DMX512 and MIDI are now common place digital protocols and so specific test equipment is no longer a luxury. Micro-Scope 3a provides all the features regularly needed by both theatre and touring staff. Micro-Scope 3a is a small hand-held DMX512 receiver and transmitter. It can operate as a Moving Lamp tester, a Flicker Finder or as a Rigger's Remote. It is powered by an internal rechargeable battery, with a normal life of 25 hours and uses a high brightness backlit LCD screen. Micro-Scope 3a is very simple to operate. Switch on and you are immediately displaying received DMX512. Two key presses are all that is required to start flashing through the rig.
