Introduction Controls and Indicators Use the UEi THL1 to log temperature and humidity values for later analysis. Verify cold storage requirements are being met, or test temperatures and humidity for comfort analysis.
* To save power, the logger’s LED flashing-cycle can be changed to 20 or 30 seconds via the supplied software. ** To save power alarm LED’s for temperature and humidity can be disabled via the supplied software. *** When both temperature and relative humidity readings exceed the alarm levels the LED status indication alternate every cycle. For example if there is only one alarm cycle the “REC” LED will blink for one cycle, and the Alarm LED status will blink on the next cycle.
