Note: UT is the AC mains voltage prior to application of the test level.
Floors should be of wood, concrete or
ceramic tile. If the floor is of synthetic
material, the relative humidity must be at
least 30 %.
Mains power quality should be that of a typi-
cal commercial or hospital environment.
Mains power quality should be that of a
typical commercial or hospital environment.
Mains power quality should be that of a
typical commercial or hospital environment.
If the user of the Leica HM500 headmounted
microscope requires that the instrument
remain functional even after mains power
interruptions, it is recommended that the
Leica HM500 headmounted microscope be
provided with an auxiliary power source such
as an uninterruptible power supply (UPS) or
battery back-up.
