Parameter Instruction
Users can reconfigure the parameters by data management software per actual needs. The the original parameters and ata will be cleared.
| Alarm threshold | This data logger supports 3 upper temperature limits, 2 lower temperature limits, 1 upper humidity limit and 1 lower humidity limit. | |
| Alarm zone | The zone which beyond the alarm threshold | |
| Alarm type | Single | The data logger records the single time for continuous over-temperature events. |
| Cumulative | The data logger records the cumulative time of all the over-temperature events. | |
| Alarm delay | The data logger does not alarm immediately when the temperature is within the alarm zone. It begins to alarm only when the over-temperature time elapses the alarm delay time. | |
| MKT | Mean kinetic temperature, which is an evaluation method of the temperature fluctuation effect on the goods in storage. | |
Operating Instructions
This data logger can be stopped by software. Users can stop the logger by clicking the stop button in the data management software.

View data When the data logger is inserted into the USB port of the computer, the data report will be created automatically. The red and green indicators flash in turn when the document is being created, and the LCD screen shows the progress of PDF Report creation. The red and green indicators light at the same time immediately after the document is created, then users can view the data report. The document creation will last for no more than 4 minutes.
(1) Rotate the transparent cap in the direction of the arrow and remove it.
(2) Insert the data logger into the computer and view the data report.
