EC9830 CO ANALYZER OPERATION MANUAL
2-32 98307600 Rev. C-1
RANGE
Set upper range limit (in digits) to desired CO concentration. See section 2.6. This
value cannot be set above the OVER RANGE value.
OUTPUT TYPE
Setting must match the choice on the 50-Pin I/O board (if installed), current or
voltage.
CURRENT RANGE
Choices are 0-20, 2-20, and 4-20 mA.
FULL SCALE
X.XX%, a correction factor for full scale setting. Used when calibrating the analog
outputs.
ZERO ADJUST
X.XX%, a correction factor for the zero setting. Used when calibrating the analog
outputs.
OVER RANGE
Set to desired over-range value. This value cannot be set below the RANGE value.
See section 2.6. This is the alternate scale the recorder or DAS indicates when
over-ranging is enabled. (When 90% of the set range is reached, this automatic
range is effective. When 80% of the original range is reached, it returns to the
original range.)
OVER-RANGING
Set to ENABLED or DISABLED to turn the over-ranging feature on or off.
