Introduction
1-1 Battery Installation
The V-2000 requires 4 AA alkaline or lithium batteries. With alkaline batteries, the expected life
is 2,500 hours of operation. With lithium batteries, the expected life is 10,000 hours of operation.
The V-2000 has a battery saving auto-shutoff feature that turns the instrument off after 20
minutes of non-use. Remove batteries when photometer is not in use.
To install batteries, carefully loosen the 2 captive screws on the battery cover (back of
instrument). Remove the cover, and insert the batteries with the correct orientation as illustrated
in the battery compartment. Replace the battery cover and replace the captive screws.
1-2 Sample Cell Adapters
The V-2000 comes with 2 sample cell adapters: 13 mm adapter for Vacu-vials; 16 mm adapter
for COD Vials. The adapters ensure correct alignment of the ampoule or vial being used. If the
ampoule or vial is not aligned correctly (i.e. wrong adapter or no adapter is used), measurement
errors will occur.
To insert an adapter, the male tabs on the adapter (left and right sides) should be matched up
with the alignment slots to the left and right of the sample cell compartment. Insert the adapter
with the correct alignment and push down firmly until it snaps into place.
Important Note: Above the sample cell compartment, the instrument says
“cuvette adapter = lock-unlock <”. Disregard this message!
There is no lock, unlock feature to the current cell adapters.
They go straight in and out. DO NOT attempt to turn the
adapter from left to right when inserting it or removing it.

Setup and Measurement Procedures
3-1 General Operating Instructions
The following guidelines can be considered general operating instructions for the V-2000
photometer. More parameter specific information is provided in the kit instructions supplied with
each Vacu-vial or COD test kit.
# The V-2000 must be zeroed prior to each series of measurements. Additionally, if the
ampoule/vial adapter has been removed or comes loose during operation, the V-2000
should be re-zeroed.
# For best results, always cover the ampoule or vial with the light shield prior to zeroing
the instrument, setting a reagent blank value or measuring a sample.
# For COD testing, LED based photometers do not produce accuracy, precision and
sensitivity equivalent to that attainable from spectrophotometers. For NPDES
reporting purposes for COD, a spectrophotometer is the preferred method of
measurement. A full comparison of the range and accuracy claims for COD on the two
different instrument platforms is available from the CHEMetrics Technical Services
Department.
