6.12 The temperature difference of the three supporting points is measured with a cloud ruler until the main vertical distance of the three supporting points of the ruler is measured to the main point. The maximum and minimum differences are as shown in the manufacturer's specification.
6.1.3 Also as shown in the variable or
Egg Figure 2, install this straightness detection ruler on the calibration device of the general straightness detection ruler (hereinafter referred to as the calibration device 1), and measure the micrometer head of the calibration device to the zero position: then read the pointer of the indicator table of the verticality detection ruler to the zero position. Rotate the micrometer head forward (backward) to make the indicator table deviate from the zero position, and move the micrometer head to make the micrometer head refocus on zero and read the pointer on the indicator table. 6.1.4 Small error
Install the calibrated calibrated scale on the calibration device, turn the calibration device’s micrometer head, adjust the pointer to the zero position, and set the micrometer reading to zero.
Use 5 accurate points, 3, 9, 12, 15: Before turning the micrometer head of the calibration device, the calibration step should be to check the zero position of the scale indication: it should be turned micrometer, if the scale is zeroed, it should be more wrong:
Calibration, turn the micrometer head in turn, and get the standard value relative to the calibration point: the reading of the calibrated scale is equal to the standard value, and the reading minus the standard value is the actual indication error.
6.2 External inspection
6.2.1 The vertical load of the working mountain
. Release the epidemic type! :
5-positive stimulation,
4 sensitive control scale" steam surface
Put the external inspection scale on the working mountain and put it on the flat plate L, the pressure is 1nm, the test frame length and the working mountain are multiplied by 1nm, and the linear measurement reaches the index of 21. .2.3 The vertical measurement of the two working mountains
The calipers are used to measure the distance between the work seat and the work seat respectively: measure to one point, and the difference between the minimum values of the calipers is the vertical measurement of the working mountain.
6.2.3 Zero value error
Put the calibrated inside and outside right angle detection ruler and the inside and outside right angle measurement ruler calibration device (hereinafter referred to as calibration device) on the flat surface as shown in Figure 3, ensure that the calibrated ruler fits tightly with the flat surface and the calibration device Ⅱ, and then observe the indicator of the calibrated ruler. At this time, the indicator indicates the zero value error of the outside angle: then put the calibrated ruler as shown in Figure 4, ensure that the calibrated ruler and the calibration device Ⅱ fit tightly, and at this time, the indicator indicates the zero value error of the inside angle. Take the maximum value as the zero error of the calibrated inside and outside right angle detection ruler,
6.2.4 Indication error
If the ruler is as shown in Figure 3, the calibration needs to be supplemented with the indication error of the scale: the ruler is as shown in Figure 4. Note the error of the calibration value on the right side: When calibrating, adjust the measuring head of the calibration device to zero, select 0, 11, 3, 5mm, 7mm as 3

calibration points. Rotate the micrometer head according to the model, give the standard value relative to the calibration point, read the digital value from the indicator of the calibrated ruler, the reading minus the standard value is the indication error of the corresponding point, so 3

[deck: 2-precision ruler:
light measurement-probe
Use steel ruler to directly measure the length of each scale of the measuring ruler: the measurement interval is 20mm. The reading of the steel ruler minus the nominal value of the ruler is the ruler length deviation. 6.4 Thickness deviation of the flat ruler
Take the upper ruler as the standard, and measure at intervals of 3mm. When measuring, place the height caliper and the feeler gauge on the flat plate, adjust the height caliper up and down, and put its claws to touch the corresponding scale line of the flat ruler. Read the highest value from the height caliper. The reading value minus the nominal value is the thickness deviation of the flat ruler. 6.5 Relative deviation of the length and width of the white grid Use a steel ruler to measure the length and width of the white grid respectively, subtract the nominal value from the reading value, and then divide it by the nominal value to get the relative deviation of the length and width of the white grid. 6.6 Slope ruler
6.1 Zero value error of level
Put the slope ruler flat on a flat plate, adjust the adjusting screw to make the - end of the water bubble align with the middle scale line on one side; then rotate the slope ruler horizontally 180°: put it in the same position, and check whether the position of the level bubble on the side deviates from the middle scale line. Half of the deviation is the zero value error of the level. 6.6.2 Error correction
Use the block as the standard, and calibrate it by 5mm
First Level the flat plate so that the angle between the plate and the water surface is less than 0.mmm. Then place the slope gauge on flat plate 1 and use the adjusting screw to adjust the bubble of the spirit level to the middle position. The pointer of the slope gauge indicator should point to zero. After adjustment, place a 5-diameter plate under the front plane and use the adjusting screw to adjust the bubble of the spirit level of the slope gauge to the middle position. Note the reading of the indicator. The reading minus the standard value is the indication error of the slope gauge at that point. Replace other gauge blocks in turn and measure the indication difference at other points.
