User Screens
The three User Screens can be reconfigured to display the most appropriate information for your
application. For example, if you need to monitor the wind speed, humidity and barometric pressure, a
User Screen can display these current measurement values on the same screen for quick reference. Only
current measurements can be selected for the User Screens - Min/Max/Avg and Charts are not available.
Highlight the desired User Screen by pressing the or button. Press the button to select the
highlighted User Screen. Press the or buttons to change lines, and the or button to scroll

The display Contrast and Auto Shutdown can be reconfigured as required. The relative humidity and
pressure sensors can also be recalibrated. Press the or buttons to highlight the appropriate
selection, and the or button to adjust or select.
The Contrast can be adjusted for better visibility depending on the ambient lighting conditions. Press

through the Auto Shutdown options (15 minutes, 60 minutes, Off). Battery life will be shortened if the
Auto Shutdown is turned to Off.
Baro Cal - Recalibration of this sensor is not typically required, and it is not recommended that you recalibrate
without speaking to an NK technician. The pressure sensor can be calibrated if necessary. It is extremely
important to know the precise altitude and mean sea level barometric pressure at the time of calibrating
the sensor. First, set the reference altitude on the BARO measurement screen to the known altitude
(see Pressure Adjustment section for instructions). Then adjust the calibrating setting on the Baro Cal
screen to the known mean sea level barometric pressure. If recalibration is desired, the unit may also be
returned to NK for service.
Humidity Cal - Recalibration of this sensor is not typically required, and it is not recommended that you
recalibrate without speaking to an NK technician. The humidity sensor can be calibrated by “teaching” it
