Learn to debug digital pressure gauge before use

The performance of digital pressure gauges has been continuously improved, and the variety has also been increased from a single barometer to hydraulic, active, and vacuum gauges. Digital pressure gauge has been accepted and approved by the majority of measurement workers because of its advantages of easy operation, stable performance and intuitive reading.

Digital pressure gauge debugging method (with -90 ~ 100KPa range meter as an example): boot, instrument display: model, range, accuracy. Automatically switch to KPa and mA at the same time; use the standard piston pressure gauge to pressurize the instrument to full scale 100.00KPa. At this time, there is an error between the instrument and the standard; press the pressure key to switch the KPa and mA display status of the instrument to KPa and mmH2O shows the status at the same time, can be full-scale adjustment; press the pressure, current key, the instrument shows FS ADJ B and instrument pressure value, press the backlight key once, the instrument automatically adjusts the full range, so that the display value is 100.00KPa and 10200mmH2O . And automatically exit the menu, full-scale calibration is completed; negative pressure full-scale adjustment steps and the same positive pressure; press the pressure, backlight key instrument display SET OFF then press the backlight key seven times the instrument shows the SET ON debugging menu to open the press key drop out. At the same time press the pressure, backlight key instrument display DEL SET DATD; press the pressure key once, display: range, accuracy, date, date. Before the factory, the manufacturer can adjust it well, it is not necessary to adjust; press the pressure key to display SET DP. To adjust the decimal point, the factory adjusts it before leaving the factory, no need to adjust; press the pressure key to display FS ADJ A as the correction linear full scale adjustment. No need to adjust; press the pressure key to display linearization as a linear correction, note: must be corrected for 1000 points (eg: 100.00KPa from low to high without increasing 10.00KPa, press the backlight key once, you can see the modified linear); Press the pressure key to display temp compensate as the temperature compensation key. The factory has adjusted it before delivery, and no need to adjust. Press the pressure key to display the same meaning as FS ADJ B and above 5; Press the pressure key to display SET ON as the instrument menu is open. Status, press the backlight key once, will close the menu

Digital pressure gauge features: Compact shape structure, one-handed operation, especially suitable for use in field and narrow places; Advanced microprocessor: timely correcting the zero point and linearity of the instrument to ensure the instrument's high in long time Accuracy; micro-power devices and large-capacity nickel-metal hydride (lithium-ion) battery, the instrument has a long working time without electricity in the field; instrument structure is compact, digital display is intuitive and clear; imported chassis, pull-out external battery, can be Any replacement; a multi-purpose machine, optional multi-digit digital module, a wide range of measurement.

The digital pressure gauge is a new type of test instrument that Jiangsu Jinhu Hongrun Instrument Co., Ltd. engages in production and development. It is an economical pressure measurement instrument designed by our company for more than a decade of experience in pressure instrument manufacture and field application. Its performance-cost ratio is better than that of Druck's factory in the United Kingdom. The instrument not only solves the calibration of standard pressure, but also better meets the on-site comprehensive testing needs.
