2.3.4 PMI Meter Port Selection Screen (Vector with Constant Power)
The Meter Port Selection Parameter Entry screen allows you to enter specific
information about what variables are to be output on the four PMI D/A channels (the
four meter ports on the PMI motherboard. See figure 2.8.
Table 2.4 lists the values that can be displayed on the PMI meter ports using the
Vector with Constant Power regulator. You must enter a Minimum Value and a
Maximum Value for each selection except when you select Port Not Used. The
Minimum Value is the value at which to output -10V. The Maximum Value is the value
at which to output +10V. The system software then places the units per volt on the
screen based on the Minimum/Maximum Values.
The Minimum Value must not be less than -32768. The Maximum Value must not be
greater than 32767. The Minimum Value must be less than the Maximum Value.
Note that the PMI meter ports have 8-bit resolution and are updated on the average of
every 1.0 milliseconds.
See the PMI Regulator instruction manual (S-3057) for more information about the
PMI meter ports. See section 3.7.2.1 of this instruction manual for information about
resolution of data.
