HOBO® Motor On/Off Data Logger (UX90-004x) Manual
15432-F
The HOBO Motor On/Off data logger records motor on and off conditions by detecting the AC
magnetic fields given off by a rotating motor using its internal sensor. A second external input
can be used to detect a variety of external contact closure type inputs. Using HOBOware®, you
can easily configure the logger for equipment monitoring in a wide variety of applications. This
compact data logger has a built-in LCD screen for checking status, battery usage, and memory
consumption. You can also use the LCD screen to quickly calibrate the logger’s motor sensor
near the motor to be monitored or you can set calibration to preset sensitivity levels with
HOBOware. There are two models of the HOBO Motor On/Off data logger: the UX90-004 has a
memory capacity of 128 KB while the UX90-004M has 512 KB.
