Shenzhen dejiabao Electronics Co., Ltd. - LH probe manual
£Product instructions
1.When the product is kept clean after unpacking, clamp the needle with a tool and put the needle tube vertically into the sleeve. After fixing, use a shaft pressing tool to gently press down the sleeve from the top of the needle. The top of the needle tube is parallel to the top of the needle sleeve or the top of the needle tube is 0.3mm lower than the top of the sleeve.
2．When the probe is testing the product, the stroke of the needle is 1 / 2 ± 1% of the standard stroke when the needle is not working. Exceeding or below this standard will affect the product quality and working effect.
£Product storage and preservation methods
1．Dry in a cool place or put into a drying box and add a small amount of drying agent.
2.The environment in which the probe is stored must be kept clean and hygienic.
3.When the unpacked products are not in use, they should be put into the packaging box in time for storage.
£Precautions for product use
1．The probe and needle sleeve must match each other with the same brand.
2．When the probe is put into the needle sleeve, special flat pliers must be used to put it into the needle sleeve to prevent the deformation of the needle tube, so as to increase the resistance between the spring in the needle tube and the tube wall and increase the friction, then the pressure will increase, resulting in shorter service life of the probe and damage to the tested products.
3．The top of the needle tube of the probe and the top of the needle sleeve must be vertical (90 °) and the needle tube must be low into the needle sleeve, so as to avoid excessive needle stroke of the probe during operation, which will affect the service life and test effect of the probe.
4．Before putting the probe into the test rack, the probe must be kept clean and free of other sundries and dirt, so as not to cause head blackening during the test, hinder the normal operation of the probe and affect the test effect.
5．When the probe has been tested for 50000 times, it is recommended to use the special cleaner for LH probe.
6．The stroke of the needle and the needle tube has reached 1.8n elastic force when the total length of the needle is 1 / 2 when the needle is not working, and 2n (Newton) when the stroke is greater than 2 / 3 of the needle. Therefore, the total reduction exceeds the standard working range of the probe. Affect the life of the probe.
