Digital Force Gauge Calibration and Maintenance
After purchasing the digital force gauge, most users know more about how to use it, which means that there is no problem with the operation of the digital force gauge. However, once the inaccuracy or failure of the digital force gauge appears, users are often at a loss.
In fact, when the digital force gauge is not accurate, the accuracy can be corrected by changing the parameters inside. The specific method is as follows:
I. Measuring tool preparation
Take 2kg qualified weights and force gauge to be calibrated.
II. Hanging weight
1. Turn on the force gauge, reset it to zero, take the rope to tie the weight of the calibration OK, and measure the total weight of the weight and the rope on the scale of the calibration OK.
2. After the weight is hung on the force gauge, the difference between the data displayed on the screen and the total weight of the weight and the rope is the error value, and the error average of three consecutive operations is the correction error.
3. The calibration cycle of the force gauge is once every six months.
After the force gauge has been calibrated, how to maintain it?
I. Generally, the force gauge need to be warmed up before use. Digital force gauge (such as electronic force gauge, digital force gauge, etc.) usually need to be warmed up for 10 minutes. The hydraulic force gauge is warmed up for about 20 minutes in summer, and longer in winter, at least 30 minutes or more.
II. After preheating, don’t do the test immediately. Electronic force gauge should perform a basic test run, such as rising and descent running; hydraulic force gauge needs a rise and fall test run with hand control box, and if with hydraulic tightening, a test is required to see if the clamp is normal.
III. After everything is normal, the experiment is to be done. What needs to be noted here is not to start the experiment too fast. The main reason is to protect the clamp.
IV. After using the force gauge, all that needs to be done is to turn off the power. On one hand, it is to prevent the force gauge from running automatically, and on the other hand, it is to extend the life of electrical equipment.
V. The last point is that the power transmission part of the force gauge should be lubricated regularly, not too frequently, just once a year.
