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
How do I change the chart rotation between 24 hours and 7 days?
- Open the front door and remove the battery. Remove the four screws in the corners of the face plate. Carefully lift the face plate out of the case. Move the clock motor switch to the left for a 7 day rotation and to the right for a 24 hour rotation.
Why doesn't the chart rotate?
Make sure the chart is not hung up or restricted.
Make sure the pen does not have too much tension, pinching the chart to the dial plate.
Make sure there is a good battery being used and it's in correctly.
Make sure the center strip of the chart is inserted properly into the black center hub of the recorder, making sure the chart is not ripped or torn.
Why won't the pen respond to pressure changes?
If the pen does not respond to pressure changes there may be a clog in the capillary. The unit will need to be serviced by Dickson.
