Kaman KDM-8206 - Manual (Page 8)

A special calibration record of this output can be provided upon request. No attempt is made to
linearize or otherwise adjust demodulator output for the calibration record; it is a record of the output
only.
3.4 Differential (Balanced) Output:
For industrial applications, high noise environments or long output cable lengths, an optional
differential output is available. This provides two opposite polarity voltage signals that can be
combined (summed) at a differential input to cancel noise and provide a higher signal. Output as high
as ±20 VDC is available differentially.
NOTE: Since this is true differential, grounding either side can cause failure.
To change the voltage output from single ended to differential (the difference between V+ and V-
Outputs); change the J7 jumper on the KDM-8206 Measuring Channel from positions 1 and 2 to
positions 2 and 3.
When installed in a Sub-Rack or Instrument Enclosure, the rack back panel PCB with a V- BNC
connector is required. The back panel PCBs does not include this connector unless requested.
