8.6Special Calibration Requirements for Dual Range or Auto Range

If Dual Range or Auto Range is selected, then it should be calibrated for both Low Range (Range1) and High Range (Range2) separately. Pressing CAL key will prompt Low Range and High Range keys for Range1 (Low Range) or Range2 (Hi Range) calibration selection. Select desired range number and press ENTR to proceed to the calibration. Once desired range is selected, the display will show Test Measurements and SO2 concentration for the corresponding range. You must enter expected SO2 gas concentrations separately per Table 8-3procedure for each range.

For zero calibration allow zero gas through the sample port and proceed to manual zero calibration procedure per Table 8-2,step 2 through step 4. After zero calibration is set, switch to span SO2 gas to continue for span calibration procedure per Table 8-4step 2 through step 4. Press EXIT to exit from the current Range.

Repeat the above procedure for the other Range by pressing CAL key and selecting the Range as described above. Enter once again corresponding SO2 gas concentration for selected Range and continue zero/span calibration for the other Range selected.

M100AH with Zero/Span Valves option can be used to calibrate zero/span of the desired Range. Pressing CALZ (for zero) or CALS (for span) keys will lead to show Low Range and High Range the same way as CAL key except CALZ is dedicated for zero air calibration while CALS is dedicated for span gas calibration.
