Installation and Operating Instructions

Bulletin PC-DW-WIFI

The Series DW-WIFI Wireless Wi-Fi Data Logger measures and

records up to 1,000,000 temperature and/or humidity readings and
shares the data with any PC or server on the same Wi-Fi network.
Software settings allow the user to set the high and low alarms, the
sampling rate, and the temperature scale. If the Wi-Fi connection is lost,
the sensor will continue to store any records until it can regain
communication with the network. Stored data can be viewed at any time
after the communications have been restored. Each data logger includes
a wall bracket that allows the data logger to be mounted to any wall or
flat surface.

SOFTWARE INSTALLATION/LOGGER SET-UP

NOTICE

Upon start-up, a reading may be displayed on the LCD; however, the
product set-up must be completed in order to connect to a Wi-Fi network.

logging software for this series, which is available on our website,
http://www.dwyer-inst.com/DW-USBSoftware.

2. After the software is installed, plug the data logger into the PC’s USB
port using the supplied cable and open the software.

3. Click on the “Set-Up Sensor” button.

The logger will arrive partially charged, but for maximum
performance, charge it for 24 hours before the first use.
