The improved M02A version of the M0 (mechanical and optical) type of accelerograph, currently in use in the N.Z. strong-motion recorder network is described. The improvements relate mainly to the mechanical drive, including the film rewind, and to the electronics for the timing features. In particular the elapsed time from a previous visit to the instrument is obtained by interrogating a clock during the running of the film. Production of the M02 instrument has been suspended in favour of the M02A and all the instruments in the N.Z. network will be converted to M02As.
