Thank you for purchasing a HOBO data logger. With 
proper care, it will give you years of accurate and reliable 
measurements. 
The HOBO U10-003 is a two-channel 
Temperature/Relative Humidity Data Logger with 10-bit 
resolution and capacity for 52,000 measurements. The 
logger uses a direct USB interface for launching and data 
readout by a computer.  
HOBOware

Connecting the logger 
The U-Series logger requires an Onset-supplied USB interface cable to 
connect to the computer. If possible, avoid connecting at temperatures 
below 0°C (32°F)
 
or above 50°C (122°F). 
1.  Plug the large end of the USB interface cable into a USB port on the 
computer.  
2.  Plug the small end of the USB interface cable into the side of the logger 
as shown in the following diagram. 
3.  Load and use logger software to operate the logger (see software 
manual). 
 
If the logger has never been connected to the computer before, it may take 
a few seconds for the new hardware to be detected 
Important: If you configure the logger to start with a trigger start, be 
sure to press and hold down the button on the front of the logger for at 
least three seconds when you want to begin logging. When you release 
the button, the light on the side of the logger will flash rapidly to 
indicate that logging has begun. 
You can read out the logger while it continues to log, stop it manually with 
the software, or let it record data until the memory is full.  
Refer to the software user’s guide for complete details on launching, 
reading out, and viewing data from the logger. 
Sample and event logging 
The logger can record two types of data: samples and events. Samples are 
the sensor measurements recorded at each logging interval (for example, 
the temperature every minute). Events are independent occurrences 
triggered by logger activity. Examples of events recorded asynchronously 
during deployment include: when the logger is connected to the host, when 
the battery is low, end of a datafile once the logger is stopped, and button 
pushes. 
Press the button on the front of the logger for one second to record an 
event. Both a “button down” and a “button up” event will be recorded. This 
is useful if you want to mark the datafile at a particular point.  
The logger stores 64K of data, and can record up to 52,000 samples.
