Product characteristics
Product characteristics
1. By encoding and decoding the number of rounds of the table “direct reading” out of the word on the digital position of the physical compiler;
2. Photoelectric direct reading module with automatic detection of each photoelectric component performance and reporting function;
3. The table has a unique identification code, ie the table address (factory number);
4. “0” power design, failure rate reduced, longer life;
5. Photoelectric direct reading module completely sealed in the counter, and water isolation, from outside water and moisture erosion;
6. Meet the “electronic remote meter” (CJ / T224-2012) standards;
7. The use of advanced data encoding and verification methods, communication reliability is high;
8. Compliant with EMC, ESD, EMI and other electronic products, electromagnetic compatibility aspects of technical requirements.
