We describe system verification tests and early science results from thepulsar processor (PTUSE) developed for the newly-commissioned 64-dish SARAOMeerKAT radio telescope in South Africa. MeerKAT is a high-gain (~2.8 K/Jy)low-system temperature (~18 K at 20cm) radio array that currently operates from580-1670 MHz and can produce tied-array beams suitable for pulsar observations.This paper presents results from the MeerTime Large Survey Project andcommissioning tests with PTUSE. Highlights include observations of the doublepulsar J0737-3039A, pulse profiles from 34 millisecond pulsars from a single2.5h observation of the Globular cluster Terzan 5, the rotation measure ofTer5O, a 420-sigma giant pulse from the Large Magellanic Cloud pulsar PSRJ0540-6919, and nulling identified in the slow pulsar PSR J0633-2015. One ofthe key design specifications for MeerKAT was absolute timing errors of lessthan 5 ns using their novel precise time system. Our timing of two brightmillisecond pulsars confirm that MeerKAT delivers exceptional timing. PSRJ2241-5236 exhibits a jitter limit of <4 ns per hour whilst timing of PSRJ1909-3744 over almost 11 months yields an rms residual of 66 ns with only 4min integrations. Our results confirm that the MeerKAT is an exceptional pulsartelescope. The array can be split into four separate sub-arrays to time over1000 pulsars per day and the future deployment of S-band (1750-3500 MHz)receivers will further enhance its capabilities.
