ND-600B double probe needle detector maintenance requirements

Because the ND-600B dual-probe needle detector is a highly sensitive instrument, it has relatively strict requirements for environmental and machine maintenance. Therefore, after using for a period of time, in order to ensure normal use, it is necessary to clean the conveyor belt part and other easily stained parts regularly every day.
Conveyor belt surface cleaning: Note that the sensitivity of the needle detector should be adjusted to the lowest level before cleaning. If the needle detector has B/C mode, please adjust the needle detector to C mode to avoid the sensitivity being too high and affecting the next cleaning. jobs. Then straighten the towel and press it tightly on the surface of the conveyor belt, start the machine, and let the machine run for more than five rounds (in order to clean the surface of the conveyor belt, the method can be applied flexibly), then wash the towel and wring it out. Repeat this step again to wipe the conveyor belt until there is no visible contaminant on the conveyor belt surface.
Cleaning the back of the conveyor belt: Then wash and wring the towel, pass the towel from the bottom of the machine through the bottom of the conveyor belt, and straighten the towel. Draw the towel to the front of the conveyor, grab the two ends of the towel, and start the machine to run the machine for several weeks. Since the bottom of the conveyor belt is the dirtiest place, multiple wipes are required. After each operation for several weeks, the towel should be washed out and the above steps repeated.
How to judge the cleaning effect: After the above two cleaning steps, the needle conveyor conveyor belt adjusts the sensitivity to 8 or the highest sensitivity, and starts the machine to make the machine run. If the machine runs smoothly and the probe metal position indicator light does not light, At this time, the clothes without any metal impurities can be smoothly passed through the needle detector channel, that is, the conveyor belt is cleaned successfully!
