

Thank you for buying the HOBO® Event data logger. With proper care it will give you years of accurate and reliable
service. The HOBO Event is compatible with the HOBO Shuttle, allowing for convenient retrieval of field data.
Specifications:
Event type: Relay contact openings
Minimum event interval: 1/2 second
Operating temperature (logger): -20°C to +70°C (-4°F to +158°F)
Time accuracy: ±100 ppm at +20°C, full dependence shown in Plot A
Capacity: 8000 events (note that the 8000 events require 32K of memory in the HOBO
Shuttle to fully offload.)
Size/weight: 4.25" x 3.50" x 1.75"/ 3.3 oz.
Battery: CR-2032 (lithium); provides one year of continuous use
Storage temperature: -40°C to +75°C (-40°F to +167°F)
Case: Weatherproof enclosure (avoid placing in direct sunlight)
Relative humidity range (when case is open): 0 to 95%, non-condensing
Connecting the communications cable and Launching
A Starter Kit, which includes an interface cable and software, is required to operate your
logger. Connect the interface cable into the 3.5 mm jack (Diagram A) on the logger and into a working
serial port of your computer. Install and start the logger’s software. Select Launch... under Logger on
the menu bar and the launch dialog box will appear. Note: The act of connecting or disconnecting the
logger's plugs while logger is recording may itself be recorded as an event. For a complete explanation
on installing the software and launching your logger, please refer to the software manual or the
software’s on-line help.
External contact opening
The HOBO Event data logger is intended to operate with a Normally Open contact. It records only the
closure-opening following a contact closure, When the contact is closed, the battery drains about 5
times faster than normal. Consequently Normally Closed contacts are not recommended. The contact
needs to be connected to the cable which plugs into the 2.5 mm jack (Diagram A). In applications
where both actions are important, a HOBO® State data logger should be used. Note: The red wire is
not used.
Connecting to a tipping-bucket rain gauge
The black and white input wires (cable to 2.5 mm jack) of the HOBO Event can be connected directly to
the relay output of most tipping-bucket rain gauges (polarity of input connection does not matter). The
red wire is not used. If your gauge came with a counter display and battery, these should be disconnected,
and the HOBO Event connected instead. When connecting and disconnecting an active HOBO Event, be
careful not to touch the input wires together as this will record an event.
Operation indication
The HOBO Event data logger has a red LED (Light Emitting Diode) (Diagram A) that blinks every two
seconds while it's logging. The LED light also blinks four times rapidly as it stores an event.
Lockout after event
The HOBO Event data logger has a feature that causes it to ignore events for a programmable period after
an event is recorded. The lockout time can be set for as short as one second to as long as nine hours.
When the HOBO Event data logger is being used with a rain gauge, we recommend setting the lockout to
one second to eliminate switch bounce.
Readout
Reconnect the HOBO data logger to the interface cable, start the software, select Readout under Logger on the menu
bar and the data will be displayed. For a complete explanation on reading out your logger, please refer to the software
manual.
Changing the battery
Open the case by unsnapping the latch and lifting the lid. Unplug the 2.5 mm sensor cable. Hold the case upside down
by the bottom and firmly tap the open case into the palm of your hand until the circuit board dislodges. Do not hold the
case by the top or you may snap the lid off! Remove the circuit board from its cover and then remove the battery by
carefully pushing it out with a small, blunt instrument. Be sure to install the battery with its printed side away from
the HOBO’s circuit board (Diagram B). The logger’s light will blink three times after the battery has been installed.
Keep the inside of the case dry
With the case closed and latched, the HOBO Event data logger is weatherproof. The electronics can be permanently
damaged by corrosion from moisture, so protect them from rain and condensation. Should the electronics get wet, remove
the battery immediately and dry the board completely with a hair dryer before reinstalling the battery. The
moisture-absorbing desiccant pack inside the case should be replaced when the battery is changed.
