5.2 Setting up Channel Information

In the lower portion of the Levelogger Settings window is the window for setting channel parameters. The software will detect the available channels when the Levelogger settings are read.

For Channel 1, "Level", you can set the following parameters:

Identification describes the measurement parameter of the channel and has already been configured as ‘level’. The level channel monitors water column equivalent pressure. The Identification field will be the data column heading and graph line name when viewing the data. The Identification is limited to 32 characters.

Units refers to the channel’s units of measurement. There are three units of measure available for the user to select: cm, m or ft. When the user changes the unit, the value of the range and altitude will change according to the Unit Conversion formula. Note that when a metric unit is used, the unit of altitude is meters. When feet are the level channel units, feet are the units of altitude.

Offset refers to an offset correction, such as the distance between the tip of the Levelogger and the monitoring well cap or static water level. It is recommended that the value of 0.00 be used for offset as this keeps all subsequent readings relative to the tip of the Levelogger. The offset range for Levelogger Gold or Barologger Gold units is -3280 to 16400 ft or -1000 m to 5000 m. For other Levelogger versions (silver coloured body), the offset field can accept numbers from –327 to +327 when level units are feet and the logger’s level range is either 4.92, 16.40, 32.80, 65.60 or 98.40 ft. For units with range 3280 ft the Offset field boundaries are -3270 to 3270. Similarly, for loggers configured in metric units of level and ranges of 1.500, 5.000, 10.000, 20.000 or 30.000 m, the Offset field boundaries are – 30.30 to +30.30. For units with range 100.00 m the Offset field boundaries are -327 to 327.

Range refers to the full scale water fluctuation range capability of your particular Levelogger model. The full scale reading of any Levelogger unit is based on its metric range. Therefore, the Levelogger, which is available in F15 (M5), F30 (M10), F60 (M20), F100 (M30) and F300 (M100) ranges have actual water level ranges of 16.40 ft (5 meters), 32.80 ft (10 meters), 65.60 ft (20 meters), 98.40 ft (30 meters) and 328.0 ft (100 meters), respectively.

Channel 2: “Temperature”, includes the following parameters: Identification and Units, Reference and Range

The Temperature channel has been pre-configured by Solinst in °C and cannot be changed.

For Channel 3, “Conductivity” or (“Specific Conductance”)

For conductivity, the identification field allows you to choose the actual conductivity at the current temperature or select Specific Conductance measurement in which the conductivity reading is temperature compensated to the standard of 25 deg C.

The range of the second generation (black body) LTC is 80.00mS/cm and provides readings to the second decimal. By scrolling the range field to 30.000mS/cm, the user can obtain readings to the third decimal point. Please keep in mind that the maximum reading is determined by the range chosen, and regardless of range, the accuracy is ± the greater of 1% of reading or 10•S/cm.
