You canalso use the trigger model Simple Loop.When you use a reading buffer with a command or action that makes multiple readings, all readingsare available in the reading buffer. However, only the last reading is returned as a reading with thecommand.If you define a specific reading buffer, the reading buffer must exist before you make themeasurement.To make a power reading, use the smu.measure.unit command and set the units tosmu.UNIT_WATT for the voltage or current measurement function.
