Ametek 7124 Instruction Manual page 119

Since the instrument is now generating two sets of outputs (one for each of the
reference signals) there are more output display choices in this mode than in single
reference mode, and these are listed in table 5-2. The outputs corresponding to the
two references are identified by the suffices "1" and "2" respectively.

Table 5-2, Output Display Choices - Dual Reference Mode
The additional outputs may be stored to the curve buffer.
When in dual reference mode, the user-defined equations, specified on the Output
Equations menu (see section 5.3.08), allow the selection of the additional outputs as
variables. For example, it is possible to calculate a value proportional to the ratio of
the X channel output to that of the X
