	A dedicated 68 MeV, 70 mA proton injector is required for the research program at FAIR (Facility for Antiproton and Ion Research). This 325 MHz linear injector contains a RFQ and six CH structures. The CH (Crossbar H-mode) structures are working in the H₂10 mode. The main acceleration of this room temperature linac will be provided by the CH structures. For the second acceleration from 11.5 MeV to 24.2 MeV a full scale prototype has been built. This structure consists of two individual CH resonators and a coupling cell. Inside the structure there are 17 tuners, they have an impact on the electric field and the frequency. For operation a flat field is required, therefore this tuners must be correctly positioned. Some series of low level tuning and frequency measurements were done to determine the size of the tuners. Low level measurements and simulations will be compared and presented.
