A new hand-held multiscope is offered by extech instruments corpn, u.S.A. . This combines a 100 khz graphical storage oscilloscope with a true rms multimeter. Test technicians will appreciate the square wave [ttl level] generator for general trouble shooting and testing. Some special features of this multimeter include: built-in rs-232 interface with optional software; help screens include connection diagrams and safety precautions; trigger level adjustment captures a waveform the technician wishes to see; temperature measurement [with optional adaptor]; and, up to 15 waveforms can be stored for later analysis. Test technicians will appreciate the square wave [ttl level] generator for general trouble shooting and testing. Maintenance personnel will value this multiscope as a visual dmm. They will find it easier to observe noise and distortion by looking at the waveform rather than numbers when measuring voltage or current. X
