Transmitter Configuration and Use: Series 1000 and 2000 Transmitters 63
Required Transmitter Configuration continued

6.6.5 Configuring mode
If both Channel B and Channel C are configured as frequency outputs, they function
as a dual pulse output. In dual pulse mode, the second frequency output can be
phase-shifted either 0°, 180°, +90°, or –90°, or set to Quadrature (the default). See
Figure 6-11.
In Quadrature mode, Channel C:
• Lags Channel B by 90° during forward flow.
• Leads Channel C by 90° during reverse flow.
• Is driven to zero during a fault condition.
Quadrature mode is used only for specific Weights & Measures applications where required by law.
Note: If only one channel is configured as a frequency output,
Frequency Output Mode is set to
Single and cannot be changed.
