9 Care & Maintenance
Operating Considerations
The Aqua TROLL Instrument 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 Aqua TROLL temperature sensor operates within a
temperature range of -5° to 50° C (23° to 122° F) in non-freezing
fluid.
Pressure Range
The Aqua TROLL 200 Instrument 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 pressure sensor will be
destroyed.
Factory Calibration
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 such
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. Any
damage associated with ice
formation is not covered by the
warranty.
