The HOBO 4‐Channel Pulse Input data logger records electronic pulses and mechanical or
electrical contact closures from external sensing devices. Using HOBOware®, you can easily
configure each of its four channels to monitor and record pulse, event, state, or runtime data in
a wide variety of applications, including tracking building energy consumption, monitoring
mechanical equipment, and recording water and gas flow rates. Plus, when combined with the
E50B2 Energy & Power Meter (T‐VER‐E50B2), this logger provides extensive power and energy
monitoring capabilities. There are two models of the HOBO 4‐Channel Pulse Input data logger:
the UX120‐017 stores more than 500,000 measurements while the UX120‐017M holds more
than 4,000,000 measurements.

Terminal Blocks: There are 4 terminal blocks included with the logger to plug into the inputs for connecting devices. Test Button: Press this button to activate the Activity Lights for 10 minutes to test for contact resistance or voltage signal in any of the four input channels (see the LED table). Mounting Holes: There are four mounting holes, two on each side, that you can use to mount the logger to a surface (see Mounting the Logger). USB Port: This is the port used to connect the logger to the computer or the HOBO U‐Shuttle via USB cable (see Setting up the Logger and Reading Out the Logger). Plot A: Time Accuracy Setting Up the Logger Use HOBOware Pro to set up the logger, including selecting the Logger Components and Operation start and stop logging options, configuring the input channels for specific sensor types, and entering scaling factors. It may be Start/Stop Button LEDs helpful to set up the logger with a Delayed Start or a Button Start first and then bring it to the location where you will mount it to connect the external sensors/devices and test the connections before logging begins. 1. Connect the logger and open the Launch window. To connect the logger to a computer, plug the small end of the USB Port USB cable into the side of the logger and the large end into a USB port on the computer.
