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.

How do I know if an alarm condition has been detected?

If an alarm condition has been detected, the LED will blink green, then red while sampling. An alarm will persist until cleared using the Dicksonware Alarm Level Update or the memory CLEAR button.

Why is the LED flashing red?

Untitled Document
  • The LED will flash red if the logger is set for a delayed start.

Why is the unit flashing green or not at all?

There is an LED indicator located on the front lower right corner of the unit. This indicator will flash green every 10 seconds ONLY when the unit is sampling and operating properly. If the indicator is not flashing, please verify the following:

The logger memory may be full; download the data and clear the memory.

Sampling may not be activated. To start sampling clear the memory.

The battery may need replacing (Battery Level may be checked via Dicksonware using USB power), or is installed upside down. See battery Replacement.

Condensation may have formed on the unit. Place unit in a warm dry environment for 24 hrs.

Clear memory and try again. These loggers are designed for use in a non-condensing environment.
If the environment creates condensation, try placing the unit (temperature only models) in a small sealed plastic bag to protect it from condensation.
