    Abstract: A method of manufacturing using a mass flow controller (MFC) includes closing a valve installed in a flow path of the MFC to prevent a fluid from flowing therein due to a closure of the valve, determining that the fluid is not leaking, determining that the fluid is stabilized, determining that a pressure sensor is normal, calculating a zero point calibration value of the pressure sensor based on a zero point of the pressure sensor, a time when power is supplied to the MFC, and a time when a flow is supplied to the MFC, applying the zero point calibration value to the pressure sensor, and measure the mass flow rate through the flow path with the pressuring sensor and adjusting the valve based on the mass flow rate to regulate the flow of the fluid to a manufacturing device.

    Abstract: A method of calibrating a zero point of a mass flow control device includes closing a valve installed in a main flow path of the mass flow control device to block the main flow path and prevent a fluid from flowing in the main flow path, determining, based on a pressure value measured using a pressure meter installed in the main flow path, whether the fluid has stopped flowing, determining, based on a flowrate value measured by a flowrate sensor provided on a sensor flow path connected to the main flow path, whether the fluid is stable, calculating a zero point calibration value based on a temperature value of the fluid measured by a thermometer installed in the main flow path and the flowrate value measured by the flowrate sensor, and applying the zero point calibration value to a zero point of the flowrate sensor.

    Abstract: An electronic device includes a display; a camera; a memory; and a processor operatively connected to the display, the camera, and the memory where the memory stores instructions which, when executed, enable the processor to determine a number of at least one source frame per unit second based on a specified maximum exposure time, receive light reflected from an external object by using the camera, for an exposure time determined according to a specified exposure value, generate source frames based on the received light, and generate a time-lapse image including at least one target frame indicating movement of the external object based on source frames, and the instructions cause the processor to generate the source frames at a speed different from a speed at which the time-lapse image including the at least one target frame is played.
