Series DW-USB Compact USB Data Logger
Specifications and Operating Instructions
Bulletin E-90-CDW
The Series DW-USB Compact USB Data Logger
allow users to
monitor temperature, humidity, dew point, voltage, current, or carbon
monoxide. The user can select the sampling rate, start time, high/low
alarm settings, and temperature unit parameters with the free
downloadable Windows
®
-based application. Stored data is downloaded
by plugging the module into a PC’s USB port. Alarm status and low
battery is indicated via built-in flashing LED’s. When the protective cap
is fitted, the data logger resists moisture to IP67 standards.
