NOTICE:
Changes or modifications made to this equipment not expressly approved by
AquaCheck (Pty) Ltd. could void the user's authority to operate the equipment.
Use only AquaCheck (Pty) Ltd approved acces sories.
This device complies with part 15 of the FCC Rules. Operation is subject to the following
two conditions: 1) This device may not cause harmful interference, and 2) This device
must accept any interference received, including interference that may cause undesired
operation
This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This
equipment generates, uses and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the
user is encouraged to try to correct the interference by one or more of the following
measures:
• Reorient or relocate the receiving antenn a.
• Increase the separation between the eq uipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
• Consult the dealer or an experienced radio/T V t ec hnician for help
This device complies with Industry Canada licence-exempt RSS standard(s). Operation
is subject to the following two conditions: (1) this device may not cause interference, and
(2) this device must accept any interference, including interference that may cause
undesired operation of the device.
Under Industry Canada regulations, this radio transmitter may only operate using an
antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry
Canada. To reduce potential radio interference to other users, the antenna type and its
gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not
more than that necessary for successful communication.
This radio transmitter (identify the device by certification number, or model number if
Category II) has been approved by Industry Canada to operate with the antenna types
listed below with the maximum permissible gain and required antenna impedance for
each antenna type indicated. Antenna types not included in this list, having a gain
greater than the maximum gain indicated for that type, are strictly prohibited for use with
this device.

Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils
radio exempts de licence. L'exploitation est autorisée aux deux conditions suivantes : (1)
l'appareil ne doit pas produire de brouillage, et (2) l'appareil doit accepter tout brouillage
radioélectrique subi, même si le brouillage est susceptible d'en compromettre le
fonctionnement.
Conformément à la réglementation d'Industrie Canada, le présent émetteur radio peut
fonctionner avec une antenne d'un type et d'un gain maximal (ou inférieur) approuvé
pour l'émetteur par Industrie Canada. Dans le but de réduire les risques de brouillage
radioélectrique à l'intention des autres utilisateurs, il faut choisir le type d'antenne et son
gain de sorte que la puissance isotrope rayonnée équivalente (p.i.r.e.) ne dépasse pas
l'intensité nécessaire à l'établissement d'une communication satisfaisante.
Le présent émetteur radio (identifier le dispositif par son numéro de certification ou son
numéro de modèle s'il fait partie du matériel de catégorie I) a été approuvé par Industrie
Canada pour fonctionner avec les types d'antenne énumérés ci-dessous et ayant un
gain admissible maximal et l'impédance requise pour chaque type d'antenne. Les types
d'antenne non inclus dans cette liste, ou dont le gain est supérieur au gain maximal
indiqué, sont strictement interdits pour l'exploitation de l'émetteur.

1 Introduction
Capacitance based soil moisture probes have been used for irrigation scheduling
purposes for the past 15 years around the world.
Global market trends have however necessitated a revised point of departure for
affordable and practical irrigation scheduling technology and instruments.
AquaCheck (Pty) Ltd, has recognized the shift in global trends. The AquaCheck
probe was therefore specifically developed to address these needs. Its design and
construction is not only flexible enough to interface with the most advanced irrigation
system, but also has the ability to function as a very basic tool for entry level
irrigators.
Five versions of the AquaCheck II probe are available:
o A BASIC II wireless continuous logging version using a wireless hand-held
logger for data transfer to a PC;
o An ANALOGUE version compatible to third party analogue loggers.
o A SDI-12 version compatible to third party SDI-12 loggers.
o A MODBUS version compatible to third party MODBUS loggers.
o An AquaGREEN probe (SDI-12 or MODBUS) for greenhouse and turf
applications.
Capacitance sensors measure the dielectric constant of the soil by applying a
voltage between two electric plates (sensor rings). The frequency measured by the
rings varies with the dielectric constant, and this is used to calculate the soil
moisture content of the soil. The sensors are typically positioned at various depths
on a column 32mm in diameter. The current AquaCheck probe range offers six
standard length options varying from 200mm to 1200m m. The 400mm typically has
4 sensors and the 1200mm offers 6 sensor depths (see page 10 – configuration).
The column with attached sensors is posit ioned in the probe shaft and is sea led with
a water resistant resin. After assembly, the sensors are individually calibrated or
normalized to set the default air and water counts for each sensor. The probe also
takes a soil temperature reading at each depth. Each sensor has a built-in
temperature variation compensation factor. Readings from each sensor are
therefore corrected for possible inherent electronic temperature v ar iations.
The probe can be set to take readings at variable time intervals but typically a
reading every 30 minutes (on all 6 sensors) would allow f or up to 42 days on-board
storage capacity.
This manual covers the BASIC II wireless version.

1 ACPROBE-R Wireless System Components
Figure 1: Hand-held wireless logger
The ACPROBE-R wireless system consists of the following components:
A. A continuous logging soil moisture probe
B. Hand-held wireless logger unit & CropGraph software
C. Accessories:
a. Charger & Download cable
b. Manual & Installation CD
c. RF Utility Module
d. Installation Kit
The AquaCheck Basic II wireless probe is also offered in a sub-surface
configuration for turf and pasture applications. For this applicat ion the probe head
and shaft are separate units joined by a 0.5m cable. The shaft is equipped with a
hardened top cap, which if viewed from the top, looks like a standard popup
sprinkler head once installed.
The probe head is embedded in a separate sleeve with a screw-on lid allowing
access to the probe head. The lid can be opened and probe head removed to
replace the battery pack. (For more detail on the subs urface version please visit
