Zero and range adjustment
The zero point and range adjustment of the transmitter can be adjusted locally through the button of the transmitter itself; It can also be adjusted remotely through the handheld terminal. The specific method is: after the zero pressure is stabilized, press and hold the Z and S keys (Z is zero adjustment and S is range adjustment) for 5 seconds to release, press the Z key for 2 seconds to adjust the zero point, and press the S key for 2 seconds to adjust the full range after the full range pressure is stabilized. Note: the zero calibration adjustment range is 8% of the pressure range, and the range calibration range is 30% ~ 100% of the pressure range, which can be continuously adjusted. After adjustment, cover the sealing cover and tighten it.
trait
1. has the ability of automatic compensation, which can automatically compensate the nonlinearity, temperature drift and time drift of the sensor through software. Self-diagnosis can be carried out, and the sensor can be self-checked after power-on, to check whether all parts of the sensor are normal and make a judgment. Data processing is convenient and accurate, and data can be automatically processed according to internal procedures, such as statistical processing and eliminating abnormal values.
2. It has two-way communication function. Microprocessor can not only receive and process the sensor data, but also feed back the information to the sensor, thus adjusting and controlling the measurement process. Information can be stored and memorized, and the characteristic data, configuration information and compensation characteristics of the sensor can be stored.
3. It has the function of digital output interface, and can conveniently connect the output digital signal with a computer or a field bus. ● High precision
