
Temperature Reading. This displays the current temperature (Fahrenheit or Celsius as selected in HOBOware) on the
LCD. Internal sensor has temperature measurement range of ‐ 20°C to +50°C ( ‐ 4°F to +122°F). Notes: There may be slight
variations between the displayed temperature value and the logged value due to limits in display conversions. The
values seen in HOBOware and the U ‐ Shuttle are the actual recorded values and the most accurate. The displayed
temperature on the LCD screen may be ±0.3°C (±0.6°F) different than the logged value. Fahrenheit values of 200° and
higher are displayed as three digits without a decimal (e.g., 205°F); however, the full resolution value will be recorded in
the logger memory (e.g., 205.4).

Relative Humidity (RH) Reading. This displays the current RH on the LCD. The internal sensor has a measurement range
of 0% to 100%.

Alarm Icon. This displays alerts as configured within HOBOware. Specifically, ALERT indicator signals when temperature
or relative humidity limits have been exceeded. ALERT DELAYED if you have delay enabled and an alarm is tripped.
Triangle with exclamation mark immediately after delay (if enabled) indicates that the relay is in an alarm state.

Battery Level. Remaining battery level is indicated by a five ‐ segment bar. The number of segments decreases as battery
level decreases. Batteries should be replaced when the BATT LEVEL bar graph is down to one segment, which indicates
20% battery life or less.

Remaining Memory. Remaining memory is indicated by a five ‐ segment bar. The number of segments decreases as
remaining memory decreases. NOTE : If the memory is full, the logger will no longer log. The logger will continue to
monitor conditions however, and will trigger an alert if the reading falls outside of the configured range. You must
readout the logger and then relaunch it using HOBOware to resume logging.
LCD Indicators
Alarms
If the temperature or RH measured by the logger falls outside the selected high or low
limit, the word ‘Alert,’ an alert symbol, and the temperature or RH measurement that
went out of limits will flash. If you set the number of samples to greater than 1 and the
measured value is outside the limits, ALERT DELAYED will flash until either the number
of samples is reached ( ALERT with a triangle symbol is displayed) or the alert condition
no longer exists.
Battery Level BATT LEVEL bar graph down to one segment indicates 20% battery life or less. Batteries
should be replaced.
Condensation (
100% RH) 100% RH is displayed if a temperature/RH sensor is connected and is covered with
condensation. The sensor will not provide accurate readings until it has dried out.
Unread Data If the logger has been stopped, either manually or because the memory is full, the MEM
LEFT hash marks will blink indicating there is unread data.
Memory Remaining memory is indicated by a five ‐ segment bar. Segments decrease as remaining
memory decreases. The MEM LEFT bar graph will decrease as the memory is filled.
When the memory has been completely filled, the MEM LEFT display will flash and all
segments will be off. The HOBO U14 will continue to monitor conditions however, and
will trigger an alert if the reading falls outside of the configured range. You must
readout the logger and then relaunch it using HOBOware to resume logging.
