1、 Product Features of Blue Screen Battery Recorder
The TXR2900E paperless power recorder is a new intelligent recording instrument with advanced 32-bit CPU as the core, supplemented by large-scale integrated circuits and graphic LCD displays. The instrument displays a large amount of information, is easy to operate, and has a friendly interface. The main functional features are as follows:

◆ Adopting high-performance ARM Cortex-M3 32-bit core, it can simultaneously achieve multi-channel signal acquisition, recording, and display

◆ Can directly input voltage and current signals;

The numerical range for displaying engineering quantity data is wider, and it can display 4-digit values: -999~9999;

The copy and paste function of the clipboard facilitates user parameter settings;

◆ Support external micro printers to manually print data and curves, meeting users' on-site printing needs;

Equipped with standard USB interface, supporting USB 1.1 and 2.0 USB flash drives, historical data transfer is fast and convenient;

Standard serial communication interfaces: RS232C, RS485, and CAN, supporting Modbus RTU protocol,

The instrument integrates hardware real-time clock, which can run accurately even in the event of power failure, making it more convenient for enterprise measurement management;

6. Record interval: 1 second to 240 seconds, divided into 11 levels: 1/2/4/8/12/24/36/60/120/180/240 seconds optional;

7. Recording time: The length of recording time is related to the capacity of FLASH memory, the number of input points, and the recording interval. The calculation formula is as follows:

Without losing power, the total recording time T can be calculated based on the recording interval t, and the calculation formula is as follows:

T=0.925×t；

Among them, the unit of T is days;

The unit of t is S;

For example, in the case of t=240S, each channel can record a time of T=222 days.
