Haven't tried to do much with mine yet. I did check the uncoated sensor I got along with the coated one and it seemed to be pretty close to what my other LPMs measure. I have a micro USB to USB 2 cable coming that should allow me to use the other sensor. The only thing that I would change is to have the meter in a case. I just keep it wrapped up in the ESD bag it came in.
Thanks for getting back to me.Whoops.. sorry for late response.
So you wish to calibrate the LPM?
I thought i already give a simplest manual.
Yet it seemed the manual still giving an unclear procedure..
I will rewrite the calibration process on the manual.
The thing is that you cant re-calibrate the Cuprum by user side.
The Cuprum intended for limited user so that it's locked, sorry.
Here is the recalibration process (without computer):
- enter the calibration menu
- press DOWN (about 10 secs)
- shine a stable laser with known power onto the sensor's surface.
- when the display/reading doesn't increased anymore (it will still change up and down within the last two digits because of noise), press UP to lock the calibration.
About the calibration, i'm sure your coherent sensor is calibrated using 1064nm laser
My reference is calibrated using alexandrite laser
and it's calibrated by the sole Ophir distributor in south east Asia region (including Indonesia), here is the website: InnoV Global | Premier Supplier of Photonics Products
It is indeed giving a higher value compared to my other reference sensor which is calibrated using 1064nm laser.
Hope this help
