Tip 3: How to repair the scale
Not always such an instrument as Libra, especially if they are electronic, can be fixed by themselves. Pay attention to a few recommendations that will help you cope with the failure without contacting a specialist.
Instructions
1
Mechanical Libra-No. First of all, check the spring on which the load hangs. Very often the failure consists in the failure of this part, and then the spring needs to be replaced. The spring can both pereteryatsya, and just jump out of the grooves of the device. In the latter case, unfold the body of the device, insert the spring into place and ready! Bezmen is also electronic. In this case, replace the batteries, and if this does not help, then the device is best taken to the workshop for diagnosis - you could rip it too heavy.
2
Electronic Floor Standing Libra. First check the batteries. It is possible that all repairs will be limited to their replacement. The reason can also be in the loose connection of the loop connecting the weighing board to the display. This fault can be eliminated by yourself. To do this, remove the body of the balance. Take a small wooden bar and insert it between the bottom of the case and the board. Thus, you raise the board slightly and press it more tightly against the display of the balance.
3
Floor electronic scales also havespecial contacts. When weighing, the weight of the body presses against the weighing cover, which is slightly lowered, and the contacts are in tight contact with the special "legs" of the balance. The metal of contacts from frequent use can be thinned, the contacts will stop closing, and Libra will produce an error. Replace the contacts using a suitable size relay, and then solder the standard wires to them. If the breakdown was in this, then after this simple operation Libra will work as new.
