Perform a Distance‑to‑PIM measurement with a known PIM marker in place. Remove that PIM marker and perform the same measurement again. Then compare measurement traces to determine a PIM location.
DTP/DTP Trace Overlay Example
1. Set your PIM Master measurement type to Distance‑to‑PIM by pressing Measurements > Distance‑to‑PIM.
2. Set up DTP measurement parameters.
3. Press Measurements > Test.
4. When the measurement is completed, press Shift then Trace (5).
5. In the Trace menu (see Figure: Trace Menu – Distance‑to‑PIM), press Copy Active Trace to Overlay, When an active trace is copied to overlay, the Trace Overlay submenu key is automatically toggled to On (if not already On).
When the trace has been copied to overlay, the trace color immediately changes to the color that has been set in the Select Color choice box (see Figure: Overlay Trace Color Selection).

The active trace is displayed along with the stored trace, and markers are automatically placed on the peaks. The marker table displays the relative distance between peaks. Refer to Marker Menu and the marker menu for additional information. To view the table, toggle the Marker Table submenu key to On or to Large.
