recommended.)
2. The battery icon on the screen will show the battery status. Charge the battery
until the battery indicator is full.

5
SOFTWARE UPDATES
Occasionally, the AQUASPIN meter will require updates and your PC will prompt
you to do these updates by allowing you to “Update Now” or “Remind Me Later”.
If Remind Me Later is chosen, the update prompt will be displayed again in 23
hours. To update the software, open WaterLink Connect 2 on your computer, go
to Settings > Service Settings > Get Updates.
Make sure your AQUASPIN meter is connected and then run the updates. Updates
can take up to 30 minutes and you will want to dedicate that time to doing
the update and nothing else on your computer to allow the update to not be
disrupted.
PC CONNECTION
When the API AQUASPIN meter is connected to a PC via USB cable, the onboard
touchscreen becomes disabled and operation of the meter is performed using the
API AQUASPIN website application. This application can be accessed at: http://
apifishcare.com/aquaspin/ via the API AQUASPIN website application, results from
the meter will show on the computer screen, and can be saved to a customer’s
account and emailed with API product recommendations.
Customers must create an account from the link they receive in their API product
recommendations email for their account creation to be finalized.

FILLING DISKS
When the syringe is placed in the water sample and
the plunger is pulled all the way up, the syringe will hold
more than enough water to adequately fill the disk.
1. Fill the included syringe with the water sample.
Then, locate the fill hole on the disk and slowly,
with even pressure, begin to fill the disk with the
syringe held vertically. The sample water will fill
the chambers between the baffles in a counter-
clockwise order. Each chamber will fill from
the bottom to the top. Sample water should
be added until the sample water in the fourth
chamber fills to the top of the chamber slightly
past the embossed fill line (it is ok to fill slightly past
the fill line).
Correct Fill
(Fill line)
2. DO NOT overfill the disk. If the disk is overfilled,
sample water will flow out of the overflow hole in
the center of the disk. If this happens, be sure to
dry the disk completely before running the test.
Overfilled
(Dry disk before placing in meter)
3. DO NOT underfill the disk. If the disk is under filled,
the reagent chambers will not fill entirely and
results will be inaccurate.
Underfilled
4. Do not introduce air bubbles into the disk. The
reagent chambers will not fill entirely and results
will be inaccurate. As soon as a bubble starts to
form, pull back on the plunger to draw the bubble
out of the disk. Begin the filling process again.
Air
Bubble
5. Wet disks should be dried thoroughly with the
included lint-free wipe. The disk should be handled
on the edges only. The disk should be filled and
used within 10 minutes. They cannot be filled
ahead of time. Refer to Step 4 under the TESTING
section for next steps.

7
GENERAL OPERATING PROCEDURES
DISK HANDLING
The disk should be handled only by the edges. Avoid
touching the top or bottom of the disk. The light passes
through the non-frosted areas of the disk so these areas
must be kept free of smudges and fingerprints. Wet disks
should never be placed in the meter. Wet disks should be
dried with a lint-free cloth before placing them into the
chamber.
The disk is positioned in the chamber by aligning the
D-shaped hole in the center of the disk over the D-shaped
hub in the photometer chamber. The disk should be
placed gently on the hub. There is no need to firmly press
the disk down onto the hub. Universal disk cover should
then be placed over the disk before running the test.
DISK STORAGE
Disks are sensitive to moisture and UV light. Avoid
opening more packs than are needed. Disks have
a limited shelf life and should not be exposed to the
humidity in the air more than necessary.
Do not transport the meter with a disk in the chamber.
Store disks at 70°-80 °F (21°-27 °C).
METER
When a filled disk is placed in the chamber with universal disk cover and the lid
is closed, the meter spins at high speed to distribute the sample to the test wells.
Next the meter slows to maximize the pumping action of the stainless steel mixing
beads as the reagents mix with the sample water. Each reaction is then read at
the proper time and wavelength for that reagent system.
The button located in the lower center of the top of the meter
turns the instrument on and off.
The blue on/off button indicator light indicates the status of the instrument.
Steady blue light – the blue LED will remain steady to indicate that the meter is on
and ready to run a test.
Blinking blue light (three blinks/second) – a test is in progress and the disk is
spinning. Do not open the lid when the disk is spinning.
Care should be taken when closing the lid. Do not slam the lid. Wiring between the
lid and the body of the photometer passes through the hinge. The meter will not
run with the lid open.

