2t is push and hold 4t is push to start and push to stop. As for the pulse, you have pulse frequency which is pretty self explanatory but you have to set the base amperage and max amperage as well. Make sure all current knobs are at zero before beginning. Then turn up the base current to the MINIMUM current of the pulse. Once that's done you can set the peak amperage for the maximum current. If you do it backwards you won't be able to see the base current settings
