Using ESM as a leak locator unit

Application

The ESM “RadMan” is used to detect leaks in
waveguides.

Preparation

⇒

Slide the yellow absorber cap over the
battery compartment.
The “narda” marking is no longer visible.
The clip should point to the LED side.

⇒

If required: Screw the extension rod on to
the absorber cap.
