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 Pen Arm screw secure?

Is the Chart Recorder sitting on or mounted to a surface prone to vibration?

For Temperature units try removing the unit from the application and placing it in an isolated, low air flow environment like a zip lock freezer bag or desk drawer. If the pen traces straighten out, the traces may have actually been caused by the changes in your application.

Please make sure the battery is inserted properly. The battery may be low or the unit may at a temperature below the specified range.

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.

The chart recorder and digital display are actually two independent measuring instruments, with different specifications. There is certain amount of discrepancy allowed between chart and display, the amount of the discrepancy depends on the range of the chart recorder. An SL4120, for example, has a scale of -20 to +120 degrees, that's a range of 140 degrees. That means a 2.8 degree tolerance for the chart. The digital display has tolerance of 3.6 degrees, which means there is a maximum allowed discrepancy of 6.4 degrees between the chart and display. The chart may be adjusted using the pen adjust screw on the face of the unit. If the display is out of specification, the display can be replaced but not calibrated.

Make sure the correct chart is being used.
