Table 1. Standard Meteorological (ASIMET) Parameters

Eac ASIMET module has C530 microprocessor and stored calibration coefficients handling conversion to scientific units capable of providing raw and calibrated data. The "C" command after address gets latest 1 minute average of calibrated data. "B" gets both calibrated and raw. "V" gets last 1 hour average. "L" lists all the settings including calibration coefficients.
