When reading the balance, the travel code should read the scale _ _ _ _ corresponding to the left end of the travel code.

When using the sky level, the object on the left is coded to the right, and when reading, the number on the left of the code is read.

It can be seen from the scale of the balance commonly used in the laboratory that the wandering code has a certain width, but when the wandering code is dialed to the far left of the scale, its left edge refers to the zero scale line. Therefore, after the wandering code is moved, the scale value corresponding to its left end should also be read. So this statement is correct.

The chemical dictionary tells you how to read and use the pallet scale. Pallet balance is a common measuring tool in our daily life. It can be seen in vegetable markets, consignment points and many other places, which is closely related to our lives. Let's see how this pallet balance reads.

Reading method of traveling code of pallet scale

1, released. Put the balance on a horizontal surface, and be careful not to put it on an inclined plane.

2. Dial. Before weighing, make sure to set the scale of the balance to the zero scale line.

Step 3 adjust. Adjust the balance nut of the balance so that the pointer of the balance is located at the center line of the dial. At this time, the adjustment method can remember a formula: the pointer is left hand and the nut is right hand; Pointer to the right, nut to the left.

Step 4 measure. When weighing, put the object on the left plate, estimate the mass of the measured object, add the weight to the right plate appropriately with tweezers, and adjust the position of the stray code to balance the balance. Pay attention to the first big and then small when adding weight, and the first small and then big when reducing weight.

Step 5 read. When reading, the mass of the measured object in the left plate is equal to the mass of the weight in the right plate, plus the scale value corresponding to the wandering code on the scale.

6. Accepted. After the measurement, take out the object, clamp it with tweezers, and put the weight back in the weight box. ?

Pallet balance using formula

1. The left object and right code should be zeroed first, the balance must be leveled, the weights should be clamped in order, and then zeroed and put into the box.

2. Screw scale, pointer scale with tray. Adjust the screw to achieve balance, and separate the target code left and right.

3. Use tweezers to get the code, first big and then small. Drugs can't be put directly, so they should be restored after weighing.
