  • Page 5: Basic Operation

    1. INTRODUCTION This manual describes how the MC Series Mass Comparator Balances, MC-1000 and MC-6100, work, and how to get the most out of them in terms of performance. Read this manual thoroughly before using the balance and keep it at hand for future reference.

  • Page 6: Unpacking The Balance

    2. UNPACKING THE BALANCE The balance is a precision instrument. Unpack the balance carefully. Keep the packing material to be used for transporting the balance in the future. The packing contents depend on the balance model. See the illustrations to confirm that everything is contained..

Place the breeze break on the main unit receptors, and dust guard from your balance. To remove the dust guard, remove the two Breeze break screws that secure it to the balance.
  • Page 8 Auto-centering pan (AX-MC1000PAN) installation procedure Caution: During installation, do not apply excessive force to the balance. When used as a mass comparator, the balance can achieve even more precise weighing, by using the auto-centering pan (sold separately), which reduces eccentric loading errors. 1.

  • Page 12: Installing The Balance

    To get the optimum performance from the balance and acquire accurate weighing data, note the following: 3-1 Before Use The MC series is a high-precision balance with a resolution of 1/10000000. It is prone to changes in temperature and pressure, static electricity, drafts and vibration of the installation site.

  • Page 13: During Use

    Warm up the balance for at least 30 minutes. Plug in the AC adapter as usual. Calibrate the balance periodically for accurate weighing. Before using the balance for the first time or after having moved it to another location, warm up the balance for six hours or more to allow the balance to reach equilibrium with the room temperature, and then calibrate the balance.

  • Page 14: After Use

    3-3 After Use Avoid mechanical shock to the balance. Do not disassemble the balance. Contact the local A&D dealer if the balance needs service or repair. Do not use organic solvents to clean the balance. Clean the balance with a lint free cloth that is moistened with warm water and a mild detergent.

  • Page 16: Weighing

    The table below lists the weight class and recommended measuring range for each model of the MC series. The measuring range is determined so that the balance repeatability is to be less than one third of the maximum permissible error for each weight class.
  • Page 17 When building into a system When a special weighing pan is to be designed, the weight of the pan and the material to be weighed should not exceed the weighing capacity of the balance. To reduce influences of static electricity and magnetism, use materials other than resin and magnetic material such as iron.

  • Page 18: Response Adjustment / Self Check Function

    6. RESPONSE ADJUSTMENT / SELF CHECK FUNCTION This function detects the influence on weighing that is caused by drafts and/or vibration at the place where the balance is installed and sets the response characteristic automatically. When this function is selected, the balance self-checks the performance at the same time. Two modes of response adjustment are available: automatic and manual.

  • Page 19: Manual Response Adjustment

    Notes If improper performance is found in the self check, the balance displays CH no . Contact the local A&D dealer for repair. If the automatic response adjustment fails, the CH ng . Check the ambient balance displays conditions such as breeze and vibration, also check the weighing pan.
