communication peripheral
At the data logger:
1. Make sure the battery has been installed and the power switch set to ON (
(p. 55)).
2. Use a voltmeter to measure the voltage on the 12V and G terminals (
(p. 56));
the voltage must be between 9.6 and 16 VDC.
3. Use a voltmeter to measure the voltage on the 5V and G terminals (
(p. 56));
the voltage must be between 4.9 and 5.1 VDC.
4. Make sure the data logger is connected to the communication peripheral, and the
communication peripheral is properly installed and configured (
(p. 35)).
At the computer:
1. Make sure calling software is properly configured (PC200W, VisualWeather, or LoggerNet).
