MAINTENANCE
 CLEANING
Clean with a damp, lint-free cloth.
DO NOT ALLOW WATER TO ENTER THE SPECTROPHOTOMETER CHAMBER
OR ANY OTHER PARTS OF THE METER.
 LIGHT BULB
The quartz halogen bulb in the SMART Spectro has an approximate life of 1000
hours. If a test is performed and there is no response and the unit is receiving
adequate power, the light bulb may need to be re-secured or replaced. With the
meter power ON check the rear lamp access panel to see if any light acan be
observed through the vents. If the lamp is not ON it is either loose or burnt out.
To determine if the lamp is loose, remove the vented panel on the back of the
meter. Loosen both thumb screws, noting that the thumb screws do not remove
from the unit completely; they are attached to the removable metal plate. Use a
clean, folded paper towel to gently push the lamp and see if it lights up. If so, it
was merely loose and can be fi rmly pushed into its socket. If the lamp doesn’t
light up, it should be replaced. Contact LaMotte Technical Service at 1-800-344-
3100 ext 2, or eamil [email protected] for a Return Authorization number and
service by LaMotte personnel. Or order LaMotte code# 27290-03 for a 10-watt
replacement lamp and replacement instructions.
 CLOCK BATTERY (RAM BATTERY)
The Smart Spectro date/clock function is powered by its own battery. This
battery should be replaced about every 3 years. If the date or clock function
stops or if you receive the message “Warning RAM Battery Low” you should
replace the RAM battery as follows, or contact the LaMotte Technical Service
Department by phone at 1-800-344-3100, fax 410-778-6394 or email tech@
