Yes, it has. When the lower display shows "PoFF" you need to use ▲ or ▼ button to select the upper value to "yes" or "no"

“Yes” will activate Auto Power Off management. “No” will deactivate this function.

After you select the upper text to "yes" or "no", press Enter Button to save the settings.

When the lower display shows “Date” press Enter Button once, use ▲ or ▼ buttons to adjust the value (the setting starts from Year). After the desired value is set, press Enter Button again and you will start the next value adjustment. Next values to adjust will be Month, then Date, Hour, Minute and Second.

After setting all of the values (Year, Month, Date, Hour, Minute, Second), the screen will jump to "SD card Decimal character" setting.

Note: After the time value is set, the internal clock will run precisely even if the device powers off but only if the battery is under normal condition (not low).

For Auto Datalogging (set the sampling time: ≥ 1 second):

• Press REC Button once, the LCD will show the text REC, then press Logger button, REC will flash, at the same time the measuring data along with the time information will be saved into the memory circuit.
• While operating the Datalogger function, if you press Logger Button once it will pause the Datalogger function (stop to save the measuring data into the memory circuit temporally). In the same time REC will stop flashing.
• When you pause the Datalogger, press and hold REC Button for at least two seconds, REC indication will disappear and finish the Datalogger.

For Manual Datalogging (sampling time: 0):

• Press REC Button once, the LCD will show REC text, then press Logger Button once, REC will flash once and the Beeper will sound once, at the same time the measuring data along with the time information will be saved into the memory circuit. The lower Display will show the Position (Location) no. and the data will be saved into the SD card.
• Press and hold REC Button for at least two seconds, REC indication will disappear and finish the Datalogger.

Yes, it does. To prolong the battery life Aktakom ATE-1093 anemometer automatically turns off in 20 minutes. To deactivate this feature follow the below steps:

1. Turn off the anemometer.
2. Press and hold Backlight key while turning the meter on.
3. “dis APO” will appear on the display. Auto power off feature can be considered deactivated.

Note that Auto power off is re-enabled each time the anemometer is turned on.

Also note that Auto power off function is disabled in CFM/CMM or Average mode.

Yes, therefore while taking measurements press “HOLD” button to freeze the air velocity/air flow reading. HOLD indicator will appear in the bottom of the LCD.

To return to the normal operation you will need to press “HOLD” again.

1. Before changing the measurement unit you need to deactivate 2 functions: “Hold of the current value” and “Max/Min value”.
2. Keep “SET” button pressed for minimum 2 sec. until you see “Code” symbol at the bottom of the LCD.
3. Release “SET” button, you will see “1000” displayed at the top.
4. After you see both “Code” and “1000” symbols press “ENTER” to activate the function of the measurement unit change. “ESC” button will return the device to the standard measurement mode.
5. Using “SET” button set “°F”. Then press “FUNCTION” button to change the measurement unit. If you see “0” displayed at the top after you pressed “FUNCTION” the measurement unit will be “°C”. If after pressing “FUNCTION” there is “1” symbol displayed that means the measurement unit will be “°F”.
6. After you set the required measurement unit press “ENTER” in order to confirm and save the setting. “ESC” button will return the device to the initial state.

Yes, it does. If the left corner of the LCD displays "LBT" that means it is necessary to replace the battery.

However measurement may still be taken for several hours after low battery indicator appears before the instrument becomes inaccurate.

To replace the battery:

1. Slide the battery cover away from the instrument and remove the battery.
2. Install 1.5 V AAA (UM-4) battery x 6 PCs. After you install the batteries reinstate the battery cover.

ATT-9002 has a built-in auto switch off function that saves the battery life. In case there are no buttons pressed for about 10 minutes the device will be switched off automatically.

During the measurement, if you press "Sampling Check Button" once, the lower LCD display will present the Sampling time information in second unit.

Most (90% of typical applications) organic materials and painted or oxidized surfaces have an emissivity of 0.95 (pre-set in the unit).

Inaccurate readings will result from measuring shiny or polished metal surfaces. To compensate, cove the surface to be measured with masking tape or flat black paint. Allow time for the tape to reach the same temperature as the material underneath it. Measure the temperature of the tape or painted surface.

1. Install USB Host Diagnostics application on your Android device and run it.
2. Start diagnostics by clicking the key of the same name.
3. Follow the displayed instructions of the application.
4. After the diagnostics check the condition of Android API. «claims support = no, device detected = no» means your device IS NOT ready for operation with USB-devices.
5. In this case the application should offer to correct the error after the diagnostics and to restart Android.
6. Agree to the application by clicking «Ok» after that restart your device pressing the power button of the device.
7. Run the utility again and make sure the condition of Android API has changed for «claims support = yes, device detected = yes».
8. Now your device is ready to work with USB-devices.

If due to some reasons you do not have a chance to use this utility or would like to find more information by yourself you may search it online with the key phrases «android.hardware.usb.host.xml».

To make your Android-based device (tablet PC, smartphone) operate with connected USB-devices it should meet some requirement that you may find in the description of Aktakom Data Logger Monitor (ADLM-A). Here are some of the most important features to pay attention to:

1. Android settings should allow applications to use API USB-host functions. Some of Android-based devices do not provide such permit on default (as a rule these are specialized devices like television-game device or set-top box etc.).
2. To check this functions (whether they are allowed or not) on your Android device you may use for example free utility «USB Host Diagnostics» available on Google Play. This utility can in some cases install necessary permit in the system.

These converters fit different device types. To see which interface converter fits your device visit ACE-1025 and ACE-1026 pages.

Therefore you need to buy Aktakom Data Logger Monitor (ADLM-A).To connect USB converter you will need a special adapter – USB OTG.

This adapter is not included into the delivery set.

The data record function records the maximum and minimum readings. Press the "REC Button" once to start the Data Record function and there will be a "REC" symbol on the display.
