Are all accessories compatible with all tester models?
Most accessories are compatible with all models. You can use older accessories with new tester models.
If you own 20-25 years old accessories, some might not be compatible with the new generation models (i.e. Optical Pickup), but all new accessories can be used with old generation testers.
If you have a Metercam with a MT-1/NT unit and you would like to use it with a MT-1/WT model, you will require a different Coiled Cables.
