 SELECTABLE CALIBRATION FEATURE

Calibration is a very important to the accuracy of any balance.  Just as a musician must have one true tone to tune his instrument, a balance needs a true weight to tune itself.  Calibration is done by giving a base point (ZERO) and establishing what is the full capacity (SPAN) weight.  Since SPAN is normally the balance's maximum capacity, the balance now has two precise extreme points: zero and full scale.  The balance can now accurately calculate all amounts in between the base point (ZERO) and full capacity (SPAN.)

A&D balances offer a selectable calibration feature for those people wishing not to calibrate the balance at the full designed weighing capacity.  Calibrating a balance closer to the user's actual maximum weighing capacity will offer a more accurate calibration.  For example, an individual may purchase the A&D EK-6000i which offers the ability to weigh up to 6000g with 0.1g readability.  Instead the user only plans on weighing up to 4800 grams.  The EK-6000i offers the ability to calibrate the scale at 4 programmed capacities - 3000g, 4000g, 5000g or 6000g.  Therefore, to improve even greater accurate the user would calibrate the EK-6000i with a 5000 gram calibration mass.

Balances are influenced by changes in seasonal temperature, humidity, barometric pressure and the gravitational acceleration (the position of your location related to magnetic north) for the location at which the precision weighing instrument is being used.  It is necessary to calibrate the balance when it is being installed for the first time and after any changes of locations.  It is also recommended that a balance be calibrated regularly in order to obtain the most precision.  Most GLP/GMP and Quality Assurance Directives for a ISO manufacturing environment require in their procedure a daily calibration.  Also, in critical weighing applications such as formulation of inks, paints and adhesive a daily calibration is a must.

Precision Weighing Balances highly recommends you consider purchasing the calibration mass at the same time you place your order for your balance.  It will only be a matter of time before you are calling for the calibration mass to be delivered "yesterday".  The calibration mass will also enable you to perform all calibrations within your organization and eliminate in most situations the additional expense of calling a calibration service company in.

A&D designed the GF, GR, HR, GX, HF, HFG, HP, EKi - Series with the user in mind making full digital calibration a cinch.  You can also change the calibration mass value for calibrating your A&D balance to several programmed mass values to meet your weighing needs.  To enter the calibration mass value use the following steps:

  1. Press and hold the "RE-ZERO" key to enter the calibration mode.
  2. Release the "RE-ZERO" key when the balance displays either "CAL or CAL 0".
  3. Press the "MODE" key to change the calibration mass value
  4. Enter the calibration mass value using the following keys: "MODE" key is used to move digit to enter a number; "RE-ZERO" key is used to change a number.  Verify that there is nothing on the weighing pan.
  5. Press the "RE-ZERO" key.  The balance measures the zero-point.

The weight value can deviate above or below the nominal value by the tolerance defined.  To determine the tolerance of a mass, look at the denomination or nominal value of the weight and the appropriate class you need.

All calibration weights are not returnable.  Once your order has been placed it CAN NOT be cancelled.  Please carefully consider this prior to placing your order.  The reason for this is these weights are custom manufactured and are certified on the date they were made.  In addition, if you touch the calibration weight with your fingers the oil in your skin would change the tolerance and we can not take this chance if the weight was returned.

50 LB Cast Iron Test Weight

Quality Guaranteed by the Toughest Standards of All… Our Own.

Designed for scale calibration, our solid cast iron test weights are sealed to ASTM classes 6 and 7 specifications; Class F tolerances are listed in the National Institute of Standards and Technology Handbook 105-1.  All weights are traceable to NIST.  To verify adherence to class F tolerances, OPTIONAL traceable certificates are available for an additonal $75.00. 

Our cast iron weights undergo a special phosphatizing process in which the metal is thoroughly cleaned and mildly etched to allow exceptional finish adhesion.  The weights are then coated with a layer of chip-resistant paint which conforms to NIST Handbook 105-1 standards.  This two-step process ensures a long-lasting finish that greatly reduces the possibility of corrosion.
