Question: How many parameters can the DR2800 measure?
Built-in 247 test methods, most of the substances in the visible range can be measured

Question: The self-built curve of DR2800 cannot be stored, and it disappears after switching on and off after storage?
This happens when the battery voltage of the motherboard is lower than 2.5V. Replace the motherboard battery.


Question: DR2800 can't be turned on, it will shut down automatically when it starts flashing?
The battery of the main board is out of power, which will cause this situation. In addition, the external power supply is unstable, and the power board failure will also cause this situation.


Question: How does the DR2800 build its own curve?
User-created programming. Before starting programming, an analysis program must be developed. The user must define or determine the program sequence, calculation formula, measurement wavelength, coefficient, measurement range limit, etc.
• Modified tests.
• For commonly used tests, user programs can be assigned to the frequently used program menu.
• Specific options for creating methods and tests.

1. Press the user program in the main menu, then press the program option
2. Select New from the program options
3. Select 950-999 from the program number, select an unused serial number as the program number and press OK
4. Name the program name
5. Edit program type
6. Set the measurement unit
7. Set up the chemical structure
8. Perform calibration by entering calibration values
9. Stored procedures


Problem: The buttons on the DR2800 touch screen are not working and cannot be operated
The touch screen is broken and needs to be replaced. The article number is LZV611

Problem: DR2800 keys are offset and cannot be operated
