Should you experience difficulty establishing a reliable connection at 19200, try the slower connection speed. Note that due to the slower baud rates and the additional handshaking performed during modem communication, The Global Logger software will operate significantly slower than during a direct connection.
  • Page 12 All options and features work the same but at a reduced communication speed. When connecting the WL16S Data Logger to an external modem, a special cable is required. Wiring diagrams are provided at the end of this manual and pre-wired cables are available from Global Water.

    Global Water 800-876-1172 • globalw.com Main Screen: The main screen is where the status and option menus are accessed. The WL16 data logger will continue to log at normal intervals while connected to the Global Logger software. While connected, the logger will draw an addition current from the power supply of 5-10mA so it is advised that, if you plan to not access the logger for extended periods of time, you disconnect to increase battery life.

  • Page 24 Global Water 800-876-1172 • globalw.com The calibration of channel one to a water level sensor is discussed in the following example where it is not possible to calibrate the sensor over its full range. The water level sensor shown is designed to measure over the range of 0-15 feet but a water column of 15 feet may not be available.
