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
Where is the Time Indicator located on the dial?
Time Indicator is the raised part directly to the right and slightly above the pen tip.Why isn't the chart keeping time or running slow?
The chart may be hung up or restricted, possibly caused by a rip on the outer edge of the chart or the chart may be caught between the arm and pen arm platform.
Incorrect chart installed for the selected chart speed.
Manually advance the chart one full rotation with the chart rotation button to ensure that the gears are not binding or slipping.
Why does calibration seem to be off?
What is the tolerance of the unit it is being compared to?
It's ok if the unit is within the sum of the two tolerances
Remember that the unit's tolerance speaks to the Chart Recorder only, there is any additional that applies to the probe
Has an outside calibration house attempted calibration? It may not have been adjusted properly
When was the last time the unit was sent to the Dickson Calibration Lab for a recalibration?
Walk through zero adjustment, found in the manual
For units with Pen Adjustment - rotate screw to adjust the unit to match another unit of greater accuracy after both units have stablized in the same environment.
Chart Recorders - make sure the correct chart is being used.
K-Thermocouple Units
K-Thermocouple capable units are capable of using any K-type thermocouple probe or extension but keep in mind that long extensions to extend the distance may require a Zero adjustment. (Refer to manual)
As a general rule: If the unit is not responding properly, and you have more than one thermocouple, swap probes to see if it is the probe or the unit that is defective.
Voltage Recorders
Make sure the output signal of the transmitter is calibrated to its full measuring range.
Make sure the range selected on the recorder matches the transmitter exactly and that the proper chart is being used.
