Use the first edge of the heart medical design to add power to the continent. The power source is not transmitted to the continent and the machine is drawn! Network value, and then under the 10o gram low voltage sample of 501 or 60x, on the "degree", make the sexy limit quantity on the workbench contact with each other, and then give the sensor the same value of one-tenth of the indication range of the figure as the time on the indicator report || tt || in the "stand", make the sensor and the workbench quantity on the life of the volume adjustment adjustment from the system to the ratio end, reverse out of the back station move range pressure in the "stand", the element in the small guard benefit value block this pair of military engraving finally move each gear in turn to the zero position of the programming switch now share each quiet when the zero position of the volume can be adjusted to the corresponding scale on the workbench instrument; pay attention to the case scale! Use the lifting mechanism to gently lift the probe, and then let it fall freely. The lifting amount should be greater than the indication range of the ten gears, and the lifting amount should be consistent. Repeat 1C times, take the maximum and minimum indications of each time, and make them consistent with the normal determination on the platform. Record the scale line on the two pointers. When the measuring head is on the measuring head, align the left and right four probes with the three probes, and use the force equivalent to 2C of the material design force to make the sensor fall! The amount on the workpiece is relative, and the sensor is slowly moved to a certain extent. After the measurement is accurate, lift the probe gently again. The lifting amount should be greater than the indication range of the ten gears, and then gently put it down again. Find the value of the pointer after the rise, collect the average value, and align it with the indicator.The wave line is again plated with symptoms. The set of measurements of the instrument stand workbench is determined according to the corresponding method. The measurement of the index of the batch is the same as the first batch of the file. The zero scale is negative, and the full dose tablet line is then divided into four equal parts (or six equal parts) according to the low range of the display. The corresponding amount is changed in total, and the values ​​of these sensory types are checked in turn on the file. The three straight lines of the film are the smallest points. The two god faces of the special forget the well stand are connected to each other! Let the adjacent degree line of the Shangyu line overlap, and the film can be determined at the time of starting: the most change of the straight salt || tt| |In, after completing a gear, the range will be expanded and the minimum division value will be adjusted. The device will also adjust the loss needle separately. During the time, take the change in the value of the loss lamp that is lit within the reverse time. At the valley end, when the memory position is half of the small division value or half of the gear... or one of the whole, the meter will be placed under the measurement ratio and protection ~ original, and the specified time will be indicated by the large value of the north

Test monitoring
In ""When theft, the quality process is the minimum, the actual trust is in the position, turn the adjustment code, so that the indicator light is evenly rotated, so that the indicator light is lit in the special danger plan, the total water is correct, and the sequence is heavy! Take 15 times the change of the signal light's indication value according to the previous month
In a gear, make the sensor and the case Work to accept orders, half make the pointer overlap with the full distance money, : education crying input -L5DH, 22V special power in the rhyme light straight + 10% of the energy change, read the maximum change of the wine run: the sensor installed on the platform to measure the vertical self-mouth, and then use the dynamometer to move the sensor along the tail of the station tide. Inspection rules 7.1 Factory inspection |The probe is slowly increased in force, and the pointer passes the test number on the dynamometer when it is raised. Then the probe is slowly moved downward, and the pointer passes the test number on the dynamometer. The dynamometer must pass the quality inspection of the manufacturer before it can leave the factory. The factory inspection items should include the contents of 5.1 to 5.14. Inspection quantity 100
