The brief Antarctic summer gives astronomers little time to maintain the equipment at their telescope test site in the remote Antarctic interior. They demand tools they can rely on: Fluke 189 and 179 digital multimeters (DMMs). Since 1996, astronomers from the University of New South Wales (UNSW) have sought the perfect location for the next generation of deep-space telescopes. They may have found it in perhaps the most difficult environment on earth, 1000 km from the Antarctic coast and 3260 meters above sea level.
