4.7.2.1.5. Logging
The Logging box shown in Figure 15 is used to control the log in the Data Logger firmware.
Figure 15. Logging Box
The upper part of this box displays the current number of samples in the log.
The Data Logger firmware constantly takes samples and displays them on the LCD. If logging is enabled, the
samples are also saved in the log. Samples continue to be taken when logging is disabled.
If logging is enabled, the left button says “Stop Logging”, and logging is disabled if this button is clicked.
If logging is disabled, the left button says “Start Logging”, and logging is enabled if this button is clicked.
Note: Logging may also be enabled and disabled with the SW3 button on the MCU card.
The “Erase Log” button deletes all the samples in the log.
4.7.2.1.6. Information
The Information box displays version and identification information.

4.7.2.1.7. Thresholds
The Thresholds box is used to configure alarm thresholds.
A humidity alarm occurs if the humidity is greater than the high humidity threshold or less than the low humidity
threshold. A temperature alarm occurs if the temperature is greater than the high temperature threshold or less
than the low temperature threshold.
The Thresholds box displays the current threshold settings. If a text box is empty, that threshold is not used. If all
text boxes are empty, then no humidity or temperature alarms are generated by the Data Logger firmware.
To set the thresholds, enter numbers into the text boxes and then click on the “Set Thresholds” button. If you do not
want to use a particular threshold, then make that text box empty, and click on the “Set Thresholds” button.
A humidity threshold may be from 0 to 100. A temperature threshold may be from –40 to 85 if the Celsius radio
button is selected and from –40 to 185 if the Fahrenheit radio button is selected.
