CALIBRATION

KT8P0/2/3:

The R400 Replaceable Sensor was carefully tested and calibrated before being shipped

from the factory. For greatest accuracy, we recommend replacing the sensor every 6-12

months (does not include N400 and N450).

To order a Calibrated Replacement Sensor Call customer service at (630) 543-3747 or go

to www.dicksondata.com.

When your new Replaceable Sensor arrives, simply turn off the recorder, remove and

discard the old sensor, plug in the new one and power the recorder back on. Your

recorder will continue to record temperature and humidity without interruption.

KT856:

The KT856 was carefully tested and calibrated before being shipped from the factory. For

greatest accuracy, we recommend factory re-calibration every 6-12 months. Call

customer service at (630) 543.3747.

USER CALIBRATION

If you have an accurate standard to compare against, the Replaceable Sensor or unit (KT856)

recalibration.
