Why should I calibrate?
All instruments lose accuracy over time due to normal usage and the environmental conditions to which they are exposed.
How often should I calibrate?
For most applications, the recommended calibration interval is every twelve months.
What is NIST Calibration
NIST stands for the National Institute for Standards and Technology. This organization is responsible for maintaining the master for different measurements, such as the standard "foot", standard, "second", or standard "pound". NIST also maintains the standard for temperature, humidity and pressure.
NIST Traceable means that the measuring standard can be traced directly back to the master standard maintained by the NIST organization.
NIST-Traceable does not tell you the measurement accuracy of a metrologty service in any detail. Only metrology services that can document their ISO 17025 standard provided data on their best measurement uncertainty.
Frequently Asked Questions
Will I lose any logged data when replacing the battery?
NoCan the High Temp Loggers be used in an autoclave or incubator?
Yes, this logger is perfect for both applications.
Why won't the logger communicate?
- Is the correct version of software being used?
Version 15.5 or higher is required. Please contact customer service if correct version of software is being used and unit still does not communicate. - Make sure the battery is good.
- Make sure the USB cable is not physically defective. Try another cable.
- Make sure that "USB" is selected under File>Preferences>Communications.
- Try another available USB port.
- If this is the first time attempting to communicate on this PC, or if new software or programs have been installed since the data logger was last used, try installing the software on another PC.
- Make sure the logger gets to room temperature if it was just removed from a hot or cold environment.
Why does my downloaded data show a -414 reading?
- You will see a -414 reading if the battery was removed at any time, this marks the point at which logging was resumed once the battery was replaced.
Note: If the logger is dropped on a hard surface, it may temporarily lose the battery connection resulting in a -414 reading. This will not affect other logged data.
