For Pool and Spa Salt Systems

Salt/Chloride (as NaCl) Test Procedure

TR7
TURN METER ON
1
Press the ZERO/ON button to power the meter on; the display will show all annunciators,
then the current MENU selection, followed by the last reading.
SELECT TEST: TR7
2
Press and re-press the MENU button until the display shows the parameter TR7.
PREPARE THE CELL
3
Using deionized or distilled water, rinse the CELL at least 3 times to minimize potential cross
ADD THE SAMPLE
4
Use the small pipet provided to add 0.2ml of the sample to the water in the cell. This is a
1 to 20 dilution of the pool water that is required to perform this test. NOTE: If you are using the
more accurate dilution procedure with the Dilution Kit (487200) or Mini Dilution Kit II (487202),
follow the procedure as provided with those kits.
ZERO METER*
5
Press the ZERO/ON button. The cursor will move across the display, followed by 100 %T.
Meter is ready for testing.
DIP STRIP
6
Dip the eXact
press READ. This starts the 20 SECOND countdown timer. During this time move the strip
in a gentle back and forth motion. Remove and discard the strip after "1" on the display
disappears*. The cursor will move across the display while the meter prepares to measure
the sample. Record result displayed (this result is automatically stored in TR7).
USE TABLE
7
Find the "TR7" result in the table below to determine the Sodium Chloride concentration in ppm
(parts per million). (Example: a "TR7" result of 65.3 (use only the 65 for the chart) equals a Sodium
Chloride value of 1400 ppm). Record result. After testing is completed, rinse cell immediately.
Sodium Chloride results require the table below. Follow eXact
using eXact Strip Micro CH, Part No. 481657-II. NOTE: To convert the NaCl value to Chloride (Cl
®
multiply the value from the chart below by 0.6. (Example: 1380ppm NaCl = 828ppm Cl