SYRINGE
A plastic syringe is used to fill the disks. A precision tip on
the syringe fits into the fill hole on the disk. The syringe tip
should not be removed from the syringe. Syringes should be
cleaned between water samples. Pump air in and out of
the syringe a few times to clear the previous sample, or rinse
the syringe with a small amount of the next water sample
before filling it with the next sample.

12
REAGENT DISK
The API AQUASPIN uses a disk reagent system. The dried reagents
are packaged in single test amounts in a sealed, polystyrene disk.
Stainless steel mixing beads in the reaction chambers mix the
sample water and the dried reagents. Tests for all factors in the
series are performed at one time. It is not possible to isolate the
well for a single factor and perform a test for one test factor only.
Disks should not be filled in the meter chamber.
UNIVERSAL DISK COVER
The black Universal Disk Cover (1719) is placed over the
disk in the photometer chamber to reduce interference
from stray light. The disk cover is positioned over the disk by
aligning the D-shaped hole in the center of the disk over the
D-shaped hub in the photometer chamber. The disk cover
should be placed gently on the hub. There is no need to
firmly press the disk cover down onto the hub. The test will be
aborted if the disk cover is not used.
METER CHECK DISK
The Meter Check Disk (AP-1705) serves two purposes:
¬When the Meter Check Disk (MCD) is run as an option from the Disk Series
menu, the values on the display are compared to the values on the chart
on the Meter Check Disk package to determine whether the meter is
reporting results in the expected ranges.
¬If the Meter Check Disk is inserted in the meter and Rotary Calibration
is chosen from the Settings Menu, the alignment of the hub and disk is
evaluated. The results are analyzed and reported as Pass or Fail.
For use of the Meter Check Disk see page 15.
USB CABLE
A USB cable connects the API AQUASPIN to a PC. When used with the AC Power
Adapter, it connects the meter to an AC outlet.
WARNING: only use the wall adapter that is supplied with the kit. Make no
substitutions.
BATTERY
A fully charged battery will last for approximately 150 tests under average
conditions. The battery life will vary based on usage patterns. The meter should
be turned off after testing to prolong the battery life. The standard life cycle of a
lithium ion battery is 500 cycles. The battery will fully charge in approximately 10-12
hours. The battery is designed to be charged overnight and should be charged
indoors only. The battery is rated at 12 V and 8.1 AH capacity. Power the meter
from the battery pack or from AC power. The USB cable and AC adapter are used
to plug the meter into an AC outlet. WARNING: only use the AC adapter supplied
with this equipment. Do not substitute.
The battery charge status is indicated by the battery icon on the display. The
battery icon will indicate when the battery charge is full, partial, low, empty or
charging. The empty battery icon will flash to indicate that meter should be
connected to AC power source. If the meter continues to be used at low battery

13
power without connecting it an AC power source, the meter will go into an
auto-shutdown mode. In this mode the meter will be locked until the meter is
connected to an AC source and the battery is charged to a sufficient voltage.

CONVERSIONS
Ammonia (NH3)
Ammonia in water occurs in two forms: toxic unionized ammonia (NH3) and the
relatively non-toxic ionized form, ammonium ion (NH4+). This test method measures
both forms as ammonia (NH3) to give the total ammonia
concentration in water.
The actual proportion of each compound depends on temperature,
salinity, and
pH. A greater concentration of unionized ammonia is present when the pH value
and salinity increase.
1. Consult the table to find the percentage that corresponds to the temperature,
pH, and salinity of the sample.
2. To express the test result as ppm Unionized Ammonia (NH3), multiply the Total
Ammonia test result by the percentage from the table.
3. To express the test result as ppm Ionized Ammonia (NH4+), subtract the
Unionized Ammonia determined in step 2 from the Total Ammonia.

FOR EXAMPLE:
A fresh water sample at 20°C has a pH of 8.5 and the test result is 1.0 ppm as Total
Ammonia.
1. The percentage from the table is 11.18% (or 0.1118).
2. 1 ppm Total Ammonia x 0.1118 = 0.1118 ppm Unionized Ammonia
3. Total Ammonia 1.0000 ppm
Unionized Ammonia _0.1118 ppm
Ionized Ammonia = 0.8882 ppm
To convert Ammonia (NH3) to Ammonia-Nitrogen (NH3-N) multiply by 0.823
To convert Nitrite (NO2) to Nitrite-Nitrogen (NO2-N) multiply by 0.304
To convert Nitrate (NO3) to Nitrate-Nitrogen (NO3-N) multiply by 0.226
