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
If the alarm condition clears before the alarm delay period has passed, the display will automatically clear the ALRN notification.
If the alarm delay period has passed and the alarm sounds before the alarm condition clears, the alarm will continue to sound and the display will flash ALRN until the ALARM button is held down till CLR is displayed. This will clear both the audio and visual alarm notification. NOTE: Once the alarm sounds, it will continue to sound regardless of whether the alarm condition still exist.
Verify that you have the correct version of DicksonWare software installed on your PC. Version 10.0 or higher is required.
Verify that the correct COM port is selected: From the main Dicksonware screen, click on Logger then Communication, a black dot will appear next to the selected COM port. You may need to select a different COM port. Should you get an error message stating that Device Is Already Open, this could mean that you have the proper COM port selected, but another device, or its software, has it allocated. Palm pilots, for example, will cause this problem, in which case the port is not actually available and you may haveto disable that device.
You may need to relocate the download cable to another serial port on the back of the PC and possibly try changing the COM port again in DicksonWare.
If communication has not been established with the previous steps, you may need to open the logger and press the reset button and then try all COM port and cable combinations again.
If possible, try another PC
Make sure that either Serial or USB is unplugged, and that either Serial / USB is NOT checked in File > Preferences > Serial / USB.
Unit may be locked up, try removing the battery and then replacing after a few moments.
Battery may be to low or dead, replace batteries
- This means that the unit does not recognize the external probe, check to see that it is connected properly. If it is connected properly, there may be a weak internal connection and should be returned.
- Is there an extension cable being used? It could be defective. Omit the extension cable and try another K-type probe.
- This is normal when an activated channel has no probe connected at the time a sample is taken.
- Yes, they can be changed using Dickson software.
Channel 2 can be disabled by doing the following: Open DicksonWare software. Choose "Setup". Choose "Channels" tab. Choose "Adjust" for channel 2. Under the "Enable" tab, uncheck the check mark. Choose "Adjust" to accept the change. Choose "OK" in the dialogue box to clear and restart logger. Channel 2 will be grayed out under "Channels" tab. Disabling this channel will not make the alarm inactive. Be sure to disable the alarm or set it to an unobtainable min/max.
The Flash Memory Download Feature was designed to work with standard MMC cards. MMC Plus cards can cause the unit to stop logging when used to download data. If you think the unit stops logging when the Flash Memory Download Feature is used, you might be using a MMC Plus card. We recommend using Dickson Flash Memory Cards.
Replace the batteries, they may be low.
