General Safety
HVR systems are designed for safety and proper ergonomics during normal use. Exercise caution when lifting, handling or moving the system to avoid personal injury and to maintain equipment calibration and measurement performance. Disconnect all power sources prior to moving or working on the equipment. Consult Starrett if you have any questions regarding transporting, using or maintaining this system. HVR systems do not contain hazardous AC line voltages, as these are contained on the input side of the system AC adapters, which are UL listed. The supplied voltages are 24 VDC to the metrology unit and 19.5 VDC to the PC. Even at these low voltages, there is the potential of electrical component damage caused by accidental short circuits. For maximum electrical safety and minimal risk to the equipment, follow the guidelines below: • Ensure that the power receptacles for the AC adapters are properly grounded. 3-prong polarized 120V AC types for

use in North America or appropriate safety-rated receptacles for use outside of North America.
• Do not operate the system with the housing open except for service by a factory trained technician. • Keep liquids away from the system and do not operate the equipment in excessively humid conditions, as water can cause short circuits. • Keep metal filings away from the system, as such debris can cause short circuits. • Do not operate the equipment around volatile or flammable solvents, as local electrical heating could cause ignition. • Disconnect power, or do not plug in the power cord, if hazardous conditions exist such as a damaged or frayed power cord, a damaged or improperly grounded power receptacle, equipment exposure to liquid spills or excessive moisture, or impact damage. Have the system inspected by authorized personnel before operating. • There are no fuses or user-serviceable items in the system. The system should only be opened by a factory-trained service technician. The HVR100 system weighs 106 pounds. Switching the system from the vertical to horizontal position requires two people. Do not attempt to move the system without proper assistance.
