This document is the user manual for the Digi-Sense 20250-23 Compact Vane Anemometer. The instrument measures air velocity in units of m/s, MPH, FPM, KNT, and KPH. Advanced features include an automatic backlight, MAX/AVG readings, and automatic power-off. The instrument is fully tested and calibrated to NIST-traceable standards. Careful use of this meter will provide years of reliable service.
This user manual provides instructions for operating the Digi-Sense 20250-23 compact vane anemometer, including how to take measurements, use the backlight, and manage battery life. It also details technical specifications such as measurement range, accuracy, and environmental operating conditions.
The device features automatic backlight, MAX/AVG readings, and automatic power-off after 15 minutes. Calibration is NIST-traceable, and annual recalibration is recommended for accuracy.

It measures air velocity in m/s, MPH, FPM, KNT, and KPH.
Typically 100 hours, but reduced if the backlight is used continuously.
32 to 122°F (0 to 50°C).
Annually, though regulatory bodies may require more frequent calibrations.
