11.0.3 Explanation of probable causes and how to remedy them 1. Checking the battery and charger 1.1 Checking the battery An old battery may be run down or the battery charger may be broken. Systems with low power consumption discharge a battery completely to a point where it only yields 8 or 9 V. If no power is being drawn from the battery, 12 V is always shown. This is because the voltage only falls when power is being drawn from the battery. Therefore, when checking the battery’s voltage, the indicator must first receive power for several seconds or even minutes. If the voltage then drops slowly, you can conclude that the battery is run down. The simplest way to test the battery is to replace the battery module. Always check the battery charger. The charger must have an output voltage between 12.5 and 14 V. 1.2 Changing the battery Batteries run down over time. When the battery gets old or has been used a lot, it is best to replace it in order to avoid problems.
2. Control mechanism 2.1 Check whether the scale’s mechanics are jammed mechanically Weigh yourself by standing on the four corners of the forks. Your weight must be identical on all four corners. The indication may vary by up to 1 kg. If so, then all load sensors are working normally and the mechanics are working well with light weights. After this test the scale should be loaded with a normal or heavy load. Use the tare button and reset the display. Leave the weight on the scale and then stand on or beside the load. Each corner must show the same indication with a deviation of plus or minus 1 to 2 kg. If the readings are not identical or the deviation is greater than 1 or 2 kg or if it is unstable, continue to section 2.2.
