EKO INSTRUMENTS CO., LTD. UV-B Radiometer MS-212W Instruction Manual Ver. 2
1. Installation Location
In order to obtain representative measurements from spectroradiometers, several criteria with respect to
setup and mounting of the instruments have to be considered:
Select a mounting position which it is free from obstructions at 5°above horizon.
Avoid surrounding towers, poles, walls or billboards with bright colors that can reflect solar radiation onto
the spectroradiometer.
The setup location should be easily accessible for periodic maintenance (quartz dome cleaning,
desiccant replacement, etc.).
2. Installation Procedure
MS-212W Sensor Installation
1) Make sure the fixing holes are already
prepared on the mounting base for the
MS-212W. Refer to the image on the right
for the fixing holes pitch.
2) Place the MS-212W with drying cartridge
facing towards South (connector facing
towards North). (In case of installation in
southern hemisphere, drying cartridge
should face towards North and connector
towards South)
If the connector is exposed to the sun
direction, the connector temperature will
increase and will lead to output error by
thermoelectric power.
3) Remove the Sun Screen.
When removing the Sun Screen, always turn about 60 degrees angle in the Sun Screen in clockwise
direction. Turning in anti-clockwise direction may loosen the quartz dome holder.
When lifting up the MS-212W, always hold the metal part of the body instead of just the Sun Screen part.
Holding just the Sun Screen part may lead to breaking the Sun Screen and drop the instrument.
4) In order to properly install the MS-212W sensor surface in horizontal position, adjust the level by using
the 2 leveling screws.
5) Put the 2 bolts (M6 x 75mm) through the fixing holes (see drawing) on the MS-212W and tighten the
MS-212W with these 2 screws equally.
Make sure the MS-212W is securely fixed or it may lead to unexpected accidents by the instruments
dropping in case of earthquake and so on.
6) Place the Sun Screen, which was removed in Step 3, back on the MS-212W in clockwise direction again.
Installing Converter
Avoid installing the Converter in an environment which is high temperature and high humidity.
The Converter should be installed indoor as it is not designed with waterproof function.
