IMPORTANT NOTES BEFORE USE

✓ While connecting your SV 200A to a PC by the SC 256A cable, first insert the lemo plug into the

instrument’s MULT. I/O socket and then the USB plug into the PC!

✓ Monitoring station should not be stored for a long time with discharged Li-Ion batteries. Storing with

batteries in discharged condition may damage them. If so, warranty for Li-Ion battery is void.

✓ If Monitoring station is planned to be stored for a long period of time, it is recommended to charge

its battery to 60% capacity. The battery should be charged at least once per 6 months.

✓ Before installing the station at the measurement site, make sure that the protective caps on the four

anti-bird spikes are removed. It is recommended to use the protective caps during transportation
and storage or other operations with the instrument like, laboratory calibration, etc. to avoid
personal injury.

✓ Tripod or pole with 3/8” thread is not recommended for permanent installation.
✓ The windscreen influences the free-field characteristics of the instrument, therefore it is important

to check its condition regularly. In the case of visible degradation of the foam surface it must be
replaced by the new one.

✓ Even though the SB 274 power supply unit has a high IP index (Ingress Protection), it is still not

recommended to leave it on the ground for safety reasons. Good practice is to mount it on the pole
or mast.

✓ While opening the control panel flap the coin-operated screw should be loosened using, for

example, a coin and then unscrewed with fingers until it stops. Opening the flap with the screw left
in the intermediate position may damage the varnish of the casing.

✓ Maximum sound pressure level that can affect the microphone without destroying its membrane is

146 dB.

2.5 ANTI-THEFT PROTECTION

There is a special swivel eye in the kit that can be used as anti­theft protection of your SV 200A with the use of locking cable.
It is necessary to screw it to the base of the sleeve with the
special key.

2.6 WINDSCREEN PROTECTION

The SA 209 foam reduces the effect of wind on measurement results.

Note: The windscreen influences the free-field characteristics of the instrument, therefore it is
important to check its condition regularly. In the case of visible degradation of the foam surface it
must be replaced by the new one.

During continuous usage, the SA 209 foam is exposed to different weather conditions with possibility of
causing mechanical damage to the foam’s structure. Therefore, it is recommended, at least once a quarter
(3 months), to check the condition of the foam by examining the surface for cracks by squeezing the foam.
If cracks or holes are observed, the SA 209 foam must be replaced.

The SA 209 foam must be replaced whenever squeezing it causes severing of small pieces of its surface.
Replacement of the foam windscreen should be performed according to steps 1 to 5 of Chapter 4.1 and

steps 8 to 12 of Chapter 2.3.

SV 200A User Manual

2.8 ASSEMBLING THE SP 275 WEATHER STATION ON THE MAST (OPTIONALLY)

SP 275 is mounted on a meteorological beam that can be
installed on the mast below SV 200A. The distance from the
beam to the SV 200A device should be as great as possible, but
it is limited to the length of the SC 209 cable.

Note: If your Vaisala Weather Transmitter is equipped

with the wind sensor, then it is critical to set the correct sensor
orientation. The North direction is marked at the bottom of the
weather transmitter. Use real-life compass or mobile app to
determine North direction.

2.9 FINISHING

Attach cables to the mast and the
optional meteorological beam. Use
some band clips at intervals not greater

than 50 cm (20”) on the mast and the

cable holders delivered with the kit
(Velcro fasteners) on the
meteorological beam. Lay the cables
so that they are loose at the ends. The
loose cable should hang a bit lower
than the connector to avoid
accumulation of rainwater.

Note: Fixation of cables is important because loosen cables may generate additional noise. As
an alternative way, wrap the cables around the mast.

In the end of installation connect the SB 274 power supply unit and switch on the station.

SV 200A User Manual

The internal battery is charged in a fully automatic cycle, when the instrument is connected to any external
power source. SV 200A charges itself regardless of whether it is turned on or off. The weather conditions
(i.e. temperature) are taken into account while charging to prevent any damage of the battery caused by
charging in too high or too low temperature.

Note: SV 200A is equipped with the mechanism which protects the internal Li-Ion batteries
from damage caused by critical discharge. When the battery is running flat, the instrument is
automatically switched off.

Note: SV 200A should not be stored for a long time with discharged Li-Ion batteries. Storing
batteries in discharged condition may damage them. If so, warranty for Li-Ion battery is void.

Note: If SV 200A is planned to be stored for a long period of time, it is recommended to charge
its batteries up to 60% of their capacity. Batteries should be charged at least once per 6 months.
