This is what a high temperature alarm looks like on Clever Logger. if this appears on your Locations page, your logger has recorded higher than usual temperatures from the environment it is sitting in.
These include opening the fridge too often or for too long.
You see this as infrequent spikes in temperature, and can usually be tied to busy times of the day or when stock arrives.
This is typically where the fridge has been over stocked and there is not sufficient airflow.
It can also be caused by moving a large amount of warm stock into the fridge.
These include the fridge starting to fail, lack of airflow around the fridge, broken door seals.
You typically see this in the graph as it going over temperature repeatedly throughout the day and night.
When you see a spike every couple of hours (8 to 12), it is probably the defrost cycle.
Contact the fridge technician to fix this.
If you see the temperature going over the threshold every time, the fridge needs to be adjusted down.
Remember that both the fridge and the logger need to be within range. Expect them to disagree on temperature, but both agree they are within range!!!
The most common cause is no power, either from a blackout or from someone pulling out the power chord.
In the event of a blackout, avoid opening the fridge.
It is always recommended to check on your stock when a high alarm is alerting you and rectify the issue immediately.
Ensure the environment is still ventilating correctly. If you suspect the cooling system is not working, contact your refrigeration technician.
It is also important to ask other colleagues if they were doing anything with the logger during the period it was alerting. We get calls and find out a stocktake or re-stocking was in progress hence the fridge door was open.
Check the logger has not be moved or bumped from its original point of placement as it could be reading a hotspot in the environment.

When configuring your logger you would have set a temperature threshold – where a certain range would be considered safe and anything out from those parameters would be cause for concern. We DO NOT recommend increasing it to avoid alarms.
You can also specify the delay before an alarm is generated. This feature is specifically for giving the fridge a chance to cool down again quickly without notifying everyone of a problem. This is our recommended method
Moving the logger to a different location may change the temperature. Note that this is possibly just hiding the fact that you have parts of your fridge that are too warm.
Changing the layout of stock within your fridge (or getting a larger one!) will also change the results.
Another useful trick is to slow the response of the logger down a bit by placing it in box. The logger will typically respond to temperature changes faster than your stock (vaccines, food etc). By placing it inside a box, it will heat up and cool down slower. This removes the extreme highs and lows from the graph. Use a product box or small cardboard box. Do NOT use an enclosed plastic box because this will slow it down too much.
