• It is not allowed to use the product in explosive areas.
• observe the national regulations before/during operation.

Remarks

• It is not allowed to disassemble the product.

ATTENTION!
Measurement values can be affected by malfunction!
The product must be used properly and frequently maintained, otherwise it may lead to wrong measurement values, which can lead to wrong results.

• Avoid condensation on the leak detector element as this will affect the accuracy enormously.

Storage and transportation

• Make sure that the transportation temperature of the leak detector is between 20°C… 50°C.
• For transportation it is recommended to use the packaging which comes with the leak detector.
• Please make sure that the storage temperature of the sensor is between 10°C… 50°C.
• Avoid direct UV and solar radiation during storage.
• For the storage the humidity has to be <90%, no condensation.

Application

• The PCE  LDC 8 is a leak detector for pneumatic systems. When gases are leaking through tubes and tanks an ultrasonic sound is produced which can be detected by PCE LDC 8 even from several meter distance.
• The PCE LDC 8 transforms these inaudible signals into a frequency which can be easily heard by using the supplied noise isolated headset. In unpressurised systems an ultrasonic tone generator can be used whose sound will leak through small openings.
• The integrated laser pointer helps to spot the leak from distance.
• The PCE LDC 8 leak detector is not developed to be used in explosive areas. For the use in explosive areas please contact the manufacturer.
• The PCE LDC 8 leak detector is mainly used in compressed air systems in industrial environment.

Features

• Leak detection in compressed air, refrigerants, simple of any gas.
• Insulation test of doors and windows.
• Detection of partial electrical discharges causing damages on insulations.
• Can be used in noisy environments.
• Included laser pointer helps to locate the leak.
• Included display, showing the level of the leak.

 Operation

Please make sure that all components listed below are included in your package.

Qty Description

•  PCE LDC 8 leak detector
• Sensor unit
• noise isolated headphones
• focus tube incl. focus tip
• Cable from instrument to sound probe
• Battery charger
• Transport case
• user manual

Remark
The sensor unit can be unplugged from the main instrument by pulling the unit out of the holder. A separate coiled extension cable is used to connect the sensor to the main unit

Operating Principle
Air leaks produce wide ban d ultrasounds in the range of 20… 80 kHz. The higher the frequency the more energy it contains. But higher frequencies can not be transported in air that far. That i s why the leak detector operates at a centre frequency of 40 kHz which compromises an optimum um between energy and distance. Frequencies below and above are cut in order to minimize the noise level.

Operating Procedure
The following steps explain the procedure of an appropriate use

1. Press the Power button.
2. The Display of the PCE LDC 8 look like the picture on the left side.
   • The laser pointer is off.
   • The Display will show you
   • The battery level.
   • The segments green till red.
   • User can change the sensitivity with the wheel .
3. To activate the laser, please
4. press the button which is shown
5. on the left side.
6. Point with the laser at an assumed leak. The display will show the level of the leak.
7. To find the exact location of the leak screw the focus tube and the focus tip on the sensor.
8.  Scan with the focus tip the roughly location till the exact location is found.
9. For difficult attainable location you can use the separate coiled extension cable.

Electrical connection
Either the headphone or the charger can be connected to PCE PCE-LDC 8 at a time time.

Remark
If the instrument has not been used for more than 2 months, the battery might be over discharged. Connect the battery charger an and wait about 2 2-3 minutes until the display can show you the actual battery status.

 Maintenance

To clean the sensor and its accessories it is recommended to use moist cloth only.
ATTENTION!
Do not use isopropyl alcohol to clean the sensor and its accessories!

Disposal
