1,Principle of detection:put the wet sponge on the coating,the liquid infiltrate into the pinhole, turn on the circuit with the substrate, HD-104 detects the circuit automatically, then make a sound to alarm. Three voltage indicator turn on at the same time, then the pinhole will be detected. User can mark at the pinhole for future repair.
(3)——probe stick terminal；
(8)——low voltage indicator；
(14)——grounding/three core plug wire；
3,structure description:the instrument consists of host, grounding wire and sponge brush.
(1)host: equipped with integrated control circuit, lithium batteries, sound and light alarm device and so on；
(2)grounding wire: connect with the substrate of detected target；
(3)sponge brush: connect with the surface of detected target after soaking.
1,read up the instruction of instrument, make clear the functions of each part, the specific names are shown in structure description.
(1)voltage switch: adjust the output of three voltage to adapt to different anti-corrosive coating；
(2)power switch: turn on/off the power；
(3)9V indicator: when the light is on, then output voltage value is 9V；
(4)67.5V indicator: when the light is on, then output voltage value is 67.5V；
(5)90V indicator:when the light is on, then output voltage value is 90V；
(6)low voltage indicator: please charge；
(7)grounding charger: connect the grounding wire to charger；
(8)probe stick terminal: connect the probe stick；
(9)rubber retainer: protect the instrument when falling；
(10)light alarm zone: three voltage indicator light at the same time to alarm when there is leak point detected；
(11)handle: hold the handle when detecting；
(12)probe stick: connect the sponge brush with host；
(13)sponge brush: connect with the surface of detected material after soaking in the conductive liquid or water;
(14)grounding wire: connect the grounding/three core plug with the substrate of detected material；
(1)assemble the host, probe stick, sponge brush and grounding wire according to the HD-104 instruction, use powerful magnet to adsorb on the bare surface of metal tube wall, then use grounding wire clip to clamp the magnet. User can also connect the grounding wire clip with the bare surface of metal tube wall.
(2) use conductive liquid(water) to wet sponge brush.
(3)contact the wet sponge brush with the other side of bare surface, the instrument should send out light and sound alarm signal which mean that leak detector is ready. Move the wet sponge on the surface of anti-corrosive coating closely when detecting leakage. According the alarm signal to find the leak points, do some marks at the pinhole for future repair.
(4)The surface of the anticorrosive coating should be dry before leak detection. If the coating is in an environment (such as salt spray) where an electrolyte can be formed on the surface, the coating surface should be washed and dried before leakage detection. During leak detection, the electrolyte shall be at least 13mm away from the end of the metal pipe or the exposed metal surface.
1,if leak detector will not be used for a long time, user should fully charge the batteries; charge the batteries for each 3~6 months.
2,for not affecting the effect of leak detection, grounding wire should have good contact with the metal part of detected material.
3,sponge brush which is made of PVA uses Germany technology, has super absorbent and toughness. If the sponge has become harden before using, please put the brush in the water around 2~3 minutes to use(water temperature should be under 80 degree). Do not insolate. Keep the brush wet for each time use in order to not influence the detection. Put the brush in a sealed bag for next time use.
