The backlight of the screen is on followed by work sound of internal air blower coming out and the display screen displays all test values. The formaldehyde sensors and VOC sensors require preheating for working. It suggests making data reading 5-10 minutes after the equipment starts to ensure that the sensors work normally. The data refresh rate is 1 second.keys: -/cancel key: In the menu operation, press the menu page down. In value setting interface, press to carry out subtraction operation for the selected digit. Hold down not to save the current setting and return to the previous menu.Shift/menu key In the measurement menu, hold down to enter the menu interface. In the value setting interface, press to carry out shift operation for the selected digit.+/enter key:In the measurement interface, press to switch the measurement unit; in menu operation, press to page up the menu item. Press to carry out addition operation for the selected digit in the value setting interface. Hold down to save current setting and return to the previous menu. It displays success of setting and last 1 second.Equipment chargingThe equipment is equipped with 12VDC charging power supply with the charging current 1.2A and charging time 3-5 hours. During charging, the red indicator light means that charging is conducted. The blue indicator light means that the charging is completed. You may observe the battery level in a real-time manner after startup. Please make charging in time for the purpose of battery life. If it is out of use for a long time, please ensure that the battery is fully charged.Equipment alarmWhen the any item in alarm value setting is measured to exceed the alarm value and the alarm switch is at ON state, the equipment gives out alarm signal and the buzzer gives out short alarm sound of "click". Continuous reverse display on the measurement value of corresponding item and normal cyclic display indicates that the test item exceeds the set alarm value.Menu operationAlarm value settingIn measurement interface, hold down menu key to enter the main menu interface. Select the first item: 1 alarm value setting; hold down the enter key to enter alarm value setting. Select the items to be set by making switching between cancel key and enter key. After the item is selected, press the shift key to the setting value, and then set the digit by pressing the menu in a cyclic manner. After the setting is made properly, ensure that the selected digit is at any place of the set value, hold down the enter key to save the setting value and return to the previous menu. When the alarm value of the item is set as 0, the function is closed. Set on/off of the alarm function: the last one of the setting item is the alarm on/off. On indicates that the alarm function is opened and off indicates the alarm function is closed. Hold down the cancel key not to save the setting and return to the previous menu.Time settingIn menu interface, select the second item: 2 time setting; hold down the enter key to enter time setting. The hour, minute, second, year, month and day of the item are set through cyclic switching of the menu key. The set value may be increased or decreased through cancel key or enter key. After the time value is set properly, hold down the enter key to save the setting and return to the previous menu. Hold down the cancel key not to save the setting and return to previous menu.Output settingIn the menu interface, select item 3: 3. Output setting: Hold down the enter key to conduct output setting. The output is set with: 1 RS485 equipment address, 2. Baud rate; 3. report time. Press the enter key and cancel key to switch the setting item; press the menu key to enter the setting item. After setting is conducted properly, hold down the enter key to save the setting and return to the previous menu. Hold down the cancel key not to save the setting and return to previous menu.The RS485 equipment address scope: 1-240; the default equipment address is 001: The default Baud rate is 9600 (three types of Baud rate 9600, 19200 and 115200 are available for selection).
