Internally the interval is the sum +of bus and shunt voltage conversion times multiplied by the averaging rate. We don't touch the conversion times and only modify the number of averages. The lower limit of the update_interval is 2 ms, the upper limit is 2253 ms. The actual programmed interval may vary from the desired value. -- 2.17.1
