9 Care & maIntenanCe
operatInG ConSIderatIonS
The Level TROLL has been designed to withstand harsh field conditions.
However, as with any electronic instrument, it can be permanently
damaged if used outside its operating specifications.
temPerature
The Level TROLL and BaroTROLL instruments operate within a
temperature range of -20°C to +80°C (-4°F to 176°F).
Pressure range
The Level TROLL can withstand pressures of up to two times (2X) the
rated range of the pressure sensor without damage, although it may not
read correctly at such pressure. If the pressure range is exceeded by 3X,
the sensor will be destroyed.
FaCtory reCaLIbratIon
Accuracy can be adversely affected by improper care and handling,
lightning strikes and similar surges, exceeding operating temperature
and pressure limits, physical damage or abuse. Factory calibration every
12-18 months is recommended. Contact In-Situ Customer Service for
information on the factory maintenance and calibration plan.
Do not deploy
pressure
transducers in
such a way that ice may
form on or near the sensor
or cable connections. Ice
formation is a powerful
expansive force and may
over-pressurize the sensor
or otherwise cause damage
that is not covered by the
warranty.
