Release：999 instrument maintenance network time：2019-11-19

Some users are unable to complete the correction when using the exact colorimeter, so what is the cause? Below is a simple analysis of the causes of the failure and maintenance solutions for you, interested users may wish to have a look!

1. Unable to find the calibration plate
For example, the exact whiteboard is clean, but it always reports an error when making correction: "no correction board is detected. Confirm that the instrument is in the upright position and press continue to try again. "
Once upon a time, this mistake made me think it was a fake act. But later, I disassembled it and cleaned it thoroughly. Yes, I have received systematic training to clearly understand what's in its belly. After opening it, I found it was very dirty. After cleaning it up, I still reported an error. Then I connected it to the maintenance software and went through the official calibration process which is about 2000 steps. Then it was OK. Then I used the standard. Quasi color brick test its measurement data, and just as when the factory!
It's not hard for a careful partner to see that the above passage contains several key messages:
First, the author has been trained to do disassembly operations
Secondly, sometimes the appearance is not clean enough, and the dirty inside is more terrible
Third, the author has standard color brick and maintenance and correction software
Fourth, the data of the calibrated instrument is very accurate, reaching the factory condition.
If you can dig out these pieces of information, I am very pleased.
2. Base offset
Some of my friends may accidentally knock on the impact, which is more serious. In addition to psychological click, after all, such expensive equipment, please pay attention to whether the base is offset at the same time.
The simplest way is to rush the measuring head of the machine to yourself, slowly close the machine, do the normal measurement action, and see whether the small circle of the target window falls on the center of the measuring head. If it has obviously deviated from the center, the measurement data will be unstable at this time.
3. Lock failure
The author has noticed that there are some machines with lock failure on the side of the exact due to human or other reasons. The specific performance is that the instrument cannot be locked, only a certain angle can be presented. It does not affect the measurement, but affects the carrying, which causes great inconvenience to the daily use.
