  The Nanshan One-meter Wide-field Telescope (NOWT) is a prime focus system
located at Nanshan Station of Xinjiang Astronomical Observatories (XAO). The
field of view(FOV) was designed to 1.5 degree *1.5 degree, and Johnson-Cousins
UBVRI system was chosen as the main Filter set. The telescope has been
providing observation services for astronomers since Sept. 2013. Variable
source searching and time-domain surveys are the main scientific goals. The
system's test results are reported including linearity, dark current, bias,
readout noise and gain of the CCD camera. The accurate instrumental calibration
coefficients in UBVRI bands was driven with Landolt standard stars during
photometric nights. Finally, the limiting magnitudes are given with
signal-to-noise ratios and various exposure times for observers.
