TURN METER ON
Press the
button to power the meter on; the display will show annunciators, followed by
the current selection. It will then display the last reading.
RINSE & FILL CELL WITH SAMPLE
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,
fi
ll
CELL
to capacity with
the water sample. Tilt meter to discard about 0.2mL water to leave room for liquid reagent.
SELECT GROUP & MENU
Press and re–press the
button to
Select Group
. Press and re–press the
button to
select the test parameter
(see chart on page 6–7).
ADD DROPS
Using the selected bottle of reagent, add the required drops (see chart on page 6–7) and
cover the
CELL
with the
CELL
COVER.
Precaution: Ensure that the bottle is straight when
dispensing drops.
ZERO METER
*
Press the
button. The cursor will move across the display followed by
0.00 PPM
. This will
indicate that the sample is ready for testing.
DIP STRIP & PRESS READ
Using the required strip
(see chart on page 6–7),
dip strip into the
CELL
, and immediately press
to initiate a 20 second countdown. Move the strip using a gentle back and forth motion
(approx. 2 strokes/sec).
Remove and discard the strip after “1” on the display disappears
.
*
The meter will automatically start to count up. The count up time will vary for each parameter. At
the end, the cursor will move across the display while the meter prepares to measure the sample.
Record the value displayed for the respective parameter. This value is automatically stored in its
MENU
and if using the eXact iDip
®
app, the result will be saved in the app’s
‘RESULTS’.
After
testing, rinse
CELL
immediately and clean with the brush. After Sul
fi
de testing: rinse
CELL
with
Distilled White Vinegar, 0.1N HCl, or Muriatic Acid and clean with brush
.

(SPECIAL NOTES)
1
Aluminum
—
A.
First, clean the
CELL
with 0.1N HCl, Distilled Vinegar (5%), or Muriatic Acid (diluted
1:40 with H2O) before testing.
B.
If running multiple tests in a row, using the same water sample, the
CELL
does not have to be rinsed or cleaned with acid between each test. It is recommended that the
CELL
be rinsed 3 times with the sample water.
2
Ammonia
— The calibration of the meter is based on a water temperature between 14°C (57°F) and
28°C (82°F). If temperature is below 14°C (57°F), your final Ammonia value may read low.
3
Sul
fi
de
—
A.
For results as Hydrogen Sulfide (H2S), multiply the resulting value by 1.06.
B.
The
calibration of the meter is based on the water sample temperature above 20°C (68°F). If the water
sample is below 20°C (68°F), the strip
has to dip in the sample for an additional 10 seconds
.
Follow the steps to
‘SELECT CUSTOMER’

‘CONNECT DEVICE VIA BLUETOOTH’
before
proceeding (see page 12).
