• Zero Reset:Due to different environment and sensors own characteristics, gauges may have some zero drift after long period of using, which may affect the accuracy. Therefore, the gauges need to be reset at zero point before using. Otherwise it can not perform the normal accuracy. The gauges can get better accuracy if they can be reset at zero point after 7 days continuously using. In addition, users should repeat the zero reset operation in every 6 or 12 months, or when the deviation of the gauges exceeds permitted value.
