Cylinders of working gas traceable to NIST-SRM's (called EPA Protocol Calibration Gas) are
also commercially available (from sources such as Scott Specialty Gases, etc.).
7.9 Special Calibration Requirements for Dual Range or
Auto Range
If Dual Range or Auto Range is selected, then it should be calibrated for both Range1 and Range2
separately. Pressing CAL key will prompt #1 and #2 keys for Range1 (Low Range) or Range2 (Hi
Range) calibration selection. Select desired range number and press ENTR to proceed to the
calibration. Once Range# is selected, the display will show Test Measurements and SO
concentration for the corresponding Range#. You must enter expected SO
separately per Table 7-3 procedure for each Range #.
For zero calibration allow zero gas through the sample port and proceed to manual zero calibration
procedure per Table 7-2, step 2 through step 4. After zero calibration is set, switch to span SO
to continue for span calibration procedure per Table 7-4 step 2 through step 4. Press EXIT to exit
from the current Range.
Repeat above procedure for other Range # by pressing CAL key and selecting Range # as described
above. Enter once again corresponding SO
zero/span calibration for other Range # selected.
