For details, refer to "8.1 List of error codes" in this manual.
*2:
When calculated value is low, "MEA"LED, "R"LED, "1"LED and "3"LED are looked like flashing.
Comparing to the last value per measuring cycle, LEDs light while calculating, then LEDs light off upon
no changes.
Since measuring cycle is shortest as 10ms, short period setting seems like flashing.
