How to Perform Multi-Channel Measurements
Phase readings do not shift by ninety degrees when integrating
between acceleration, velocity, and displacement. Phase
measurements are intended to be used in comparison to
diagnostic charts.

Special Considerations When Taking Multi-Channel Measurements
Consider the following when connecting sensors for multi-channel analysis:
• For a single channel display connect the sensor to CH1.
• For a 2 channel measurement connect sensors to CH1 and CH2.
• For a 3 channel measurement display when using a tri-axial sensor, connect the
sensor cable to CH1.
• For a 3 channel measurement when using separate sensors, connect a single
sensor to CH1 (displays as the top trace), connect the CMAC 5079 cable (sold
separately) to CH2; connect the sensor for channel 2 to connector A - and the
sensor for channel 3 to connector B.
• For a 4 channel measurement, connect a CMAC 5079 cable to CH1 and CH2. The
CMAC 5079 connected to CH1 should have the sensor for channel 1 attached to
connector A and channel 4 attached to connector B. The CMAC 5079 cable
connected to CH2 should have the sensor for channel 2 attached to connector A
and the sensor for channel 3 attached to connector B.
