Note:
1. (cr)expresses carriage return. Its ASCII value is 0DH. (lf) expresses line feed. Its ASCII value is 0AH.
2. "d" expresses 0-9 number. 0 value is expressed as +0.000000E+00.
3. "d" expresses 0-9 numbers. There is no decimal point in integral part before "E".
4. dddddddd means the serial number of the instrument, t means the model of the instrument.
5. The character P can be added before every basic command. It means that the transferred data has CRC
