Function description

There are two working modes of illuminometer, normal mode and setting mode. Each working mode has multiple interfaces:

Normal mode

1. Real-time interface: display current measured value of illumination and temperature.
2. Max value interface: record from startup, display maximum value of illumination and temperature.
3. Min value interface: record from startup, display minimum value of illumination and temperature.
4. Difference value interface: display the difference value between the latest measured value of illumination and enter the saved value when first entering the interface.
5. Holding interface: when the current measured value of illumination and temperature is no longer updated, the data remains unchanged.
6. Integral interface: the integral of the current illumination value against time (unit: hour).
7. Integral averaging interface: within the specified time(unit: hour), the average of illumination value integral against time.
8. Manual storage interface: you can manually save the current illumination value by pressing the button and can check the total groups of manually stored data (storage mode), with the maximum capacity of 60 groups. You can manually refer to certain illumination data or delete all manually stored data.
9. Automatic storage interface: you can set the timing period, and the illumination value will be automatically recorded; you can refer to the total groups of automatically stored data (storage mode), with the maximum capacity of 2000 groups; you can manually refer to certain illumination data or delete all auto-stored data.

Note: The integral operation and automatic storage operation can be turned on at the same time. If successful, “E” and “REC” at the top of the screen will flash.

Setting mode

1. Manual storage setting interface: set manual storage on and off.
2. Auto storage settings interface: set automatic storage on and off.
3. Display unit setting interface: set unit of illumination value (Lux/F) and temperature value unit ( C/’F)
4. Timing shutdown setting interface: set shutdown timing on and off without button operation
5. Bluetooth switch setting interface: set Bluetooth on and off (Bluetooth version only)

Host and PC connection

Host and PC connection (Bluetooth version only)

The computer terminal App (LuxMeter) is the reference software of UART serial port communication, through which the operation and use of the illuminometer can be more convenient. Through the computer side App, you can do the following.

1. The illuminometer parameters can be set more conveniently through this App, such as:
   • Whether to turn off or turn on the automatic shutdown function.
   • Setting of automatic shutdown time.
   • Whether to turn on automatic storage.
   • Automatic storage cycle setting of the instrument.
   • Setting of units.
2. Read the stored data in the instrument through this APP, or directly delete the stored data in the instrument.
3. Through the real-time measurement function of this software, the real-time measurement function data of the instrument can be synchronized to the App, and the curve data can be generated for easy analysis, etc.

Note: please refer to the help options in this APP for specific operations.

1. Please download the LuxMeter software installation package (including instructions) at the following website: http://www.benetechco.net. After typing the website, press enter to find the menu “Support – Download center” as shown on the left, and click to enter the page and find the installation package “LuxMeter UART v2.1.zip” as shown in the picture on the right. Click the Download button to directly extract the “zip compression package” after downloading. First install UART to USB cable drive Mete (software installation includes), and then install LuxMeter v2.1.exe.
2. According to the installation wizard dialog box prompt to complete the installation operation.

Note: the installation directory is recommended not to be placed in the operating system partition, which helps protect data from being lost when the computer reinstalls the system.

1. UART interface is developed for professionals in research institutes, companies, schools, etc.
2. UART interface must be connected to computer through specialized UART-USB line provided by our company;
3. Before using reference software, the driver of chip Prolific PL2303 must be installed (WIN10 comes with it and needs no installation, which can be automatically recognized after plugging in UART-USB line);
4. Before connecting reference software to the instrument, first set COM port for software. Refer to device manager in computer for COM port number, as shown in the picture below (under WIN7 environment):

Note

1. If COM port number is not selected right, reference software cannot be connected, and communication fails.
2. The default baud rate of the LuxMeter software connection is 9600bps, which does not need to be modified under normal circumstances.

Besides, if you need our protocol to develop and research, please contact with our sales department. The price of the purchasing protocol is RMB 500.
