LaserBee I-X 2.1W LPM needs calibration

[steviedezie]

Ok i have no idea how it happened...one day i used my LPM and I got weird readings... They were wayyyy to high. I believe somehow that I need to recalibrate my LPM.

So is there anyone here that has a laser between 400-600mW thats stable for 1 solid minute + a working calibrated LPM that could recalibrate mine? I prefer someone close by as to keep shipping cost low and make it fast.

anyone anyone???

Hey steviedezie...

before you go playing with the calibration.... give me the info
written on the 2nd Spash Screen when you first turn on your
LaserBee I-X... You can send that info by PM....
I'll see if the calibration is actually off...

There is no way the calibration will become off unless the
Thermopile has been damaged or the calibration values have
been altered...

The calibration values are held in non volatile memory and do
not change on their own...:undecided:

I checked your 2nd splash screen data that you PMed me and your
2.1 Watt LaserBee I-X is still calibrated to the same value as when
it left the shop. It has not changed.

Your problem seems to be elsewhere. :thinking:
Have you checked the connections of the Thermopile to the PCB ??
Have you damaged the Thermopile's Sensor surface in any way ??
Did you let your LaserBee acclimate to the test area temperature ??
Did you make sure there are no other external sources of heat or
moving air in the test area ??
Try testing your Lasers at least 6" away from the Thermopile...
How much were the readings Wayyy over...???

the range was probably a percentage off, as the higher the power the worst it got. My 250mW red was reading 370mW, my 1700mW blue was reading 2050mW... I have checked the connections and it seems fine. There was one time i accidently had a laser that was focused down to a pin point hit the thermopile sensor for about 1 second...that was enough to leave a little 2mm long line on it. It must be from that damage then. weird thing was, that happened almost 2 weeks ago and it still ran fine then, just yesterday did it gave me weird readings...then again...it was over 95 degress where i live yesterday...could that explain the higher readings?

The 95 degree F temperature could very possibly be a factor...
We calibrate at a constant 70 degrees F.

Can you do a test in an air conditioned 70 degree F environment...
If so... let your Laserbee acclimate to the lower temperature for
at least an hour before doing any tests...

Thanks Jerry for all the help. I've got to say he's got the best customer service in town. Excellent post sale support.

Everything is working fine now. It was the really hot temperatures + a bad battery. Now that its powered by a 9V regulated PSU everything is A-Ok!!

Glad to hear all is as it should be...
Thanks for the update...:beer:
