GlossaryReading: Measurement from a single channel (parameter).Redox potential, see Oxidation-reduction potentialReference (water level measurements), see Level referenceReference electrode: A standard electrode of known potential againstwhich the measurement or sensing electrode is compared.Repeatability: Closeness of the agreement between the results of successivemeasurements carried out under the same conditions.Reproducibility: Closeness of the agreement between the results ofmeasurements of the same measurand carried out under nearlyidentical conditions but after an intermediate change was madeand removed.Resistance thermometer: Temperature sensor that changes electricalresistance with temperature.Resistivity: The reciprocal of conductivity; calculated from conductivity.Resolution: The smallest unit that can be measured by a device overits full range.Response time: Time required for the MP TROLL to power a sensorand the sensor to return an accurate reading.Restrictor: Perforated stainless steel area of the MP TROLL 9500between the nose cone and the body; protects the sensors andallows free circulation of environmental fluid.RDO: Rugged optical dissolved oxygen sensorRS-485: Communications protocol using Recommended Standard485 of the Electronic Industries Association (EIA-485) for theorderly transfer of electrical data signals; a balanced (differential),multipoint Interface Standard that uses two lines to transmit/receivedata and can operate at 100 Kbps with cable lengths up to 4000feet.RTD: Resistance temperature detector, a type of resistance thermometerthat has nominally 100 Ω at 0°C.RuggedCable: Waterproof, submersible, TPU-jacketed ventedor non-vented cable for a Multi-Parameter TROLL 9500; carriespower and communication signals; provides strain relief and ameans to anchor the instrument to a stationary object; Twist-Lockconnectors on both ends, Rugged (titanium) or Standard (carbonfilledABS plastic); halogen-free version available.S, see SiemensSalinity: A measure of the amount of salts dissovled in water, usuallyexpressed in parts per thousand (ppt); calculated from conductivityand temperature.Saturation: The point at which a substance contains a maximumamount of another substance at a given temperature and pressure.SC: Specific Conductance, conductivity corrected to 25°C.SDI-12: A serial-digital interface operating at 1200 baud.Sensor kit: Package containing an In-Situ sensor, along with necessaryinstallation items and instructions for installing in the Multi-ParameterTROLL 9500.SI: International System of Units.Siemens (S): SI unit for conductivity, reciprocal of the ohm; this unitwas formerly known as the “mho” (ohm spelled backwards).Site node: Topmost node in the Win-Situ or Pocket-Situ Navigationtree, representing the host computer.Slope: Sensor response vs. concentration (quantity). Slope and offsetare the coefficients calculated during calibration that convert analogmeasurements to user units.Slug test: Aquifer characterization test that involves “slugging” a wellwith a known volume of fluid or solid and measuring the time ofrecovery to stable conditions.Soak time: Length of time a sensor is immersed in a calibration solutionor sample, ideally at the same temperature at which measurementswill be taken.Sodium nitrate (NaNO 3): A salt used to make nitrate calibration standards.Specific conductance: Conductivity of a solution at 25°C.Standard Methods: Approved methods of analyzing for water-qualityparameters, as specified in the reference work Standard Methodsfor the Examination of Water and Wastewater, published jointly bythe American Public Health Association, American Water WorksAssociation, and Water Environment Federation.Stirrer: Battery-powered motorized low-power stirring mechanism withmagnetic stirring bar for use during calibration and/or in stagnantwaters.Submersible cable: Waterproof, quick-connect cable designed for submersion;Instrument backshell located at downhole end; surfaceconnector at surface end.TROLL 9500 Operator’s Manual151 0095110 rev. 007 01/09
GlossarySurface connector: Multi-function vented nylon connector at the surfaceend of the MP TROLL’s submersible cable; accommodates avariety of top-of-well devices for communications, networking, andpower supply.TDS, see Total Dissolved SolidsTefzel ® : Dupont ® ’s modified ETFE fluoropolymerTemperature, Solution temperature: Amount of heat present in thesolution in which the instrument is submerged.Test: Instructions to the MP TROLL’s internal logger for collectingdata; the logged data from one set of instructions.Test node: Node in the Win-Situ or Pocket-Situ Navigation tree, representinga single test.Tests node: Node in the Win-Situ or Pocket-Situ Navigation tree,providing a view of all tests currently stored in the device memory.TOC (Top of Casing), see Level—Top of CasingTorr: A unit of pressure, equal to 1/760 atmosphere.Total Dissolved Solids (TDS): The amount of dissolved substances,such as salts or minerals, in water remaining after evaporating thewater and weighing the residue. Calculated from conductivity.TROLL Com: Communication cable interface between MP TROLL9500 and a desktop/laptop PC or RuggedReader handheld PDA.Turbidity: A measure of the transparency of water.Twist-Lock Hanger: Back end hanger without venting or communicationcapabilities; allows use of inexpensive hanging cable whiletaking absolute (non-vented) pressure data with a preprogrammedinstrument.Units: Measurement units; user-selectable in software interface.Vented cable: RuggedCable with a vent tube that applies reference atmosphericpressure to the back of the pressure sensor diaphragm.Vented pressure sensor, see Gauged pressure sensorVertical profile: Characterization of a water column from surface tobottom (or vice-versa) through multiple real-time readings of thewater-quality parameters of interest taken at varying depths.Win-Situ 4: Instrument control software for instrument setup, calibration,profiling, data logging, data retrieval and display.ZoBell’s: A redox standard solution with a known state of oxidation-reductionpotential (measured in milliVolts) used to calibrate ORP.TPU: Thermoplastic Polyurethane, a cable jacket option.TROLL 9500 Operator’s Manual152 0095110 rev. 007 01/09
