Is there any way to test (With Digital Multimeter) Honeywell CSNA111 (Closed Loop Current Sensor) which was mounted on the Board (AC BRUSHLESS MOTOR CONTROLLER) ????
Short answer- yes. Long answer- you'll have to google on the part number, read the data sheets and figure out how to construct a small test bed that generates a variable test current as well as the appropriate low voltage supply for the DUT, then you can measure the response to the varying current with your DMM.
