What is a limit violation event?

A consecutive series of data points over a high limit (or under a low limit) is deemed as an alarm event.

For example, in image below, there are 3 temperature high limit violation events for high alarm zone.

Error codes

Error codes usually could be found on the upper left corner of a PDF report created by data logger, if you find an error code in a data report, it means data logger detected an exception during recording.


Code 0004 (*0004), logger used to be reset during recording, which may cause missing of data point.

Code 0005 (*0005), an internal time error is detected when activating a logger, to avoid creating incorrect data record, logger would not be activated in this case until new configuration is effective.

What is Alarm Type?

Alarm type defines different types of calculation method for determining an alarm. So far data loggers made by TempSen support two alarm types, see below. 1. Single alarm 2. Cumulative alarm Single alarm means an alarm only could be triggered when measurement values over high limit (or below low limit) for a continuous period of time which is not less than a set alarm delay, cumulative alarm means alarm could be triggered once the cumulative total time measurement values over high limit (or below low limit) not less than a set alarm delay.

What is Alarm Delay?

Alarm delay is a time threshold to determine when alarm should triggered after alarm limit has been keeping violated, only limit has been violated for this set period would trigger an alarm.
