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

Make sure that USB is selected under File > Preferences > Communications.

Unplug USB cable and plug back in or try another USB cable.

Install a new battery (this will not cause the unit to lose any logged data, but the unit will stop logging and will need to be restarted using DicksonWare).

If possible, try another PC, and/or another USB port.
