It’s very common for people want to know when their data logger memory is going to be full, and what will happen to their data after the memory is full, and how to deal with it. Actually, your data is specific to your application and not reproducible, so you don’t want your data overwritten before you’ve saved it to your computer and use it. In this article, we will outline what you need to know about how the memory of your data logger works.

What is the memory of your data logger?

It’s important for you to know that your data logger doesn’t become full and then stop storing new data. Rather than that, your data logger’s final-data memory is organized as ring memory. Each data table is its own ring memory. When the table is full, oldest data are overwritten by newest data. So, you should fill the memory of your data logger as determining the point in time when any new data you store will overwrite any old data you have.

What features control how quickly data logger memory will fill?

How much time passes before your data logger memory fills up depends on the following:

The number of records allocated to a table

The number of values being written to the data table each time a record is written

The data types of those values

The amount of memory available in your data logger

The conditions that determine whether new data is added to a data table (such as how often data is written to the table)

How often should you collect data?

Please remember to collect data whenever your new data is about to overwrite your oldest data. Collect your data as often as you can in case to lose it. Instrumentation in the field is subject to conditions outside of your control. It is the best way to collect and review your data to ensure your data logger system is functioning as designed.

Finally

After reading this data logger article, we hope you understand what happens to your data in case of your data logger memory filling up. Your data is invaluable to you, and it’s important to download it from the data logger to your computer before it is overwritten.
