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

  • Is the Data Logger functioning otherwise? Make sure battery is good.
  • Is the correct version of software being used?
    Minimum requirement is DicksonWare 6.0.2.11 or higher
  • Make sure the download cable is not physically defective.
  • Is the correct COM port selected?
  • Try another available COM port through the software.
  • Has the communication speed (baud rate) been changed? It should be set on ADAPTIVE.
  • Check Com port allocations in the PC's Device Manager, make sure the COM port you're trying to use is not "reserved" for something else.
  • Try another data logger. (if available)
  • Try another available COM port connection on back of PC.
  • 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.
    (not a laptop)
  • Make sure the serial cable is pressed firmly into the unit, on newer units you will feel multiple clicks as you press it in
  • Is it possible that the logger was programmed to fill up storage space quicker than originally thought? Check the sample interval.
  • Is the logger set up to WRAP as opposed to STOP when full?

Yes, this logger is perfect for both applications.

  • 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.
  • 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.
If the o-ring on the USB/Probe end comes out, simply reinsert the o-ring as far into the case as possible and screw in the probe cap. The cap will push the o-ring back into position.
The logger may not have been cleared prior to use. Please clear the logger before placing the unit in service.
