At Institute of High Energy Physics (IHEP) in Beijing the C-ADS project has started beam commissioning. A newly developed double-slit emittance meter (DEM) for pulsed proton beam from the (RFQ) has been installed in the beam line. In this paper principal of operation, instrumentation and programming of emittance meter are discussed. The emittance measurement has been carried out with the newly developed DEM at a beam energy of 3.2 MeV and a beam current of 10 mA. Typical rms emittance for x and y direction are measured to be 0.1303 and 0.1347 π mm mrad，which are well below the design standard of the RFQ.
