Calibration and maintenance: ensuring long-term accuracy
The card is integrated with EEPROM and stores factory calibration constants at the factory. Users can use the Auto calibration function to correct offset and gain errors without the need for an external signal source (preheating for 15 minutes is required). After calibration is completed, the new constants can be saved to the user area (up to 3 sets) for quick switching at different ambient temperatures. The calibration reference source is 5.000V, with a temperature coefficient of ± 2ppm/° C and a long-term stability of 6ppm/1000 hours, ensuring long-term reliability.
Software Support and Development Suggestions
Linghua provides MAPS (Measurement, Automation, and Platform Services) software suite:
MAPS Core: Includes device drivers and ACE management tools, configurable DMA buffers, aliases, etc.
MAPS/LV: LabVIEW development library and examples.
MAPS/C: C/C++API library and a large amount of sample code.
It is recommended to use ACE's Soft Front Panel to quickly verify hardware functionality when using it for the first time. For high-speed continuous acquisition, it is necessary to enable DMA and configure the scattered/aggregated list reasonably to avoid data loss.
