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

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.

1. Alarm on or off
2. Pen 1 alarm min
3. Pen 1 alarm max
(if it is a two pen unit the following states also exist)
4. Pen 2 alarm min
5. Pen 2 alarm max

To set the alarm, make sure unit is on and press and hold the Alarm button. The LED will blink red rapidly for about five seconds, and then the led will go solid green. Release the Alarm button and the led will turn red. At this point the display will show the following: ON with a delta symbol, or OFF without a delta
symbol.

Pressing either the Adjust-Up or Adjust-Down buttons, located on the back of the unit next to the dip switch, will toggle the alarm on/off.

Pressing Pen Home will scroll to the next alarm option. The options are as follows:

In order to set pen alarm minimums and maximums, pressing the Adjust-Up will increase the alarm value, and pressing the Adjust-Down will decrease the alarm value. There is acceleration if the Adjust-Up button is held down. Repetitively pressing the pen home button will scroll through the five options until the alarm button is pressed to exit from alarm adjust. Each press of the Pen Home or Alarm button will store the new settings. The unit will take one minute to exit Alarm Set Mode once the Alarm button is pressed.

If the alarm is triggered, ALRN will show on the display, the led will show as solid red and the alarm will sound. Press the Alarm button to silence Audible Alarm.
