Abstract
This is an easy-to-use pressure gauge calibration apparatus, which uses a pressure gauge as a standard device and is not affected by an order of calibration pressure points or pressure holding time. The pressure gauge calibration apparatus includes a pressure gauge serving as a standard device, the pressure gauge being calibrated in advance by a calibration procedure to repeat necessarily restoring a predetermined pressure state after data acquisition at each calibration pressure point, and adjusting pressure to a subsequent calibration pressure point, a pressure generation control device, a shut-off valve, and a measurement control unit.
