and malfunction of product.
1) Use provided adaptor. When using other
adaptors, make sure to use proper rating
and standard product. It may causes
damage and measurement error.
6 Calibration
‘M’ : Manual re-calibration during 10 minutes
in fresh air (or 400ppm CO2gas) - MCDL
‘A’ : Automatic calibration mode – ACDL
(Monthly auto calibration , For HVAC, ventilation usage)
2) Do not disassemble, modify or repair the
products.
3) Avoid shock, vibration, direct sun light.
None: Factory calibration operation mode
(for Green house and other Agricultural
usage)
‘A’ : Automatic calibration mode – ACDL

ELT-WSD program is developed for customer to change the CO2
Alarm range of MB-350 with
USB 2.0 interface of PC.
Execute "ELT_WSD_MB-350.exe" with mini-USB cable connected
between PC and MB-350, of which 12V Power (12V AC/DC Adapter)
should be provided.
