How to adjust the level bubble of a precision balance?


Release time:

2022-07-15

The uneven position of precision scales in the measurement process will produce measurement errors. The higher the measurement accuracy, the greater the error. Most precision scales have the function of calibrating the level. There are level bubbles behind the precision scales. Pingpu must be in the center of Shougang, otherwise the measurement will not be correct. After the adjustment, please try not to move. Otherwise, the floor dimension circle may be offset and needs to be re-aligned.

How to adjust the level bubble of a precision balance?

The uneven position of precision scales in the measurement process will produce measurement errors. The higher the measurement accuracy, the greater the error. Most precision scales have the function of calibrating the level. There are level bubbles behind the precision scales. Pingpu must be in the center of Shougang, otherwise the measurement will not be correct. After the adjustment, please try not to move. Otherwise, the floor dimension circle may be offset and needs to be re-aligned.

Precision balance generally has two flat base, usually in the back, the front also have. Flipping the two flat-foot supports allows the balance to be leveled.

1. Turn over the left or right support frame and align the elevation bubble to the center line of the liquid cavity first.

Flipping the left and right flat-foot support frames separately is actually to adjust the inclination of the balance, and the flat gun can definitely be adjusted to the center line.

The key is which side leveled the support frame. Beginners can judge this. First, manually tilt the electronic scale to make the level foam reach the midline, and then lay the support frame flat. I don't know which one is high or low, adjust the height of a level base, and the level foam can move to the midline.

Note: The next step can only be performed after the center line is reached.

2. Turn over the two flat-foot support frames at the same time, with the same amplitude, clockwise or counterclockwise, so that the level moves from the midline to the center of Shougang.

If the support frame is rotated counterclockwise or counterclockwise at the same time, the inclination of the balance will not change, so that if the flat gun does not deviate from the centerline and there is no problem with the turning direction, it can reach the center of Shougang.

Simultaneous clockwise or counterclockwise flip: Two hands flip the support frame at the same time (one hand in front of the chest, one hand outside the chest, counterclockwise usually clockwise or counterclockwise flip the support frame).

Direction problem: it is not easy for beginners to judge direction. You can manually lift the support frame or other support frames to move the blister to the center, and then observe where the support frame is laid flat to determine whether it needs to be raised or lowered.

The second step is to pay attention to the width of both hands to be consistent. If there is no match, the liquid bead will be offset from the midline. If it is offset, it can be done from the beginning. After proficiency, it usually takes 1-2 minutes to smooth the level foam of the precision balance.

Level bubble category

Glass level bubble:

High-precision glass with long blisters, highly transparent, and a shelf life of 5 years. It can be turned around the accuracy 30 'and 0,0' axes to maintain accuracy.

plastic grade level bubble:

The accuracy of the level dimension circle is also known as the angle value. For a circular floor dimension circle, the accuracy indicates the slope of the floor dimension circle when the dimension circle moves 2mm from the center of the line of differentiation to any radius. For long floor dimension circles, the accuracy indicates the slope of the floor dimension circle when the dimension circle moves 2mm along the horizontal dimension circle axis.

Metal level bubble:

The metal-grade level bubble combines the glass plate with precision R and the metal shell such as aluminum alloy, copper or stainless steel through cold working, which is beautiful and durable, and easy to install. Accuracy can choose 5'2mm-60'2mm, mainly suitable for tripod, level, high sensitivity balance, etc.
