18. TROUBLESHOOTING
Common problems are listed below. If you are unable to find a solution to your problem here contact
your moorLDI2 agent or Moor Instruments Ltd. There are no user serviceable parts in the moorLDI2.
Circuit diagrams and parts lists will be made available to approved service personnel upon request.
18.1 NO FLUX IMAGE DURING ACQUISITION
LD Photo Image black and/or Flux Image is all grey or blue:
1. Change the palette range to a lower value (or use Contrast).
2. Increase the gain levels using Scanner Setup
3. Check that the background threshold has not been set excessively high (e.g. reduce to 100 or
lower).
4. Check the power of the laser beam during a measurement .( Most easily done during a single
point measurement as the beam is stationary.)
5. For the IR (Infra Red laser ) imagers check the key switch is ON and Interlock in place. The
IR emission LED should be on during a measurement.
Image is all white:
1. Check the palette range: increase range or use Contrast.
2. Reduce the gain settings.
Poor photo image:
1. Check the palette range: increase range or use Contrast.
2. Increase the dc gain if photo appears dark and grainy (usingscanner setup).
3. Decrease the dc gain if photo appears white and bleached (usingscanner setup).
4. If the image is 'pixelated' this can be improved at measurement time by increasing the image
resolution using Scanner Setup, Image.
At image review the image can be presented more clearly using Interpolate and Smooth
functions.
18.2 SLOW COMPUTER RESPONSE
1. Insufficient memory.
This can occur when there are many other applications being run or there are too many files
open. Solve it by closing unnecessary applications and files or increase the available memory.
A fast and easy solution is to close down the computer and start again. However, a longer
term solution to memory availability should be found.
2. Slow processor.
Analysis of Repeat Scan images may be slow on older PC's. If this becomes a problem then a
computer with a faster processor is recommended.
