RTCA stands for "Radio Technical Commission for Aeronautics", a not-for-profit corporation formed to advance the art and science of aviation and aviation electronic systems for the benefit of the public, helps to develop standards to assure the safety and reliability of all airborne equipment. (http://www.rtca.org)
The "DO-160E", published by RTCA, is widely used as a standard for environmental qualification testing to show compliance with appropriate airworthiness requirements. "Section 21 of DO-160E" concerns the "Emission of Radio Frequency Energy". The tests in this section are performed to determine that the device does not emit radio frequency interference in excess of the specified limits. Every carry-on electronic device must comply with radio frequency emission and susceptibility guidelines outlined in "Section 21 of the RTCA DO-160E"" document, whether it flies in the passenger cabin or cargo hold. The "DO-160E" is recognized by the International Organization for Standardization (ISO) as a de facto for international standard "ISO-7137".
Our easy-to-use USB computer connection makes things not only simple, but allows you to connect several units at the same time.
With the attached software it is possible to view current measurements and current trends in a changing graph form. Graphs can be opened for the same number of units as are connected and can be simultaneously viewed.
One data set consists of readings for all channels in that type of unit: Temperature, Humidity, and Barometric Pressure. At the longest recording interval of 60 minutes, recording can continue consecutively for one year.
Our exclusive design and technology has allowed us to create a highly accurate yet compact and lightweight unit (55x78x18mm 62g) that is unbelievably affordable.
Using our specially designed low energy consumption circuit this unit can run on two AA alkaline batteries for up to one year of continued use. No need to worry about where you place it as the battery will allow you to measure and record over long periods of time whether the unit is in transit or in a distant place.
Battery life will depend on the recording environment, recording interval, communication frequency, and ambient temperature. The above battery life test was carried out using brand new batteries and in no way do we guarantee a battery's life.
By setting adjustment values beforehand, you can record and display the post-adjusted measurement values.
Possible to transmit one unit of full data (8,000 readings) to computer in about 11 seconds.
The easy to read large sized LCD displays present readings, recording condition, battery life warning, amount of data readings, and unit of measurement among other things.
1. Recording Mark
The recording condition will appear.
ON:Recording in progress.
BLINKING:Waiting for programmed start.
2. Data Capacity Scale
After every 2000 readings the scale will be marked from left to right.
3. COM Mark
This will appear when data is being sent or received.
ON:USB cable is connected.
BLINKING:In communication with computer.
4. Recording Mode
ONETIME: When the number of recorded readings reaches 8000, "FULL" will appear in the unit's LCD display and recording will automatically stop.
ENDOLESS: When the number of recorded readings reaches 8000, the oldest data reading will be overwritten and recording will continue.
5. Battery Life Warning Signal
When the battery power becomes low, this will appear in the LCD display. If the battery power becomes even lower, SLP will appear and normal operations will stop. If the signal appears, please change the battery as soon as possible.
6. Unit of Measurement
The unit of measurement for the display will appear.
7. Measurements and Messages Area
Current measurements or operational messages such as FULL or SLP will appear.
