WARNING
Do not subject the
instrument to
extreme temperatures or variations in
temperature.
As an example, do not
leave it in vehicles for long time. In
case of large variations in
temperature, allow the instrument to
adjust to the ambient temperature
before putting it into operation. In
case of extreme temperatures or
variations in temperature, the
accuracy of the instrument can be
impaired.
Avoid heavy impact to or falling
down of the instrument.
After severe
exterior effects to the instrument,
it is recommended to carry out an
accuracy check each time before
continuing to work.
Setting Up the Instrument
Position the instrument on a firm
surface in the horizontal or vertical
(4200HV) position, mount it to a
tripod or to the wall mount with
alignment unit. Due to the high
leveling accuracy, the instrument
reacts sensitively to ground vibrations
and position changes. Therefore,
pay attention that the position of
the instrument is stable in order to
avoid operational interruptions due to
re-leveling.
