Additional Features

All ACB Plus Scales come with a protective shipping pin that protects the load cell from shock during transit.  Remove the shipping protection pin from the bottom of the scale.  Retain this part so that if the scale is ever transported it can be inserted to protect the load cell from both horizontal and vertical shock during transit.  This is a great feature that substantially lessen the chance of the scale being damaged with rough handling by any freight carrier where our motto is - "fragile means football".  Whether you ship UPS, FedEx or the Post Service seldom does the word"fragile" mean anything. secure load cell with shipping pin

digital electronic scale
The new ACBplus has a lot of new features such as a large and very stable ABS plastic case in a modern attractive design, capacity tracker and a low battery indicator.  The tactile feedback keypad is clearly marked, color coded for easy operation.  A spirit bubble indicator is located in the left hand corner to assist in leveling the scale and the 4 adjustable feet makes this a cinch.  The capacity tracker (also known as a fill guide) is positioned below the number displayed and allows you to always keep track of the available weighing range right up to the limit.
battery powered scale     rs-232 data communication port
All ACBplus Series come standard with an 110V AC adapter to operator off a wall power receptacle.  The ACBplus scales also have an internal rechargeable battery making them totally portable.  The typical battery life is approximately 70 hours depending on the usage of the backlight.   RS-232 interface comes as standard for printing of results using the optional Adam thermal printer or connection to a PC using an aftermarket data collection program enabling the balances to be integrated into an ISO/GLP quality system.
electonic scale  
The new ACBplus is designed with 4 adjustable feet letting you level the scale quick & easy.  The scale housing is constructed of ABS plastic and features a security bracket at the rear of the scale for lock down applications for classroom applications.   All ACBplus models come standard with a plastic draft shield for precision weighing.  The top of the draft shield can be lifted off for easy access to the weighing platform.  This draft shield provides peak performance by limiting air current movements.

3 Selectable backlight modes

  1. Auto backlight mode - When the weight is over 10 scale divisions or any of the keys are pressed, the backlight will be turned ON.  When the display shows zero for about 8 seconds, the backlight will go OFF automatically.
  2. Backlight will always be ON
  3. Backlight feature disabled and will always be turned OFF.

calibration massesTo ensure consistent accuracy and tip-top performance the ACBplus can be easily calibrated using the auto calibration function through the keypad.  Auto Calibration requires that you have the calibration mass.  These masses are optional accessories and we ALWAYS recommend that you purchase the calibration mass so that you never need a scale company to service your scale and charge you some outrageous price.  Most scales on the market today including the ACBplus Series incorporate custom designed integrated circuits resulting in really nothing a local scale company can do to service a scale.  Basically, all they can do is come out with a bottle of Windex or Fantastik and clean the exterior body of the scale and calibrate the scale. 

gram scaleIf there are ever any other problems with the scale other than calibration then it really can only be serviced by the manufacturer, Adam Equipment in Danbury, CT, since the motherboard consist of VLSI(very large scale integrated circuits) and we know of very few scale service companies with a digital logic analyzer, or the proper tools to remove and replace surface mount fine pitch components.  Typically the time to resolve a board problem is best solved by just replacing the whole board and we feel the manufacturer is best to make this decision.  All Adam Equipment products are backed with a 12 month manufacturer's warranty for parts and labor under normal use.

The ACB offers a unique feature enabling you to customize the calibration weight anywhere over the scale's weighing range.  Most balances offer only the choice of one calibration weight while other models might let the operator choose one of 3 pre-selected values.  The ACB gives you the freedom to select any value to calibrate the scale, although we always recommend calibration a scale at 2/3 to full capacity.  By accessing the function menu you can custom configure the set-up parameters.


Additional customized set-up parameters include:digital scales

  • Initial weigh unit the ACB powers up.  This is a convenient feature and lets you power up the scale in carats if you're a jeweler, pennyweight if you're a scrap precious metal dealer, grains if you're a marksman for making ammunition.  If you don't want to use this feature you can still use the "UNIT" button and scroll through 1 of 13 weigh modes.
  • Disable weigh units.  If you are using the ACB in a production environment and want to make sure your workers are never weighing in any other modes than pounds you have the ability to disable all other weigh modes via the function menu.  Using this feature removes that weighing mode from the choices available when one presses the "UNIT" key.
  • Auto Zero recovery range. Choose the auto zero recovery range from 0 to 3 scale divisions. The auto-zeroing feature is internal software that compensates for drift from the loadcell.  Problems can occur when light items/powder (2 or 3 scale divisions) are added to the platform and the internal software thinks the change on the loadcell is due to draft when it is actually the added weight on the platform.  With scales like the Ohaus Scout and Acculab VI-Series which don't allow the operator to disable the auto zeroing feature it is possible literally to add a powder in 3 division interval over hundreds of times and the display will still show 0.0.
