Installation and
Placement
WatchDog loggers have the versatility to be located in
any micro-climate for recording weather data. The
sensors and the mini-radiation shield include hardware
for attaching them on a 1” to 1¼” outside diameter
mast (pipe). Use a 5’ - 10’ length of conduit or pipe as
the mast mount. When purchasing and/or cutting the
mast to size, plan on placing 1½’ - 2’ of the mast into
the ground.
For outdoor and greenhouse use, it is required that the
WatchDog logger be placed in a mini-radiation shield
to protect it from solar radiation and other sources of
reflected heat. The radiation shield also protects the
logger from rain. To place the WatchDog into the
radiation shield, unscrew the two finger-nuts and
remove the top of the radiation shield.
Important: External sensor
wires connect to the logger
through an opening at the
bottom of the shield. Secure
the external sensor wires to
the mast just below the
radiation shield with a
plastic tie. This will insure
that the sensor wires do not
become disconnected while
recording.

To launch and/or download data from the logger,
connect the logger to a computer via the data
transmission cable. This cable is included with the
SpecWare software package. The data cable connects
to an available serial port on your personal computer
and the port labeled “computer” on the logger.
The only time you must have the WatchDog connected
to the computer is during the launching and
downloading of the data logger. After the logger has
been launched, and/or downloaded, disconnect the
logger and place it in the environment you wish to
monitor.
Computer
Port
If the computer will not connect with the logger, you
may need to change the battery or change the com port
settings. Refer to the battery replacement section on
page 8 for battery instructions. Refer to the SpecWare
software Manual for complete instructions on
launching and downloading the WatchDog loggers.

Battery
Replacement
Each WatchDog Data Logger is powered by a 3 Volt
CR2032 battery. The battery has a life of 6 months
continuous use and a 2-year shelf life. It is user
replaceable and can be purchased locally. Other battery
numbers that may be substituted for a CR2032 are
BR2032 or DL2032.
To replace the battery:
1. Remove the screw on the back cover of the
WatchDog.
2. Remove the back cover.
3. Slide the battery out of the battery holder.
4. Insert a new CR2032 battery positive side up.
5. Replace WatchDog cover.
6. Tighten back cover screw.
The logger is ready to be relaunched if the LED briefly
illuminates following battery installation. After being
relaunched with the SpecWare Software, the LED light
will resume blinking.
Insert a flat-edged
screwdriver completely
underneath old battery.
Gently lift edge of
battery over casing lip
and slide battery out.
Slide new battery into
battery casing.

Commonly asked questions include:
Q. Why will logger not connect with computer?
A. Data logger needs a new battery or the COM Port
settings need to be changed through SpecWare
software.
Q. Why is logger logging invalid or out-of-range
readings?
A. External temperature sensor is not plugged into the
port.
Q. Can I use the external port of my WatchDog Model
125 or 130 to monitor rainfall?
A. The external port is only set up to be connected to a
temperature sensor (for the 125) or a leaf wetness
sensor (for the 130).
