Manganese 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.
FILL METER WITH SAMPLE
3
Rinse the CELL at least 3 times with the water sample you will be testing - rinsing minimizes
the potential for cross-contamination from a previous test. Finally, fill cell to capacity (4ml)
with the water sample.
ZERO METER
4
Press the ZERO/ON button. The cursor will move across the display, followed by 100 %T.
Sample is ready for testing.
DIP STRIP -
(read carefully and follow procedure closely)
5
Dip the Mn Strip #1, Part No. 481020-1 into the CELL and 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 (ignore this result). Next, Dip
the Mn Strip #2, Part No. 481020-2 into the CELL and immediately press READ. This starts a
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 (CAUTION: discard this strip in
regular trash that is inaccessible to children and pets). The cursor will move across the
display, informing you that it is about to measure the sample (ignore this result again).
ADD REAGENT, CAP, MIX, AND WAIT 2 MINUTES
6
Add three (3) drops of PAN Reagent, Part No. 486606-R to the cell, cap, and mix sample briefly
by pressing one finger over the cap to keep it in place and rotate meter upside-down twice. Wait
for two (2) minutes, then press READ. This will start a final 20 SECOND countdown timer.
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
7
Find the "TR" result in the table below to determine the Manganese concentration in ppm (parts
per million). (Example: a "TR" result of 65.3 (use only the 65 for the chart) equals a Manganese
value of 0.04 ppm). Record result. After testing is completed, rinse cell immediately.
Manganese Table
Manganese results require the table below. Follow eXact
Mn Strip #1, Part No. 481020-1, Mn Strip #2, Part No. 481020-2, and PAN Reagent, Part Number 486606-R.
Mn Strip #1, Part No. 481020-1, Mn Strip #2, Part No. 481020-2, & PAN Reagent, Part No. 486606-R - for 4mL Samples
