PROCESSING MODES AND APPLICATIONS
As shown in Figure 7-28 as Out 1, dual mathematical function processing only operates on
the first processed outputs from the single-channel processings:
• DMF for Measurement Input Channels 1 & 2 operates on the first processed outputs of
Channel 1 and Channel 2.
• DMF for Measurement Input Channels 3 & 4 operates on the first processed outputs of
Channel 3 and Channel 4.
NOTE: The Dual mathematical function processing implemented on VM600 MPC4 cards
can be configured as X & Y MAX in order to use ISO 7919-1 method B to calculate
an S
max
value. See also 7.7 Smax measurement.
