If one of the higher-level LK applications (particularly WinCMES) is already installed on your system, a copy of TESTCMM.EXE may be included. LK provides this application, which uses the common driver. You can use it to access the driver setup dialog box and run various CMM operational tests without knowing how to write a program in CMES, DMIS, or any particular language.
TESTCMM can be a useful diagnostic tool. If TESTCMM cannot communicate with the CMM, it indicates a hardware and/or driver configuration problem. A problem prevents higher-level applications (such as the PC-DMIS interface) from being able to use the CMM. Also, if the CMM is mostly operational but a particular type of operation appears to produce an incorrect or unexpected result, you can often try the same operation through TESTCMM. This operation helps to determine if it is an applications-level problem or a lower-level problem in the driver or controller (or both).
