(gram).
   (Note: for same specification size of workpiece, same R and sp, measure directly.)
(9) 、Press “QUIT” after the operation and turn off power supply.
 If you want to change parameter in the operation course, press “QUIT” and back to (1)
  (10)  、Printing Function: If you need to print, press “HALT” +“ 。 。” under measuring status
       when the machine equipped with external printer.
IV. Calibration
             Measuring precision might be reduced because of bump in transportation or
      long-term application, so we have to reset for adjusting the machine to enhance the
      precision. Calibration instruction as follows: (Note: Do not set by voluntariness)

Notice: Before the calibration operation, remember to change adjusting mode into
             weight-increasing status under measuring status, otherwise balanced angle will

    Thereinto “X” is “0” or “2”。
         AC = 0 signs non-compensation status(status after calibration)
      AC = 2 signs clamp compensation status(clamp working status after compensation)
Change its value into 0 and then press “EXE”.

X. Common Questions about The System


   1、    Start the motor after showing “Please start the motor.”. After entering measuring

         interface, only the rotate speed vibrates; other numbers no twinkling; red light

         becomes bright. This is caused by difference between real balancing rotate and

         required SP values. Only need to press “SET” key during measuring status.

   2、    The key of “SET” and calibration operation are two different things. Do not confuse
         between them. Do not free to use SET operation. Conduct this operation under our
         debugging personnel‟s guidance if necessary.

   3、    After startup, it displays “Manke Balancing Machine”. It‟s a main interface under
         self-detection status. When it shows this interface, it shows the electrometric box is
         normal. No realistic meaning for measure.

   4、    Start the motor when it shows “Please start the motor.” It enters measuring

         interface, without number appearance, PLL not bright. This is caused by

         photoelectric head inaccurate location. It only needs to set the photoelectric head

         into vertical place or set it in a certain angle and keep it in a certain distance from

         Reflective sheeting. Meanwhile, enter to measuring interface when the PLL is

         bright. If it displays rotate speed but other numbers not twinkling, see the solution 1

   5、    Please    notice,    whether     the    balancing     operation     correspond       with
         “increase/de-weight” (Set “increase weight light” bright when increasing balance
         and set “de-weight light” bright during reducing balance)

   6、    When speed-testing components close to switch and after a period of application,

         clean switch surface in time or adjust sensing distance to ensure its sensibility.

   7、    Stick Reflective sheeting on the workpiece. Common boundary between reflective

         and non-reflective is 0, angle increase in anticlockwise direction (view from right

         side.)
