Ultrasonic Emitter - TRACER PRODUCTS Marksman II Serie Manual Del Operador

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 Marksman 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 indi-
cated by the Marksman II. A flaw in the seal can quickly and accu-
rately be pinpointed.
1. Turn on the emitter's power switch. The LED will illuminate to
indicate it is operating.
2. Place the emitter into the area to be tested. Seal 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 instrument will indicate ultrasonic distur-
bances through a variable-pitch tone.
