Configuring the Data Logger for the VOC Monitor using HOBOware Software
Note: HOBOware software provides a configuration file for the monitor. The table below lists the recommended configuration
values that this file contains. For information on loading configuration files, refer to the software documentation.

*Loop power of 22 mA can be provided by the FlexSmart Analog Module and H22 (or Analog Sensor Port/Module and U30 or
RX3000). Lamp and electronics require 65 mA. Note: Providing continuous warm-up excitation power will accelerate data logger
battery depletion. Therefore, we recommend using the appropriate Onset AC power adapter to power the logger.
