SECTION 1. WEATHER STATION DESCRIPTION The 012 Weather Station is designed to reduce the cost and logistics of routine climatological monitoring. Installation is simplified through a modular design and prewired sensors. This manual covers installation, sensor options, power supply options, programming, maintenance, and trouble shooting.

The battery should be recharged when the voltage The HMP35C Probe requires minimal is below 11 volts. Incorrect battery voltage maintenance. Monthly, check to make sure the readings occur when the battery is low.
SECTION 5. TROUBLE SHOOTING The weather station is divided into sensors and the CR10 datalogger for trouble shooting purposes. Appendix B contains sensor specifications and schematics. 5.1 SENSOR TROUBLE SHOOTING Solar Radiation The *6 Mode is used to display current sensor The solar radiation sensor should measure readings (Section 2.7).
SECTION 5. TROUBLE SHOOTING The CR10 has a regulated 5 volts which can be measured at the serial I/O connector (Figure 2.6-2) using the VOM. Figure 5.2 represents .G.MRK370.PLT;2.5";1.67";HPGL the connector. The 5 volts, ñ1 millivolt, is measured between sockets 1 (+5V) and 2 (ground).
