4.2.3 Wiring for Multiple-Circuit Measurement
• One 3169-20/21 unit can measure multiple circuits of the same
voltage system (same transformer).
• The wiring mode is common to all circuits.
• Measurements of the current channels will not be zeroed when
the device is not connected to the clamp-on sensor.
Single-phase 2-wire, 4circuits (1P2W X 4)
