ESD Protection
Electrostatic Discharge (ESD) can cause immediate or latent damage to
electronic circuits. The Pulsar is adequately protected against ESD for its
intended use. However, it is possible to damage the product by
delivering electrostatic discharges when touching, removing, or inserting
any objects inside the equipment housing.
To avoid delivering high static voltages yourself:
1. Handle ESD sensitive components on a properly grounded and
protected ESD workbench. When this is not possible, ground
yourself with a wrist strap and a resistive connection cord to the
equipment chassis before touching the boards. When neither of
the above is possible, at least touch a conductive part of the
equipment chassis with your other hand before touching the
boards.
2. Always hold the boards by the edges and avoid touching the
component contacts.

Principles of Measurements
Temperature & Relative Humidity
Temperature is measured by way of a highly accurate NTC-resistor while
humidity is measured using a capacitive humidity sensor. In order to
keep the effects of external influences (e.g. solar radiation) as low as
possible, the sensors are located in a ventilated housing with solar
radiation protection.
Wind Speed & Direction
The wind sensor has no moving parts, which makes it virtually
maintenance free. Four ultrasonic sensors are used to continuously
collect measurements from all directions. The resulting wind speed and
direction are calculated from the measured run-time sound differential.
Barometric Pressure
Absolute air pressure is measured using a built-in capacitive MEMS
sensor.
Precipitation
Doppler Radar (600 Model)
Precipitation is measured by a 24 GHz Doppler radar, which measures
the drop speed of an individual drop of rain or snow. Precipitation
quantity and intensity are calculated from the correlation between drop
size and speed. The difference in drop speed determines the type of
precipitation (rain/snow).
The Doppler Radar sensor is able to sense (measure) rain drop size
between 0.3 mm and 5.0 mm. The sensor responds quickly with a
resolution of 0.0004 inches (0.01 mm).
Tipping Bucket Rain Gauge (601 Model)
Precipitation is measured by the tipping spoon and tipping bucket
process. The flexible tipping bucket allows a 0.2mm or 0.5m resolution of
the rainfall.
Compass
The integrated electronic compass can be used to check the north-south
adjustment of the sensor housing for wind direction measurement. It is
also used to calculate the compass corrected wind direction.
Columbia Weather Systems, Inc.

___________________________________________________________________
Solar Radiation (Model 501 Only)
Pulsar Weather Station model 501 integrates a Kipp+Zonen CMP3
thermopile sensor which measures the solar energy that is received from
the total solar spectrum with a 180 degrees field of view. The output is
expressed in watts per meter squared.
Rated ISO 9060:1990 Second Class, it is intended for shortwave global
solar radiation measurements in the spectral range from 300 to 2800 nm.
The thermopile detector measures irradiance up to 2000 W/m² with
response time <18 seconds and typical sensitivity 10 µV/W/m² that varies
less than 5 % from -10 ºC to +40 ºC.
Ventilation Fan:
To provide more accurate temperature and relative humidity
measurements the Pulsar sensor utilizes an airflow fan through the
sensor housing. (Excludes Pulsar 200).

SECTION 2: PHYSICAL
DESCRIPTION
Pulsar Sensor Transmitter
The Pulsar Sensor Transmitter is an all-in-one sensor available in five
unique models. Depending on the model, each device includes a
different combination of sensors for measuring a variety of parameters.
All of the Pulsar sensor transmitters utilize an integrated electronic
compass to orient the sensor housing and automatically correlate wind
direction.
Each model is equipped with a heater to prevent the effects of ice and
snow during winter operation. The heater is designed to maintain a
constant temperature to reduce the accumulation of ice and snow on the
wind sensor and the Doppler radar precipitation sensor where applicable.
The Pulsar weather station (excluding the 200 model) also includes a
temperature sensor and a relative humidity sensor inside of a ventilated
housing with radiation protection to reduce the effects of solar radiation
exposure. A ventilation fan provides air flow circulation through the
sensor housing for higher accuracy temperature and relative humidity
readings.

The function of the rain gauge will be significantly influenced by pollution
of the funnel or the tipping bucket mechanism. Routine inspection and
cleaning, if required, is recommended. The tipping bucket should be kept
free of debris, leaves, dust, dirt, pollen, etc.
Only clean when obviously polluted; avoid moving the tipping mechanism
to prevent false tips.
Best practice is to disconnect the sensor cable when cleaning to avoid
faulty precipitation amounts. Use water and a soft cloth for cleaning.

Installing the Pulsar Sensor Transmitter
Site Selection:
Finding a suitable site for the sensor transmitter is important in obtaining
representative ambient measurements. The site should represent the
general area of interest.
The sensor transmitter should be installed in a location that is free from
turbulence caused by nearby objects, such as trees or buildings.
Ensure the Pulsar 600 sensor is not installed near other devices that
may be transmitting at 24GHz; measurement error may occur.
WARNING: To protect personnel (and the device), a lightning rod should
be installed with the tip at least 40 inches (one meter) above the sensor
transmitter. The rod must be properly grounded, compliant with all local
applicable safety regulations.
Installing the Mast
There are three acceptable methods for mounting the mast to a roof or
building structure: Sloped roof mounting, flat roof mounting or wall
mounting. See Optional Sensor Mounting Hardware for more
information.
Location
Do not attach the sensor transmitter to a radio transmitting mast or
tower.
Select a mounting location that will allow the sensor cable to be routed
away from other data cables to avoid interference. Do not mount sensors
close to power lines. For normal roof mounting, the recommended
minimum distance from power lines is 25 ft. (8 m). Use extreme caution
when working close to power lines.
Mounting Method
Choose the appropriate mounting method for the installation and obtain
any necessary mounting hardware. Refer to Optional Sensor Mounting
Hardware section for information on optional sensor mounting hardware
and accessories which are available from the factory.
If the mounting hardware is not obtained from the factory, be certain to
use metal parts which are plated or galvanized to assure maximum
longevity.
Secure the mast to the roof, using guy wires with sufficient tensile
strength or to building wall using a wall-mount hardware kit.

____________________________________________________________________
Routing Cable
Use plastic tie wraps to secure the cable to mast, particularly at the mast
base. Tighten the tie wraps securely and clip off any excess length with a
wire cutter tool.
Once the Pulsar sensor transmitter has been placed, route the cable
back to the Interface Module or weatherproof enclosure.
CAUTION: There may be electric wires in the wall. When routing cable
through walls, we recommend that you shut off the electricity in the
room(s) where you are drilling.
Any mast or tower should always be properly earth grounded to minimize
electrical storm damage. The use of a properly grounded metal mast or
tower, however, does not insure protection from electrostatic discharge.
These items could become electrically charged resulting in damage to
the sensors and/or console. This could damage the system in the event
of an electrical storm.
Note: If the standard 50 ft. cable provided with the sensor transmitter is
not long enough, it may be extended by splicing on an appropriate length
of 22-gauge, stranded, seven conductor shielded cable with the same
color code. When cutting and splicing, insure good contacts, proper color
coding of the terminal leads, and a good seal. (A good solder splice, and
water proof insulation are essential; merely twisting the respective wires
together is not adequate.) Additional cable (Part No. 81547) is available
from the factory.

North Alignment – Integrated Electronic Compass
The integrated electronic compass will automatically correct the wind
direction. To compensate for the difference between True North and
Magnetic North the Magnetic Declination can be entered into the
MicroServer. Please see the MicroServer user manual for more
information.
Manual North Alignment (Optional Procedure)
The Pulsar sensors are configured to utilize the integrated electronic
compass to automatically align the sensor to magnetic north. Manual
north alignment is not needed unless the electronic compass is disabled.
In order for the wind direction to display correctly, the sensor must be
aligned to True North. The sensor has a number of directional arrows for
this purpose.
Wind direction can be referenced to true north, which uses the earth’s
geographic meridians, or magnetic north, which is read with a magnetic
compass. The magnetic declination is the difference in degrees between
the true north and magnetic north.
Columbia Weather Systems, Inc.
44
Pulsar Weather Station
____________________________________________________________________
North Alignment
1. If the sensor is already installed, first loosen both nuts evenly until you
can turn the sensor easily.
2. Using a compass, identify North and fix a point of reference on the
horizon.
3. Position the sensor in such a way that the South and North sensors
are in alignment with the fixed point of reference in the North.
4. Tighten both nuts. Once the sensor transmitter is aligned to north, the
transmitter can be removed from the mounting adapter without losing the
north orientation.

Glossary
Aspirating Radiation Shield
A device used to shield a sensor such as a temperature probe from
direct and indirect radiation and rain while providing access for
ventilation.
Barometric Pressure
The pressure exerted by the atmosphere as a consequence of
gravitational attraction exerted upon the “column” of air lying directly
above the point in question.
Celsius Temperature Scale
A temperature scale with the ice point at 0 degrees and the boiling point
of water at 100 degrees.
Dew Point
The temperature to which a given parcel of air must be cooled at
constant pressure and constant water-vapor content in order for
saturation to occur. When this temperature is below 0°C, it is sometimes
called the frost point.
Density Altitude
Density altitude is a meteorological variable that is important to pilots,
especially during the summer. The density altitude is the altitude in a
standard atmosphere where the density is the same as the given
atmospheric density. During a hot muggy summer day, a pilot begins
take off from an airport with an elevation of 2500 feet. Because of the
warm temperature and the moisture in the air, the airplane has to work
as if it was taking off at an airport at an elevation of 6000 feet resulting in
the plane needing more power and a longer roll down the runway to take
off.
Fahrenheit Temperature Scale
A temperature scale with the ice point at 32 degrees and the boiling point
of water at 212 degrees.

Global Radiation
The total of direct solar radiation and diffused sky radiation received by a
unit horizontal surface. Global radiation is measured by a Pyranometer.
Heat Index
The heat index or apparent temperature is a measure of discomfort due
to the combination of heat and high humidity. It was developed in 1979
and is based on studies of evaporative skin cooling for combinations of
temperature and humidity.
Pyranometer
It measures the combined intensity of incoming direct solar radiation and
diffused sky radiation. The Pyranometer consists of a radiation-sensing
element, which is mounted so that it views the entire sky.
Relative Humidity
Popularly called humidity. The ratio of the actual vapor pressure of the
air to the saturation vapor pressure.
Sea Level Pressure
The atmospheric pressure at mean sea level, either directly measured
or, most commonly, empirically determined from the observed station
pressure.
In regions where the earth’s surface pressure is above sea level, it is
standard observational practice to reduce the observed surface pressure
to the value that would exist at a point at sea level directly below.
Solar Radiation
The total electromagnetic radiation emitted by the sun. 99% of the sun’s
energy output falls within the wavelength interval from 0.15 microns to
4.0 microns, with peak intensity near 0.47 microns. About one-half of the
total energy in the solar beam is contained within the visible spectrum
from 0.4 to 0.7 microns, and most of the other half lies near infrared, a
small additional portion lying in the ultraviolet.
Wind Chill
That part of the total cooling of a body caused by air motion.

Tables and Formulas
Wind Chill Chart
In 2001, NWS implemented an updated Wind chill Temperature (WCT)
index. The change improves upon the former WCT Index used by the
NWS and the Meteorological Services of Canada, which was based on
the 1945 Siple and Passel Index.
In the fall of 2000, the Office of the Federal Coordinator for
Meteorological Services and Supporting Research (OFCM) formed a
group consisting of several Federal agencies, MSC, the academic
community (Indiana University-Purdue University in Indianapolis (IUPUI),
University of Delaware and University of Missouri), and the International
Society of Biometeorology to evaluate and improve the wind chill
formula. The group, chaired by the NWS, is called the Joint Action Group
for temperature Indices (JAG/TI). JAG/TI's goal is to upgrade and
standardize the index for temperature extremes internationally (e.g. Wind
chill Index).
The current formula uses advances in science, technology, and
computer modeling to provide a more accurate, understandable, and
useful formula for calculating the dangers from winter winds and freezing
temperatures.
