HOBO® 4-Channel Analog Data Logger (UX120-006M) Manual

17384-C

The HOBO 4-Channel Analog data logger has 16-bit resolution and can record up to 1.9 million

measurements or events. The four external channels accept a variety of sensors, including

temperature and split-core AC current sensors as well as 4-20 mA and voltage input cables (sold

separately). Using HOBOware®, you can easily configure an alarm to trip when the sensor

reading rises above or falls below a measurement that you specify. Or, you can set up burst

logging in which the logger records data at a different interval during certain conditions. The

logger can also calculate minimum, maximum, average, and standard deviation statistics. This

easy-to-use data logger has a built-in LCD screen to check current readings and to monitor

logging status, battery use, and memory consumption in between readouts.

HOBO 4-Channel Analog Data Logger (UX120-006M) Manual Battery Information The logger requires two user-replaceable AAA 1.5 V alkaline or optional lithium batteries for operation at the extreme ends of the logger operating range. Expected battery life varies based on the ambient temperature where the logger is deployed, the logging or sampling interval, frequency of offloading to the computer, number of channels that are active, if burst or statistics logging modes are active, and battery performance.
