The Model 3600 Power Line Disturbance Monitor  typically refers to a diagnostic instrument used to track and record power anomalies that can disrupt sensitive electronics. Depending on the specific brand, the model can apply to several different voltage ranges. 

A Power Line Disturbance Monitor (like the 

Model 3600

) works by continuously sampling the incoming AC voltage waveform to identify deviations from an ideal sinusoidal wave.

Depending on which "3600" model you are using, the core operation differs:

1. Diagnostic Monitoring (Liebert/

Franklin 3600

)

These units are "passive" diagnostic tools. They do not change the power; they only watch and record it.

• Sensing: Probes or sensing leads are connected to the power lines (single or three-phase).

• Threshold Comparison: The device compares real-time voltage and current against pre-set limits (e.g., +/- 10% of nominal voltage).

• Event Logging: When a disturbance occurs—such as a sag (voltage drop), swell (voltage spike), or transient (fast noise)—the monitor "triggers." It captures the exact timestamp and the magnitude of the anomaly for later analysis in an event lo
