Cleaning and Maintenance
Overview
It is important for users to perform scheduled maintenance on their instruments to
sustain the accuracy and longevity of the probes and cables. The frequency of this
maintenance depends on the characteristics of the deployment site, including humidity
levels and the degree of fouling.
Users should be aware of the conditions at their deployment sites and develop
appropriate maintenance schedules to replace desiccant, clean the instruments, and
send in the instruments for factory calibration. Users should check instruments often
during the first portion of the deployment to determine the frequency of maintenance.
General maintenance should be performed as often as possible. In-Situ Inc.
recommends that you send your instrument in for factory service at least every 12
months.
Operating Considerations
The 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
Review the instrument specifications to determine the operating range. Do not deploy
instruments in such a way that ice may form on or near the sensors or cable
connections. Ice formation is a powerful expansive force that can over-pressurize the
sensor or otherwise cause damage that is not covered by the warranty.
Pressure Range
The 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 sensor will be destroyed.
Batteries
Internal batteries in the instrument are not user-replaceable. The approximate
percentage remaining is displayed on the Win-Situ 5 Dashboard when the instrument is
connected in software.
If batteries are completely exhausted, external power and battery pack options are
available. See page 23.
