Electronic loadometer debugging method
1, electronic loadometer bearing key debugging, the weight equivalent to the maximum weight is evenly added to the electronic loadometer bearing platform, according to the various weighing display instructions in the position and method, so that the display value and weight value is consistent, remove the weight, and confirm that the empty balance is displayed as "0". Finally, the maximum weight is divided into several parts, which must include the minimum weight of the scale, the maximum weight and tolerance change of each weighing point, requires that the weight error of each point of the electronic weighometer is not greater than the maximum tolerance requirements of each measuring point.
2. Use the digital voltmeter to measure the output voltage of each weighing sensor of the electronic weighometer in turn. If there is any inconsistency, the corresponding two precision adjustable resistors in the junction box can be adjusted to reduce the difference between them. However, the adjustment must be noted that the rotation direction of the two adjustable resistors should be the same, and the rotation amount should also be the same. When rotating clockwise, the resistance will decrease, the output voltage will increase, and the display value will increase; otherwise, the other way around. Until adjusted to the electronic loadometer only weighing sensor output consistent. Debugging generally available weight method, the biggest weighing weight, 1/10 in turn put to electronic scale load bearing center position and the weighing sensor at the top of the bearing platform, only with real difference method to measure accurately the only differences of the weighing sensor output quantity, at the same time adjust each ChengChongDian electronic loadometer weighing sensor respectively corresponding two precision adjustable resistance, decrease the difference between each other, but the direction of rotation and rotation as well.
