1 Well Dock Installation Ring 2 Kellems Grip 3 Instrument Installed in Well Install the Desiccant Vented cable must be protected with a desiccant pack that is properly sized for site conditions. Desiccant Desiccant protects electronics from condensation, which can cause irreparable damage and loss of data. Indicating desiccant changes from blue to pink as it becomes saturated with moisture. Desiccant stages (from left) New, nearly expired (replace now), expired 1-800-446-7488 36 www.in-situ.
It is extremely important to use a properly-sized desiccant for your deployment and to change desiccant often. Desiccant should be changed before the entire volume has turned pink, and you should use enough desiccant to effectively keep cables, instruments, and electrical boards dry until your next scheduled maintenance. Desiccant life span is dependent on site conditions. Installation Guidelines l l l l l l Never let the instrument fall freely down a well. Doing so will damage the sensor.
Stabilization Time After you have installed the instrument, allow it to stabilize to the environment for about 10 minutes before logging data. The T95 response time for temperature is less than 9 minutes. A generous stabilization time is always desirable, especially in long-term deployments. Even though the cable is shielded, temperature stabilization, stretching, and relaxing can cause changes to readings.
BaroTROLL Instrument Installation The BaroTROLL Instrument is designed to log barometric pressure from 0 to 16.5 PSIA (1.14 bar, 33.59 inHg) at the surface near a submerged non-vented Level TROLL Instrument or Aqua TROLL 200 Instrument. BaroTROLL data may then be used to correct the water level data for barometric pressure fluctuations. See page 14. Programming the Baro TROLL Instrument Connect the BaroTROLL to Win-Situ 5 Software and sync the clock.See page 51.

Logging Methods for Aquifer Testing True Logarithmic True Logarithmic log type captures early-time water-level data during aquifer testing. Measurements are very closely spaced at the start of the test (4 measurements per second) and move further apart on a logarithmically decaying schedule as the test progresses. There are 40 measurements per log decade. This log type is commonly used for rapid step-drawdown pump tests, constant-rate pump tests, and slug tests.
l New Reference—This option is designed to be used with an active software connection when the device is installed in the water. A new level reference must be entered while the device's pressure sensor is submerged in its final position in the water. This is because the current probe reading is set equal to the Level Reference to create the offset that takes effect at the start of the data log. The log header will show the probe reading at the time you entered the Level Reference.
1. With the instrument connected to the software, select the Logging tab . 2. Select the log you intend to suspend. 3. Click the Suspend button . Suspended appears in the Status column.

Power Connections The Red wire provides power for Modbus and SDI-12 modes. The Brown wire provides power for the 4-20 mA mode. If power is present on the Brown wire and not on the Red wire, the device enters the 4-20 mA mode automatically and stays in the 4-20 mode until power is removed from the Brown wire or is applied to the Red wire. The Red wire has priority. If power is applied to the Red and Brown wires at the same time, the device will operate in Modbus or SDI-12 modes but not in 4-20.
Redundant Logging The instrument is capable of internal logging while participating in a Modbus, SDI-12 or analog network. However, Win-Situ 5 Software cannot communicate with the instrument while it is transmitting Modbus, SDI-12, or 4-20 mA analog data, and the instrument cannot receive or respond to Modbus, SDI-12, or 4-20 mA analog commands while connected to a PC serial port.
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.
Desiccant Pack Options Small Desiccant The Small Desiccant is a disposable cap that ships with In-Situ Inc. products. The small desiccant is meant to protect the instrument and cable only during shipping and should not be used for deployments. Large Desiccant The Large Desiccant is a replaceable desiccant pack designed for low-humidity environments or deployments where maintenance occurs frequently. The large desiccant is available with a plastic or a titanium twist-lock connector.
Extra Large Desiccant The Extra Large Desiccant is a replaceable desiccant pack designed for high-humidity environments or deployments where maintenance occurs infrequently. The extra large desiccant provides six times the drying capability of the Large Desiccant. Description Extra Large Desiccant Part Number 0090420 Desiccant Refill Kit The Desiccant Refill Kit supplies desiccant for the Large Desiccant, Extra Large Desiccant, and the Outboard Desiccant. It also contains replacement glass wool.
Installing Outboard Desiccant Vented cable must be installed with outboard desiccant to protect the cable and instrument electronics from condensation in high-humidity environments. The desiccant can be removed from the vent tube, if necessary, to trim the conductor wires. However, you must reinstall the desiccant after trimming and connecting the wires. 1. Cut off the knot at the bottom of the vent tube extension. 2. Firmly attach the vent tube extension to the cable vent tube. Cover at least 6.4 mm (0.
3. Fill the container with fresh desiccant. Replace the vent cap. Reattach to cable if removed. Antifouling TROLL Shield Nose Cone The copper TROLL Shield Nose Cone is designed to reduce macro- and micro-fouling of the pressure sensor on Level TROLL and Aqua TROLL Instruments. Reduced fouling on the sensor improves measurement accuracy and extends the length of deployments.
Cleaning and Storage Cleaning the Instrument Clean the instrument body with water and a soft brush or plastic scouring pad, or soak overnight in a mild acidic solution, such as household vinegar. NEVER submerge the connector portion of the instrument when it is not connected to a cable. If the ports near the pressure sensor are clogged with silt or mud, try the following procedures. l Agitate the instrument vigorously in a bucket of clean water. l Apply a gentle rinse of water from a wash bottle.
Factory Calibration and Service In-House Factory Calibration Factory calibration of In-Situ Inc. instruments should be performed every 12 to 18 months, or when the unit data appears to drift significantly. Factory calibration includes a thorough cleaning, full functionality check, and adjustments of the pressure sensor, temperature sensor, and conductivity sensor (when applicable) over the entire calibrated temperature range.
