Adjusting the sensitivity of the precision balance

Procedure for adjusting the sensitivity of a precision balance 1) The balance should be leveled and the program switch of the balance should be turned on.

2) Turn on the balance and make the balance display a stable zero.

3) Hold down the TARE key and hold it. The balance shows “BUSYCAL and value (correction weight value)”.

4) Place an adjustment weight equal to the value displayed at the third point on the balance pan. This calibration weight should be less than 2% error, if there is over tolerance there will be "positive sign" or "negative sign" displayed on the display. The "positive sign" means that you want to increase the mass value; otherwise "negative sign" to reduce the mass value, the balance shows "BUSYCAL" and the correction weight value.

5) The “g” symbol appears on the balance display with an acoustic signal.

6) Remove the adjustment weight. The balance will show the zero position later.

7) Close the balance and the display shows "STANDBY".

8) Press the "CAL" key with one hand and press the switch key with the other hand. The balance is displayed until "CH4" stops.

9) Press the TARE key again and the balance displays “CH4CAL”.

10) Release the "CAL" key and the balance displays "BUSYGAL" and "0.0000g".

11) The balance shows "0.0000gCAL"

12) Press "CAL" button once and the balance shows "BUSYCALC".

13) "BUSYCALCC" is displayed later.

14) After the balance shows the zero position.

15) If the balance has a newly installed parameter "EEPROM" memory, repeat steps 12 to 14 again.

16) Call up the balance program page 4, and the display will cycle “41A or 42”.

17) When the program code 42 appears on the display, press the balance peel key to make the balance setting program “42▲”.

18) When the last digit of the program code is zero, press the TARE key to return the balance to the zero position of the weighing program.

19) Return the balance program switch to the locked position.

The above is the method for adjusting the sensitivity of a precision electronic balance. It is hoped that it will help you accurately measure the accuracy of objects.

PCB Cutting Machine

This type of SF-706 machine have to keep PCB board,the circular blade is moving.It is suitable for Special height for ultra high component can be 70mm.

This type of SF-701machine through adjust the height of track manually and control At 0.01 mm to solve the problem of V-CUT depth. Accept made to order super high components on the PC board such as power supply.The highest for 400mm is also accepted to customize.

The type of SF-705 v notch PCBA Cutting Machine which is suitable for Thickness of the to-be-cut base plate: 0.5-2.0mm, max. length of 300mm PC plate. Then Processing V-PCD plate, aluminum plate and CUT plate, etc.The using way is Controlled by electric pedal or pneumatic pedal, hoe knife plate splitting is completed by the motion of air cylinder.
