logging. HOBOware™ displays the progress of the launch and warns the user not to unplug the logger
while it is being configured.
NOTE: Launch settings are discussed in depth in “Chapter 2: Working with loggers.” in the
HOBOware™ Users Guide.
11. To disconnect a logger, simply unplug it from the USB cable or the computer.
2.3 Analyzer Initial Operational Tests
After a warm-up period has been allowed for, the sensor should be checked to verify sensitivity to its target
gas.
Material Requirements
™
Span gas containing the target gas in air or nitrogen. It is recommended that the target gas concentration
be 50% of scale at a controlled flow rate of 500 ml/min. For example, a Model DM-200-H

S UniTox™
sensor in the range 0-100ppm would require a test gas of 50ppm H
2
S. For a sensor with a range of 0-
20ppm a test gas of 10ppm is recommended, etc.
a) Connect span gas to the “Span/Zero Inlet Port” and place the 3-way Valve in the “Calibrate” position.
b) Apply the span gas at a controlled flow rate of 500cc/min. Observe that the LCD display increases to a
level of 10% of the span level. I.e. if the sensor range is 0-100ppm and the span gas is 50ppm the reading
should rise to within 10% of 50ppm (45-55ppm).
c) Remove the span gas, place the 3-way valve if the “Sample” position, and observe that the LCD display
increases/decreases to the expected process level.

S gas sensors are calibrated prior to shipment, and should not require significant adjustment on start
up. However, it is recommended that a complete calibration test and adjustment be performed within 24 hours
of installation. Refer to calibration instructions in section 4.0.
2.4 HOBOware™ Operational Test
1. After initial test of Analyzer, if the data logger is not attached to the PC and the HOBOware software is
not running, invoke the HOBO Software and connect the data logger to the PC/Laptop via the USB Cable.
2. When the logger is recognized by HOBOware, the right side of the status bar at the bottom of the
HOBOware window will update to reflect the number of loggers connected. When the logger is
recognized, it is ready for use.
3. Click the Readout icon on the toolbar. Click Stop when HOBOware asks if you want to stop the
logger before reading out.
