appears when the probe detects a value that exceeds the expected measurement range.
7. BATTERY SYMBOL – MAINS POWER SUPPLY The meter is provided with a pack of 4 x 1.2V-2200mA/h Ni-MH rechargeable batteries, placed in the battery compartment. The battery symbol on the display constantly shows the battery charge status. To the extent that batteries have discharged, the symbol "empties". When the charge decreases still further it starts blinking. In this case, batteries should be replaced as soon as possible.
7.2 NOTES FOR THE BATTERIES USE • • • • • • • • • At the first start up, it’s necessary to completely recharge the batteries. The charge time of the batteries package is about 4 hours. The last of the batteries package in measurement working mode is about 8 hours. A new Ni-MH batteries package reaches the maximum of its performance only after being discharged and charged completely again at least twice or three times. The batteries package autonomy depends on the instrument use.
8. INSTRUMENT STORAGE Instrument storage conditions: • Temperature: -25…+65°C. • Humidity: less than 90% RH without condensation. • During storage avoid locations where: • humidity is high; • the instrument may be exposed to direct sunlight; • the instrument may be exposed to a source of high temperature; • the instrument may be exposed to strong vibrations; • the instrument may be exposed to steam, salt or any corrosive gas.
