Usage operation:

1. Power on, key: Press the "on" button to turn on, and the LCD will display the measurement status; Press the 'off' button to shut down the instrument panel and cut off the power supply.

2. Zero calibration button: Before measurement, press the "Zero calibration" button once, and the instrument will automatically collect the zero value of the sensor and send it to the CPU for processing, ensuring that the data measured by the instrument is actualPressure value.

3. Pressure button: After turning on, the pressure unit of the instrument is displayed in the lower right corner of the LCD. If you press the "Unit" button during use to make the LCD display any unit of "MPa, KPa, Psi, Bar, mmHg, Kgf/cm2", press the "Pressure" button, and the instrument will automatically switch to the factory set pressure single level. When the measured current needs to be displayed, press the "Pressure" button when the instrument display unit is MPa (or KPa), and the corresponding current indicator light on the panel will light up, indicating the measured current state.

Precautions for use:

1. The instrument should be placed in a dust-free and non corrosive environment. If there are special requirements, please specify them in the contract.

When the instrument is not in use, the power should be turned off. If it is not in use for a long time, it should be charged once every three months.

3. The instrument has sufficient overload capacity, but do not overload it severely, otherwise it will cause damage to the sensor and render the instrument unusable.

4. Instrument sensors belong to high-precision products, and the surface of the silicon diaphragm should not collide with solids, otherwise it will damage the sensor.

5. Without professional testing skills and specialized testing equipment, do not open the hood for maintenance, and do not adjust internal components or replace materials, otherwise the reliability of the instrument cannot be guaranteed.

6. Do not let electric soldering irons or other heating elements near the display screen to prevent burning and damaging the plastic material.

7. Do not use chemical solvents such as gasoline and alcohol to clean the panel.

Although the instrument has seismic design, it should still be handled with great care and not dropped or collided when used on site.

Introduction to Precision Digital Pressure Gauge:

The precision digital pressure gauge adopts imported MCU and high-resolution AD converter, which can meet the requirements of high precision and low power consumption. Large screen LCD display, clear and easy to read data. The shell is made of stainless steel, which is corrosion-resistant and resistant to mechanical pressure. The entire body adopts sealing technology and can be applied in various complex environments. It is an ideal choice to replace traditional mechanical watches. It can be used as a high-precision calibration standard (gauge) to calibrate and verify pressure/differential pressure transmitters, pressure sensors, pressure switches, ordinary/precision pressure gauges, etc. It can also be used for online pressure measurement. This product is widely used in metrology, school research, natural gas, power, metallurgy, petroleum, chemical and other metrology departments for inspection and measurement.
