Enter the temperature offset using the TCAL command. Please refer to
Section 4: Operation for more information.
Record the temperature offset on a label attached to the sensor.
Repeat the process for any other temperature sensor.
Calibrating the Humidity Sensor
The humidity sensor is calibrated at the factory. No field calibration is
required.
The humidity sensor has a ±2% stability over 2 years. Therefore we
recommend replacing the sensing element every 2 to 4 years.
Calibrating the Rain Gauge Sensor
The rain gauge is calibrated at the factory and does not require any initial
field calibration.
The tipping bucket mechanism is a simple and highly reliable device. The
transmitter must be located in a clear area, away from trees, buildings,
etc. It must also be mounted level. Accurate readings will not be obtained
unless the transmitter is mounted in a level position. The mechanism
must be clean. Any accumulation of foreign material, dust, etc. will alter
the calibration of this unit.
Absolutely accurate calibration can be obtained only with laboratory
equipment, but an approximate field check can be easily made.
For field calibration, a calibration kit is available from the factory.
Calibrating the Leaf Wetness Sensor
The leaf wetness sensor is calibrated at the factory. No field calibration is
required.
Calibrating the Solar Radiation Sensor
The solar radiation sensor is calibrated at the factory. No field calibration
is required.
