ULTRASONIC EMITTER

The Ultrasonic emitter is used with the Marksman II to locate
leaks in walk-in coolers/freezers, wall and ceiling joints, around
doors, windows, body seals, rubber moldings, ducts, etc. The
emitter produces the precise frequency detected by the Marks-
man II. By placing the emitter in a sealed area and scanning the
exterior of this area, any signal escaping from the sealed area will
be indicated by the Marksman II. A flaw in the seal can quickly and
accurately be pinpointed.
1. Turn on the emitter's power switch. The LED will illuminate to
indicate it is operating.
2. Splace the emitter into the area to be tested completely.
3. Set the "Sensitivity" control of the Marksman II to maximum.
4. Scan the exterior area for the suspect leaks.
5. To pinpoint leaks, see General Information on pages 5-6.
6. When using the emitter with headphones plugged into the
Marksman II, the instruments will indicate ultrasonic
disturbances through a variable-pitch tone.
