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 adjust the pens?
Pen adjust may be needed if the pen(s) and display do not match. Before proceeding check your calibration date, the unit may be due for a recalibration, if so contact Dickson.
While the unit is on, press and hold both the Pen Home button and the On/Off button (making sure to press the Pen Home button first so the unit will not turn off). The led will blink rapidly between amber and green for about five seconds, the LED will then turn green, release the Pen Home and On/Off buttons. The led will flash amber and green for one second and the led will turn off.
One pen model: The red pen will move to the outer edge of the chart and is ready to be adjusted. Use the Adjust-Up and Adjust-Down buttons to move the pen to the maximum temperature line on the chart. Once the pen is set, the Pen Home button will move the pen to reaffirm the new pen position. Press the On/Off button to exit pen home adjust.
Two pen models: Both pens will move to the outer edge of the chart, and then the shorter red pen will move to the current position. Use the Adjust-Up and Adjust-Down buttons to move the pen to the maximum temperature line on the chart. Once the shorter red pen is set, the Pen Home button will move the shorter red pen to the outer edge of the chart and the longer blue pen will move to its current position. The Adjust-Up and Adjust-Down buttons will adjust the longer blue pen position. Once the pen is set, the Pen Home button will move the longer blue pen to the outer edge of the chart and the shorter red pen will move to its new position. Each time pen home is pressed the two pens will switch positions (moving the most recently adjusted position) until the On/Off button is pressed to exit pen adjust mode.
Note: Pressing the On/Off button will exit the adjustment and return the unit to normal operation. Each time the pen home or On/Off button is pressed, the adjustment currently in progress will be stored. The unit will take one minute to exit Pen Adjust Mode once the On/Off button is pressed.
What do the different colors on the LED Light mean?
Solid Green - AC Power with Battery Backup
Blinks Red - AC Power with Low Battery or No Battery
Blinks Green - Battery Only
Solid Red - Battery Only (Low Battery)
What if my chart does not have an Rh line?
- If your chart does not have an Rh line it uses the same scale as the temperature.
What if my instrument is not responding to a key press?
- Try slower, firmer key presses.
- Maybe the unit is locked up. If the chart recorder is locked up there will be no response to button presses, however, the unit may appear to be working, but the readings won't change and the chart will not rotate. To correct this, remove ac and battery power then re-power.
What if my instrument turns off?
- Check AC adapter connection
