First input the RPM value according to the methods of Section 2-2. After the eight steps have been finished, the (4) switch should be at the "Balancer" condition; on the display board, the "Wait" lamp is off and the "H---" disappears, but a set of input RPM value will show up.
(2). First of all, it is necessary to determine if the specimen is to be corrected the unbalance by the way of plus or minus (see Fig. 3.1). Then turn the (11) to the "+" (plus) or "-" (minus) condition.
(3). Adjust all the dial (7)、(8)、(9) and (10) to the middle, that is, the (7) and (9) are adjusted to "5", and the (8) and (10) are adjusted to "0".
(4). Treadle down the pedal switch to make the specimen rotate; the values of the L and R amounts shown on the display board are the left and right unbalanced amounts of the specimen. Then use the (13) L / R strobo switch to select the strobo indication of the left or right unbalanced angle. Looking from the front of the machine, the mark located on the same horizontal line as the axis of the specimen is the unbalanced angle (see Fig. 3.2 for rotor or Fig. 3.3 for fan blade). If the (11) switch is turned to the "+" position, under the lighting of the strobo, the A point in Fig. 3.1 will be still at the horizontal direction; if the (11) switch is turned to "-" position, the B point will be still at the horizontal direction. An example is given for explanation:
Given that the (11) switch is turned to "+", press the L of the (13) switch and find the mark "5" is still at the horizontal direction; then press the R of the (13) switch and find the mark "2" is motionless at the horizontal direction. This means that the unbalanced angle of the specimen is "5" on the left side and "2" on the right side, which need the plus correction.

An example is given for explanation:ระบุว่ามีเปิดสวิตช์ (11) "+" กด L ของสวิตช์ (13) และค้นหาความหมาย "5" จะอยู่ในทิศทางแนวนอน จากนั้นกด R ของสวิตช์ (13) และค้นหาเครื่องหมาย "2" คือพระกรที่ทิศทางแนวนอน ซึ่งหมายความ ว่า มุมแจกของตัวอย่าง "5" ด้านซ้ายและ "2" ทางด้านขวา ที่ต้องการแก้ไขบวก
