Didn't the unit come with instructions ?
Most logic probes indicate whether the signal being probed is high ( logic 1 ) or low ( logic 0 ). Some will detect a short pulse that is too short to be seen by the eye and display it long enough to be seen. These can misslead you as two or more short pulses may appear as just one long pulse.
Logic pulsers must be used with care...
They force a signal line to the opposite state to which it is. Forcing the signal this way can damage the device that is producing the signal. The device and the pulser are fighting each other and high currents can flow and overload the device on the PCB. Very seldom does the pulser suffer damage.
The damage may not appear for some time ( days ) after the pulser has been used or it may be immediate.
Using a pulser on the ouputs of any modern micro-processor is to be avoided.

Then wots the point of me buying the probe if its NOT 2 BE USED???????

The probe can be used to see what is happening on a signal line.
The pulser can be used but with care to avoid causing damage to the more fragile components used in electronics.
