Screen:
7-inch true color TFT LCD (800 * 480 dot matrix)
Accuracy:
Real-time display: ±0.2% F.S.
Trace accuracy: ±0.2% F.S.
(Note: thermocouple should be removed from the cold end error)
Processor
Using high-performance ARM Cortex-M3 32-bit RISC core, can
simultaneously achieve multiple signal acquisition, recording, display and
multiple alarms
Storage module
The use of large-capacity parallel NAND FLASH flash memory chip to
store historical data, the use of serial FRAM memory chip to store system
configuration parameters and other key information
