Metrologist, electronics engineer, small wind generators and hydro power plants enthusiast. Former glider pilot, university teacher.
Small own calibration laboratory, with 8.5 digit multimeters and calibrators. Capabilities: I can measure /generate Voltage dc: Resistance, Current dc with uncertainties 0.0003%...0.0007%, ratio with 0.00005%. Temperature 0'C ..100'C +-0.05deg C. Calibrate up to 8.5digit multimeters, check 24h or 200h stability, characterize Temperature dependence of resistance standard (R(T) curve).
