BATTERY REPLACEMENT
The lithium-ion battery used in this unit should last for many years with
normal use. When it no longer powers the unit long enough to meet testing
requirements it will need to be replaced. Lithium-ion batteries that are properly
charged and stored do not usually lose all capacity; they just have less
capacity after hundreds of charge cycles. This unit uses a custom battery
assembly. The water resistant housing of this meter should not be opened by
the user.

MAINTENANCE
CLEANING
Clean the exterior housing with a damp, lint-free cloth. Do not allow water
to enter the light chamber or any other parts of the meter. To clean the light
chamber and optics area, point a can of compressed air into the light chamber
and blow the pressurized air into the light chamber. Use a cotton swab
dampened with Windex
®
window cleaner to gently swab the interior of the
chamber. Do not use alcohol; it will leave a thin residue over the optics when
dry.
COLORIMETER TUBES AND CHAMBER
Colorimeter tubes and colorimeter chambers which have been scratched
through excessive use should be discarded and replaced with new ones. Dirty
tubes should be cleaned on both the inside and outside. Fingerprints on the
exterior of the tubes can cause excessive light scattering and result in errors.
Handle the tubes carefully, making sure the bottom half of the tube is not
handled.
LaMotte Company makes every effort to provide high quality colorimeter
tubes. However, wall thicknesses and diameter of tubes may still vary slightly.
This may lead to slight variations in results (e.g. if a tube is turned while in the
sample chamber, the reading will likely change slightly). To eliminate this error
put the tubes into the sample chamber with the same orientation every time.
The tubes that are included with the colorimeter have an index mark to facilitate
this. If possible, use the same tube to SCAN BLANK and SCAN SAMPLE.
