7 APPENDICES
7.1 PRECAUTIONS AND SYSTEM MAINTENANCE
When handling the colorimeter, avoid touching the glass window. The window is recessed and therefore protected
from dirt during normal usage. However, if it does require cleaning:
at first, blow short bursts of clean, dry air onto the window
if dirt has not been removed, use an optical lint-free cloth dampened with distilled water and gently wipe the
window without applying excessive force
in the case of a very soiled surface, contact Eoptis for support.
Occasionally wipe the outside of the meter with a soft water-dampened cloth. The housing components are made out
of synthetic materials. Thus, avoid contact with acetone and similar detergents that contain solvents. Remove any
splashes immediately.
The device is designed for indoor use. Extended exposure to bright sunlight, rain, dusty environments, etc. may
damage the electronics and the optics of the system. Avoid excessive shaking, dropping or mishandling of the device.
7.2 TROUBLESHOOTING
Problem
The EOPTIS logo on the device display is off after having connected the USB cable to the PC.
Solutions
1) The drivers are not correctly installed: check proper driver installation section and, in case the CLM194 is
not displayed, install drivers. To check the Device Manager to confirm that installation was successful, go
to the Windows -194
Colorimeter" under the "Ports (COM & LPT)" section.
2) The USB port is not capable of supplying full current (500mA): change port or disconnect USB devices
(such as external hard drives and speakers) which are connected to other ports.
3) Operating condition undefined or excessive EMC load: unplug and reconnect the USB cable, then re-start
the software.
Problem
The usb cable is plugged but software displays "Device not connected" and the green "M" indicator is off.
Solutions
1) Drivers are not properly installed: check proper driver installation section and, in case the CLM194 is not
displayed, install drivers. To check the Device Manager to confirm that installation was successful, go to
-194 Colorimeter" under the
"Ports (COM & LPT)" section.
2) A system error occured: re-start software and re-connect the cable.
Problem
The colour displayed on the screen differs from the colour of the sample.
Solutions
This is not a malfunction. The measured colour is displayed on the monitor as a guide only. Differences are
common and it is very likely that the measured colour will appear to be different from the colour of the
sample. This is due to several factors (such as the ambient light, monitor calibration, gamma settings) which
must be controlled and fine tuned in order for the colours to match. Contact Eoptis to check how your PC can
be tuned to improve matching.
Problem
The measured colour data are obviously incorrect.
