2.2 Environmental Conditions
Operating Conditions
AVR systems can be safely operated under the following environmental conditions:
If the system is to be operated under environmental conditions that are substantially different
from those in the previous table, the system should be recalibrated under the expected
conditions. Users should also consider the material characteristics of the parts under
inspection, in particular coefficients of thermal expansion. Numerical compensation might be
required when measuring parts under conditions different from those controlling the stated
dimensional specifications for these parts.
Before performing critical parts measurements, allow the system to warm up for 30 minutes
and use the system’s joystick to cycle the X, Y and Z axes ten times.
Factory Calibration Conditions
AVR systems are factory calibrated under the standard laboratory environmental conditions
shown below:
20°C ± 0.5°C (68°F ± 5°F)

2.3 Safety Considerations
General Safety
AVR systems are designed for safety and proper ergonomics during normal use. Exercise
caution when handling or moving the systems to maintain calibration and measurement
performance. Disconnect all power sources prior to moving or working on the equipment.
Consult SKE if you have any question regarding transporting, using, or maintaining the
systems.
Electrical Safety
AVR systems do not contain hazardous AC line voltages, as these are contained on the input
side of the system’s AC adapters, which are UL listed. 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, adhere to the following
guidelines:
