4. Introduction
The Grating Spectroradiometer MS-713 is developed for measuring solar spectrum outdoor, and it is a unique all
weather concept instrument which can be used in various fields such as meteolorogy, photovoltaic and agriculture.
Solar spectrum changes various ways depending on the season, the time of day, and the regional air mass and
atmospheric composition. In response to changes in the spectrum, the power generation performance of
multi-junction solar cells such as concentrating solar cells significantly change, and the growth conditions of crops
differ. Detailed and quantitative understanding of the sunlight spectrum using a spectroradiometer makes it
possible to analyze the relationship between device performance, crop growth, etc. and the spectrum.
MS-713 can measure the near infrared region in the wavelength range of 900 nm to 2,500 nm.
By using MS-713 in combination with MS-711, it is possible to seamlessly measure a broad wavelength range from
300nm to 2,500nm (MS-711 has a visible/ near infrared region between wavelength range of 300nm and 1,100nm,
MS-713 measures the near infrared region from wavelength 900nm to 2,500nm.)
MS-713 has succeeded to control the temperature of the spectrometer at constant to suppress the temperature
change in spectrometer, which will greatly affects the measurement uncertainty, allowing maintaining a high
performance over a wide operation temperature range. In addition, MS-713 is has better resistances to mechanical
vibration and external force compared to optical fiber type spectrometer due to optimal designs of diffuser and
optical components. Therefore, it provides improved stability for continuously measuring outdoor, and excellent
robustness in transportation for cyclic measurements.
MS-713 have a separate power supply and can be controlled through RS232 / 422 by a PC or data logger. The PC
software provide different fuctions for operating, data management and visualisation.

4-1. Main Features
1. All-Weather
Using our technology cultivated through the design, manufacture and sale of weather observation equipment
used outdoors such as pyranometers, we also have our grating spectroradiometers as all-weather products.
MS-713 can be used for a long-term outdoor measurement.
2. Wide Measurement Range
By combining the MS-711 (300nm to 1,100nm) and MS-713(900nm to 2,500nm), it is possible to measure a
wide wavelength range from 300nm to 2,500nm.
3. Operating Software
The operating software has different measurement functions, to make either a “single measurement” or
“scheduled measurement” which takes periodical measurements every day.
This software allows to display multiple spectral data in one graph, as well as to review details of one spectral
data and so on.
These software have the functions of resampling and saving the wavelength interval of spectrum data every 1
nm, automatically calculating various operation values, and combining with the spectrum data of MS-711 and
MS-713.

5-2. Setup Location
1. Location
In order to obtain representative measurements from spectroradiometers, several criteria with respect to
setup and mounting of the instruments have to be considered*:
The ideal mounting position for the spectroradiometer is a location which has a full hemispheric field-of-view
without any obstructions (such as buildings, trees, and mountain). In practice, it might be difficult to find such
locations. Therefore, some practical recommendations on how to minimize undesired effects of reflecting or
obstructing surfaces are given next:
•Select a mounting position which it is free from obstructions at 5°above horizon.
•The setup location should be easily accessible for periodic maintenance (quartz dome cleaning,
desiccant replacement, etc.).
•Avoid surrounding towers, poles, walls or billboards with bright colors that can reflect solar radiation
onto the spectroradiometer.
2. Installing at Horizontal or tilted Positions
(1) Prepare Installation Base
Check the installation base where the MS-713 has to be mounted and make sure it has two fixing holes
with the appropriate pitch. The pitch sizes of the fixing holes are as follows (in mm):
Table 5-3. Fixing Hole Pitch and Bolt Size

Pg. 14
(2) Setup the MS-713 Sensor
Setup the sensor with the signal cable connector facing the nearest Earth’s pole.
In the Northern hemisphere, the connector should be orientated North, in the Southern hemisphere,
the connector should be orientated South.
(3) Leveling
Adjust the sensors in a horizontal position by using the 2 leveling screws and observing the air
bubble in the spirit level while manipulating the leveling screws. The instrument is leveled
horizontally if the air bubble is in the center ring. Once the instrument is leveled properly, fix the
instrument with mounting bolts.
In case the sensor is mounted on a tilted plane, preferably the sensor is mounted on the leveling
screws to thermally isolate the sensor form the mounting platform.
If the sensor is not leveled properly, the readings are affected by cosine and azimuth errors.
Periodically check the spirit level and adjust its position if necessary.
(4) Adjust Height
To take measurements by setting up the MS-713 side by side, the sensor surface must be adjusted
to the same height level.
(5) Cover
Place the Cover on the instrument and fasten with 3 screws (M3).
(6) Connect Sensor Cable
Connect the sensor cable connector to the sensors and the Y-terminals to the terminal block of the
power supply according to the table below.
Make sure the sensor connector part is securely connected so that moisture will not enter the
connector. Also fasten the cable with such as band strip so that it will not be blown by wind
If the sensors are setup on Sun Tracker, make sure to have sufficient length of cable for rotation
movement.
Use + screw driver to connect the cable to lug terminals on the power supply, make sure the cable
numbers and the terminal numbers match.
NOTE: The power supply can’t be used in an unprotected outdoors environment, as it can only be
used in a dry environment.

connect the other end of power cable to the socket properly. Make sure that provided power is
AC100-240V, 50/60Hz, 50VA.
(8) Connect Communication Cable
Connect the PC COM port and the RS-232C connector at the back of the power supply with
RS-232C cable. When connecting, insert the connector which has ferrite core to the power supply.
