Regarding the certificate of calibration that can be requested, how long are the certificates good for? Upon expiration is there a way to get them recalibrated without having to purchase a new unit each time they expire?

Asked by: barr
Thanks for the question? The calibration is good for one year, and recalibration cost would be determined by Customer Service- CSERVICE@OMEGA.COM or 1-800-622-2378.

When the max number of readings is reached (43,000 readings), can you delete the readings and start over, or does the reader quit logging data at that point?

Asked by: Lastreaderquitat32000read
When you program the logger you can slect to either stop on memory full or start over writing the oldest data

Model OM-HL-SP-TH how do you switch from C to F?

Asked by: gsladky
Hello, thank you for your question. When you are setting up your logging session through the software, it will let you assign a name to the logger and change parameters like sampling rate or temperature type for C or F.

If I used 32 of dataloggers can the software that comes with it handle that many. In other words can I look at a graph with all 32 sensors on it at the same time.

Asked by: FFCC
Hello Regarding your request, you can connect as many of the units as you need to at a time, depending on the capability of your computer. Though the loggers will only plot the data on individual graphs, they will not merge together on the same graph. Also they are not meant to record in realtime on the computer, you set up the logger on the software, bring it to its environment, then connect back to the computer to download the data afterwards.

Is there a way to transfer the data into a computer programmatically, for example, using python, c++, or LabVIEW? LogPro is nice but we hope to integrate the software into a proprietary software so that we can stream the log into a computer constantly.

Asked by: Anonymous2021
Thank you for your question. Unfortunately, there is not. Just the available software.
