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 HCl range is set to 0–5 ppm and the high
HCl range is set to 0–5000 ppm.
By default, in the dual range mode, the analog outputs are arranged on the
rear panel connector as shown in
Figure 3–5 . See Table 3–3 for channels
and pin connections. Dual range mode may be selected from the “ Range
Mode Select ” in the “ Service Menu ”, later in this chapter.
