Failure to do so could result in personal injury or damage to the equipment. The SMART Spectro should not be stored or used in a wet or corrosive environment. Care should be taken to prevent water or reagent chemicals from wet spectrophotometer tubes from entering the SMART Spectro chamber.

Sensitivity: Sensitivity is the resolution based on how this term is used in LaMotte catalogs. This term is not listed in any of the references. Sometimes it is used for detection limit. It is a confusing term and should be avoided.
EPA COMPLIANCE The SMART Spectro is an EPA-Accepted instrument. EPA-Accepted means that the instrument meets the requirements for instrumentation as found in test procedures that are approved for the National Primary Drinking Water Regulations (NPDWR) or National Pollutant Discharge Elimination System (NPDES) compliance monitoring programs.
For dissolved oxygen studies, or for tests requiring small sample sizes, a Water Sampler (LaMotte Code 1060) will serve as a subsurface or in-depth sampler. This weighted device is lowered to the sampling depth and allowed to rest at...
A Snap-Plunger Water Sampler (LaMotte Code 1077) is another “in-depth” sampling device which is designed to collect large samples which can be used for a multitude of tests. Basically, this collection apparatus is a hollow cylinder with a spring loaded plunger attached to each end.
Most test substances in water are colorless and undetectable to the human eye. To test for their presence we must find a way to “see” them. The LaMotte SMART Spectro can be used to measure any test substance that is itself colored or can be reacted to produce a color.
Handle the tubes carefully, making sure the bottom half of the tube is not handled. LaMotte Company makes every effort to provide high quality spectrophoto- meter tubes. However, wall thicknesses and diameter of tubes may still vary slightly.
Absorbance or %T, and finding the corresponding concentration from the curve. The linear range of the reagent system can be determined and this information can be used to input a User Test into the SMART Spectro (see EDIT USER TESTS, page 33).

The procedure can be repeated with larger and larger “spikes.” If the determined concentrations do not equal the concentration of the sample plus that added with the “spike”, then an interference may exist. SMART SPECTRO SPECTROPHOTOMETER 05.04...
0.3 + 0.5 = 0.8 ppm iron. (Note: any error due to the increased volume from the “spike” is negligible). LaMotte offers a line of calibration standards which can be used to generate calibration curves and perform standard additions. SAMPLE DILUTION TECHNIQUES &...
INTERFERENCES LaMotte reagent systems are designed to minimize most common interferences. Each individual test instruction discusses interferences unique to that test. Be aware of possible interferences in the water being tested. The reagent systems also contain buffers to adjust the water sample to the ideal pH for the reaction.
The test library consists of 100 LaMotte tests (not all 100 may be available at present) and 25 “User Tests”. The spectrophotometer is also capable of running %T/Absorbance tests over the entire wavelength range of 350 - 1000 nm.

GENERAL OPERATING PROCEDURES The operation of the SMART Spectro is controlled by a microprocessor. The microprocessor is programmed with menu driven software. A menu is a list of choices. This allows a selection of various tasks for the spectrophotometer to perform, such as, scan blank, scan sample, and edit test sequences.
This allows a rapid exit from MAIN MENU EXIT an inner menu to the by repeatedly pushing the button. Pushing at any time will turn the spectrophotometer off. SMART SPECTRO SPECTROPHOTOMETER 05.04...
The Calibrate Wavelength (CALIBRATE WL) mode is used to establish or re-establish the accuracy of the wavelength selection process. Normally, the Calibrate Wavelength procedure should be run after the SMART Spectro is turned ON and allowed to warm up for 15 minutes or if operating conditions (temperature, humidity, etc.) change significantly.
Main Menu. PROGRAMMED TESTS INTRODUCTION The PROGRAMMED TESTS mode is used to run all LaMotte pre-programmed tests and USER TESTS. This is also where USER TESTS and SEQUENCES are set-up and edited. Press ON to turn on the SMART Spectro.
SEQUENCE 1, SEQUENCE 2, and SEQUENCE 3 are alterable sequences. They may be edited using the EDIT function mode. Any of the LaMotte pre-programmed tests or User Tests may be placed in these sequences in whatever testing order that is preferred. Some examples of typical sequences are given below.
The following are some step by step examples of how to run tests from the PROGRAMMED TESTS menu. These test procedures are designed to be used with LaMotte SMART Spectro reagent systems. TESTING WITH THE LaMOTTE PROGRAMMED TESTS Scroll to ALL TESTS with the t button in the PROGRAMMED TESTS PROGRAMMED TESTS menu.

PC LINK The SMART Spectro may be interfaced with any Windows-based program by using the LaMotte SMARTLink2 Program and Interface Cable (Code 1912-3 [3.5 disk] or 1912-CD [compact disk]). The program stores customer information and test data in a database. It can be used to download data stored in the SMART Spectro datalogger for each test site.
BATTERY OPERATION The SMART Spectro can be run using battery power. The battery pack consists of a rechargeable Ni-metal hydride battery pack. The battery pack is not included in the standard meter package and must be purchased as an accessory (Code 2000-BP).
With the meter power ON check the rear lamp access panel to see if any light can be observed through the vents. If the lamp is not ON please contact LaMotte Technical Services Department by phone at 800-344-3100 or 410-778-3100, fax 410-778-6394, or e-mail LaMotte.com for assistance.
BATTERY (optional) If the symbol BAT appears in the upper left corner of the display when using the battery pack, the battery needs to be charged. The SMART Spectro will turn off if the battery power becomes too low. ERROR 1 TROUBLE WITH FILTER There is a problem with filter positioning.
The power supply has an internal switch that handles both 110V and 220V input. STRAY LIGHT The SMART Spectro should have no problems with stray light. Make sure that the sample compartment lid is always fully closed. ACCIDENTAL LOSS OF POWER...
