Safety Precautions If you are using this product for the first time, please pay attention to the following: At the beginning of measurement, first open the needle valve on the instrument measuring pipe, and then adjust the flow with the flow valve on the panel.
Ⅰ、Product Characteristics 1. Self calibration: the sensor probe can automatically calibrate the zero point, automatically eliminate the system error caused by zero point and drift, and ensure the accuracy of each measurement. 2. Easy operation, large touch LCD screen. 3. Fast gas saving: after starting up and entering the measuring state, the time for each purity measurement is about 2 min.
Turn on the power switch of the instrument, and the instrument enters the process of initialization and self calibration. 3. Check power When using the internal battery for power supply, the upper right corner will display the battery capacity. If the battery capacity shows the red power shortage sign, please charge it as soon as possible before continuing to use.
5) When measuring the purity of SF6, adjust the flow to about 0.3 SLM (standard liter per minute). 5. Store data After the measurement data of the equipment is stable, you can save the data, press the "menu" text on the screen, call up the main menu interface, select "print data", you can print out the current test data, select "save data", you can enter the data saving interface.
Select "view record" function in the main menu interface. Enter the history view interface, press the "↑" and "↓" arrows at the bottom, you can turn records up and down, and press the right down button to print the currently viewed history.
Select the "modify time" function in the main menu to enter the time modification page. According to the above format, enter the current time, and press the right-click time modification button to finish the modification. Press the "←" arrow to cancel the modification and keep the original time unchanged.
Ⅳ、Matters needing attention 1. The instrument shall be placed in a safe position to prevent damage and violent vibration. 2. The instrument shall be charged in time before use. 3. When charging, just connect the power cord to the AC socket without turning on the power switch, and the instrument will automatically charge.
