OPERATION OF THE SMART SPECTRO
 OVERVIEW
The SMART Spectro is a portable, microprocessor controlled, direct reading,
single beam spectrophotometer. It has a 5 line, 18 character liquid crystal
display for alphabetical and numerical messages. The operation is controlled
with the keypad through menu driven software in response to selections shown
on the display.
The test library consists of over 80 LaMotte tests and 25 “User Tests”. The
spectrophotometer is also capable of running %T/Absorbance tests over the
entire wavelength range of 350 - 1000 nm. The LaMotte tests are precalibrated
for LaMotte reagent systems. The spectrophotometer displays the results of
these tests directly in units of concentration. The 25 “User Tests” may be used
to enter additional calibrations. All of these tests may be arranged in any of 3
sequences. These sequences can be modifi ed a limitless number of times to
meet changing testing needs.
The optics feature a quartz halogen bulb as a light source with a minimum
life expectancy of 1000 hours. The incident white light is dispersed into its
component wavelengths by a 1200 lines/mm ruled grating. The microprocessor
controls the positioning of the grating, automatically positioning the grating to
the correct wavelength for the test that has been selected. The monochromatic
light is passed through the sample cell and is detected by a silicon photodiode.
The SMART Spectro is powered by an AC adapter that automatically recognizes
the input voltage (110/220V) and converts it to the 12V needed to run the
instrument. An optional battery pack is available for use where portability is
important. To save power an automatic shut-off feature can be utilized (Energy
Savings Mode).
A RS-232 serial port on the back of the spectrophotometer, and optional
software, allows the spectrophotometer to be interfaced with a Winows-based
personal computer for real time data acquisition and data storage. This port also
allows an interface with a RS-232 serial printer.
Due to its portability, alternate power sources, and rugged construction, the
SMART Spectro is ideal for lab and fi eld use.
 POWER SOURCE
To use the SMART Spectro with an AC power supply:
1. Plug the Power Supply into the AC Adapter socket on the back of the SMART
Spectro.
2. Connect the Power Cable to the Power Supply and an electrical outlet.
To use the Battery Pack, see page 51.
