CS Instruments Contents 1. 2. 3. 4. 5. Operating principle Technical data Scope of delivery Operation of instrument Typical applications Important information The operating instructions must be read in full and carefully observed before starting up the device. The manufacturer cannot be held liable for any damage which occurs as a result of non-observance or non-compliance with this manual.
CS Instruments Safety instructions Must be read before starting up the device! Warning: • • • Switch on instrument without head set on. Monitor the display that there are only green bars shown. In case of yellow or red bars, reduce sensitivity by turning the sensitivity wheel.
CS Instruments Air leaks produce wide-band ultrasounds in the range of 20 ... 80 kHz. The higher the frequency the more energy it contains. But higher frequencies can't be transported in air that far. That's why LD 300 operates at a centre frequency of 40 kHz which compromises an optimum between energy and distance. Frequencies below and above are cut in order to minimize the noise level. Scope of delivery Description Order No.

CS Instruments Operation of instrument Figure A: LD 300 operation diagram - LD 300 is switched on - LCD all segments on for 2 sec.
CS Instruments Figure B: LD 300 headphone and charger connection diagram Figure C: Battery charging operation diagram Attention: If the instrument hasn't been used for more than 2 months, the battery might be over discharged. You should connect the battery charger and wait about 2-3 minutes until the display can show you the actual battery status. Applications With all operating equipment, most leakage and electrical problems produce a broad range of sound.
CS Instruments In addition, as slight changes begin to occur in mechanical equipment, the directional nature of ultrasound allows these potential warning signals to be detected in time, before actual failure occurs. Typical applications of LD 300 are compressed air leak detection, vacuum leak detection, steam trap inspection and detection of arcing, tracking and corona in electrical equipment.
CS Instruments characteristic noise of a leak. Go closer to identify the location exactly. Adjust the sensitivity when necessary. To detect very small holes the focus tube and the focus tip can be sticked onto the sensor unit. In applications where LD 300 is too bulky for a close up detection, the sensor unit can be removed from the main unit. In the scope of delivery there is an extension cable which can be connected between sensor and main unit.
