About Your eXact®Micro 7+ Instrument
In order to save power, the meter is designed to turn off after 3 minutes (timed from the last button pressed).
Should the meter turn off in the middle of a test, the last stored zero in the meter will remain valid when the
meter is turned on again. Also, the test result is stored in memory for easy retrieval.
The eXact
®
Micro 7+ meter is controlled by three buttons:
1. ZERO/ON:KHQ¿UVWSUHVVHGWKLVEXWWRQWXUQVWKHPHWHURQ:KHQWKHPHWHULVRQDQGWKLVEXWWRQLV
pressed, it zeroes the sample in the cell. Once the meter is zeroed, this zero value applies to all parameters
and is stored and retained even when meter turns off. However, it is recommended that each new water
sample analyzed is zeroed before testing, to maximize sensitivity and accuracy.
2. MENU: With each press, the MENU button advances through the tests in the following sequence: CL1,
PH2, BR3, AL4, CA5, CU6, TR7, HR8. Each test menu can store up to 20 results. To retrieve the stored
results, go to the desired test using the MENU key. When the desired test is displayed, press and hold
down the MENU key. Continue holding down the MENU key to scroll the stored results for that test, starting
with the most recent result. The meter will display, from memory, the last 20 readings in sequence beginning
with -20, which is the latest result, followed by -19, which is the 2
nd
ODWHVWUHVXOWHWFDQG¿QDOO\ZKLFKLV
the oldest result retained. Only the last 20 readings are stored in each menu. This meter is able to store 160
results in memory (20 in each menu).
3. READ: When pressed once, this button starts the timer for the parameter being tested. When pressed a
second time the meter exits the timer and immediately prepares to colorimetrically measure the sample, and
simultaneously stores the measurement in memory.
If the parameter being measured is below or above the detection range, the display will show “LO” (Under
Range) or “HI´2YHU5DQJHUHVSHFWLYHO\7KLVIHDWXUHLVPHQXVSHFL¿FDQGGRHVQRWDSSO\WRDOOSDUDPHWHUV

photo cell, and the software as written into the meter. This is why the meter comes with a 2-Year
Warranty.
NOTE: Test algorithms in the new version of photometer (serial numbers above 5000) give
accurate results in fresh and salt water.
Compliance VHULÀFDWLRQIRU)UHHDQG7RWDO&KORULQH7HVWLQJ
This DPD test system is accepted by most health departments because this test is USEPA (DIN
Standard 38 408 G4, ISO 7393/2) accepted for testing requirements for Free and Total Chlorine. The
Micro 7+ meter uses a wavelength of 525nm; and the compliance requirement is that the colorimeter
wavelength is between 490 and 530nm. The eXact
®
Strip Micro CL (DPD-1) uses the same reagents
and proportions, and the resulting solution pH is maintained between 6.2 and 6.5 as VSHFL¿HGby
AWWA (American Water Works Association) method 4500-Cl G. It should be understood that the
USEPA does not "approve" commercial DPD delivery systems such as reagent powder pillows, tablets,
dispensers, or eXact
®
Strip DPD delivery devices. The eXact
®
Strip Micro CL (DPD-1) for Free
Chlorine, and the eXact
®
Strip Micro CL (DPD-3) or the eXact
®
Strip Micro CL (DPD-4) for Total
Chlorine meet your reportable testing requirements because the eXact
®
Strip Micro CL delivers the
same chemicals in identical proportions (see table below); therefore, the system is compliant. Likewise,
AWWA proportions are followed as required for Total Chlorine measurements using Potassium Iodide.

a test is completed. Do not use solvents, such as acetone, to clean the cell. When the CELL becomes
stained or cloudy from repeated testing, or when the meter does not blank when you press the ZERO/ON
button, the cell needs to be cleaned. Clean as follows)LOOFHOOZLWKFOHDQZDWHUDQGPRYHWKHCell
cleaning brush up-and-down and back-and-forth along the walls of the cell. Afterwards, rinse the cell and
the meter is ready for use again. Cleaning the cell regularly is especially recommended after you run a
test that is using turbidity or precipitation chemistry for analysis (Calcium Hardness and Cyanuric Acid).

If your required procedure is not listed in this manual, please see the back page for our contact information.
NOTE: Because most of our products are test strips or use reagents that have little or no hazard in the quantity sold, MSDS sheets are not
supplied with the test. The exceptions are the Manganese (486606) test, which comes with 2 strips and one liquid reagent (PAN); Fluoride
(486643) test, which is a liquid reagent (SPADNS), and Iron (481623) test, which is a powder reagent. Hydrazine (486649) uses a liquid and strip.
To ensure optimal performance, store your eXact®kit in a cool, dry place away from excess heat (below
100°F / 38°C), moisture, and oxidizers such as Chlorine and Bromine.

NOTE : La plupart de nos produits sont des bandes d’analyses et des réactifs contenant peu ou pas de risque, vu la quantité
vendue. Les fiches techniques santé-sécurité (pour matières dangereuses) ne sont donc pas fournies avec. Les tests de manganèse
(486606), viennent avec 2 bandes et un réactif liquide (NPA) et le fluorure (486643) qui utilise un réactif liquide (SPADNS) et le test
du fer (481623) qui utilise un réactif en poudre et l'Hydrazine (486649) qui utilise une languette et un liquide, sont des exceptions.
Pour maximiser la performance, rangez votre trousse eXact® dans un endroit frais, sec, loin de toute
chaleur excessive (sous 100°F / 38°C), de moisissure ou d’oxydants, tels que le chlore et le brome.
