Part Number: DLPNIRSCANEVM
I'm trying to make continuous measurements with DLP NIRscan EVM.
However, when measuring continuously by repeatedly pressing "Run New Scan" button, an error often occurs and measurement becomes impossible.
The logfile when the error occurs is shown below.
In this state, the measurement cannot be resumed unless the power of DLP NIRscan EVM is turned off once.
Why does it happen and how can I perform stable continuous measurement without error?
I'm using NIRscan SW(version 2.0) and DLPC350 Firmware(Version 2.0.0).
Welcome to DLP forum and thank you for interest in DLP technology.
Could you please upload the screen capture of GUI?

In reply to Vivek Thakur:
Thank you for your reply.
Excuse me, may I ask you a question about GUI you write in your reply?
What does GUI mean?
Is it about "Matrix Application Launcher", controlling DLP NIRscan EVM via Web browser?
I don't understand what screen capture to upload.
In reply to Takashiii:
I am sorry, I misinterpreted for the NIRScan Nano EVM.
The DLPNIRScan EVM is a very old design and our team has very limited knowledge on it. I need to seek help from folks who may have worked on it in the past.
Now due to holiday time, I may have an answer after the week of 4 Jan.
Thank you for your patience.
OK. I'm looking forward to your reply.
Have a nice holiday!
Have a nice holiday.
It appears to me that this error is happening because a second scan is initiated before the first one is complete. Would it be possible for you to try inserting a delay between the repeated "Run New Scan" commands?
Also, may I know what is the purpose behind repeated "Run New Scan" commands? The web interface provides an option to specify "Number of scans to average". It would be better to increase that number in order to perform multiple scans and average the results.
In reply to Sreeram Subramanian:
I see.I will try to insert the waiting time between the repeated "Run New Scan" commands.
My purpose is to get time series data of the spectrum by repeating the measurement.I use Selenium (a portable framework for testing web applications) to operate automatically the web interface(DLP NIRscan browser).I want to prevent errors during measurement in order to get time series data.
Thank you. Please let us know if this resolves the issue.
I tried inserting a waiting time , which was about three times time from pushing "Run New Scan" button until the graph of the measured spectrum was output, between the repeated "Run New Scan" commands.
However, after several measurements, the measurement does not end with the screen shown in the image below.
In this state, measurement cannot be performed unless the power is turned off once.
May I know why increasing the "Number of scans to average" will not be acceptable for what you are trying to achieve?
