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.
ADD THE SAMPLE
3
A 1 to 40 dilution of the pool water is required to perform this test. Follow the directions in the Mini
Dilution Kit (Part No. 487201, included) to perform the dilution. Rinse the CELL 3 times with the
diluted sample, and then fill the CELL to capacity (4ml) with the diluted sample.
ZERO METER
4
Press the ZERO/ON button. The cursor will move across the display, followed by 100 %T.
Meter is ready for testing.
DIP STRIP
5
Dip the eXact
immediately 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 when the
time displays 1. The cursor will move across the display, informing you that it is about to
measure the sample. Record result displayed (this result is automatically stored in TR7).
USE TABLE
6
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 2760 ppm). Record result. After testing is completed, rinse cell immediately.
Sodium Chloride results require the table below. Follow eXact
Procedure (above) using eXact
Chloride (Cl ), multiply the value from the chart below by 0.6. (Example: 4600ppm NaCl = 2760ppm Cl
