Figure 2.8 shows the values that can be displayed on the PMI meter ports. These values are
described in detail in chapter 3. You must enter a Minimum Value and a Maximum Value for each
selection except for those marked as Port Not Used. The Minimum Value is the value at which to
output -1 0V The Maximum Value is the value at which to output + 1 OV. 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 every 1 .O millisecond. Refer to the Power Module Interface Rack
instruction manual for more information about the PMI meter ports. Refer to section 3.6.2.1 for
information about resolution of data.
