EPA COMPLIANCE
The DC1600 Colorimeter is an EPA-Accepted instrument. EPA-Accepted means that the instrument meets the

Regulations (NPDWR) or National Pollutant Discharge Elimination System (NPDES) compliance monitoring programs.
EPA-Accepted instruments may be used with approved test procedures without additional approval.
REPLACING LIGHT BULB
Turn the meter over, making sure the battery compartment is in the upper left corner (This is important). Remove the four
screws from the bottom of the colorimeter and remove the base. The burned out light bulb is attached to the small
rectangular circuit located just to the right (your right) of the light chamber. Remove the two screws that connect the
circuit and SAVE THE BURNED OUT LIGHT BULB. The light bulb must be returned to LaMotte Company for
replacement. Make sure the two washers are still in place. Remove the screw in the upper left corner of the colorimeter and
detach the replacement circuit. Replace that screw. When fastening the fresh bulb in place, be sure both washers are
aligned. Align the base to the meter and replace the four original screws.
NOTE: If the re place ment bulb is sig nif i cantly dif fer ent from the orig i nal bulb, the “Set Blank” con trol may not have
enough range; if so, please call our tech ni cal sup port peo ple for as sis tance.
REPLACING THE BATTERY
The colorimeter is equipped with a battery check indication, the symbols BAT and ~ on the left hand side of the display,
that will be displayed when the battery needs to be replaced. The meter will still provide valid readings, but the readings
may drift. Eventually the meter will not have enough power to turn on. To replace the battery, remove the panel on the
back of the meter and detach the battery. Replace with a fresh alkaline 1604A type (9V) battery.
Battery polarity (+ & –) must never be reversed, even momentarily. If it is, the instrument will be rendered
INOPERABLE, and must be returned to LaMotte Company for repair. This will be considered a non-warranty repair.
Use appropriate caution when replacing the battery.
