Rain Gauge (Texas Electronics TR-525M)

Table 5‑7. Configuration for Texas Electronics TR-525M or TR-525USW rain gauge.
  • Digital Mod: The Digital In/Out Module to which the sensor is connected. Typically this is 1 unless additional modules are used.
  • Digital Chan: The channel on the module to which the signal is connected.
  • Filter: This can be set to reduce errant bounces of the switch, or to debounce noisy inputs. A value between 1 and 255 requires the input to last a duration of (value*0.2 ms) before the logger will register the count.
  • Slope: m of y=mx+b. 0.254 for the 525USW or 0.1 for the TR‑525M.
  • Offset: b of y=mx+b.
  • Units: Units of the measurement.
  • Reset Count: If this is checked, the count resets every time recording is started.
  • Time: Controls when the software initializes the computation.
  • Interval: Resolution of the output. 00:01:00 instructs the datalogger to output 1 minute totals.
  • Name: Used by the gas analyzer software to identify the variable type and units. See Table 4‑1 to interpret the first number and Table 4‑2 to interpret the second.
  • Prefix: Ignore this field.
  • Suffix: Ignore this field.
  • Right Digits: The number of digits to the right of the decimal (hard stop) for this variable.
  • Name: Recorded in the header of the data file. Default variable names are similar to GHG-Europe standards (see VariableID).
  • Record ID: Tells the datalogger to associate this variable with the Record ID in the LogRec block (see Custom Configurations). It should be the same in both places.
  • Sequence #: The column number in the sequence of variables.
  • Right Digits: Number of digits right of the decimal.
  • Format: The data that is output when logged data is viewed. Typically <val>.
  • Units: The units entered will override previous entries.
The Display block is used select data that gets displayed on the I2C Display. The data displayed is the last measured value for the block connected to the display block. The data is displayed at the requested precision (right digits) with the selected Label.
Units for the TR-525M are mm.
