In addition to each channel having two ranges, each channel has two span
coefficients. There are two span coefficients so that each range can be
calibrated separately. This is necessary if the two ranges are not close to one
another. For example, the low NO range is set to 0–50 ppb and the high
NO range is set to 0–200 ppb.
By default, in the dual range mode, the analog outputs are arranged on the
rear panel connector as shown in
and pin connections. Dual range mode may be selected from the
Mode Select" on page 3-74.
