Eco Sensors Ozone Controller Model OS-6 6
KWJ Engineering Instructions for Use, Rev. 1.2
Analog Output PPM Full-Scale Range Selection
Full-scale ranges for the 0-2 V and 4-20 mA analog outputs may be selected by adding
or removing up to three push-on jumpers on header J4, which is located on the back of
the display circuit board. Access this area by removing four screws from the display
bezel.
Jumpers A B C Full-Scale Range selected
OFF OFF OFF 0-2 PPM
ON OFF OFF 0-5 PPM
OFF ON OFF 0-10 PPM
ON ON OFF 0-20 PPM
ON OFF ON 0-50 PPM
ON OFF ON 0-100 PPM
OFF ON ON 0-200 PPM
ON ON ON 0-500 PPM
IMPORTANT NOTES:
This setting changes only the range of the analog output signal. The OS-6
display will always read 0.000 to 999.9 PPM, to accommodate a range of
currently available and future sensor modules.
The range of an OS-6 is limited by the sensor module. The OS-6 is shipped from
the factory with the Full Scale Range set to match the installed sensor module.
Higher ranges may be available on future sensor modules. Please contact Eco
Sensors for details.
