The FX120iN digital balance is popular for weighing precious metals (gold, platinum, palladium, rhodium) in the jewelry and pawnshop industry when the metal is bought or sold by weight.
When MN Department of Commerce Weights & Measures Division comes knocking on your door telling you need a legal for trade scale that meets the guidelines in Table 8 of section 2.20 Scales in NIST Handbook 44, 2.2 Theory of Tolerances in Appendix A the FX120iN meets those requirements.
Precious metal dealers must also comply with the requirements of MN Statute Chapter 325F. CONSUMER PROTECTION; PRODUCTS AND SALES and again FX120iN meets those requirements
Additional uses for the A&D Weighing FX-120iN would be for pharmacies requiring a Class "A" prescription scale to maintain their pharmacy license when the requirements are a weighing device with a minimum tolerance of 0.1 grains or 6 milligrams.
The FX120iN NTEP approved (National Type Evaluation Program) complies with the applicable technical requirements of "NIST Handbook 44: Specifications, Tolerances and Other Technical Requirements for Weighing and Measuring Devices".
The "d" (value of scale division) is 0.001 grams and the "e" (value of verification scale division) is 0.01 grams. When "d" and "e" are not the same value the last division on the scale's display is "boxed". If you placed a gold ring on the FX120iN the display might read 7.03 grams. So the item weighs 7.031 grams and since "d" and "e" are not equal the last decimal is uncertain. A pawnbroker could tell the customer - you have 7.03 grams.
A&D FX-120iN is a Class II weighing devices. Handbook 44 defines a Class II balance as any weighing device with 10,000 - 100,000 verified divisions. Since the FX-120iN weighs up to 122 grams and "e" is equal to 0.01 grams it is therefore 12,200 verified divisions. All this information can be verified by downloading the CofC # 08-045A2
Weights & Measures Inspectors uses the guidelines in Table 8 of section 2.20 Scales in NIST Handbook 44, 2.2 Theory of Tolerances in Appendix A for determine to applicable scale for the weighing application such as weighing gold. You can download sections of NIST Handbook 44 - 2012 Edition here.
Table 8 says that the smallest item weighed on a class II scale with a verification scale division size of 0.1 g should weigh at least 5 grams (50 divisions) - the FX120iN meets this description. The smallest item weighed on a class II scale with a verification scale division size of 0.01 g should weigh at least 0.2 grams (20 divisions) - the FX120iN meets this description.
The Theory of Tolerances states that the tolerance allowed on a commercial weighing device should not cause economic injury to either the buyer or the seller. A class II scale with a verification scale division size 0.1 gram is allowed 1 division (0.1 g) maintenance tolerance for weights between 0 and 500 grams. So if you had a known weight and we'll say a 100g calibration weight weighed on a LFT scale with a verification scale division of 0.1 gram the scale could read 99.9g, 100.0g or 100.1g and be within tolerance. At the current market prices for gold ($1228.70 per troy ounce on 3/1/2016), that tolerance would allow a monetary error in excess of $3.95 on every transaction. Since one  troy ounce = 31.1034768 grams therefore $1228.70 / 31.1034768 = $39.503 per gram and if one used a scale verified division of 0.1 gram you need to divide $39.503 by 10 to equal $3.9503 for each tenth of a gram division. Since the FX-120iN is verified to 0.01g the monetary error now drops to 39 cents.
For this reason, the Minnesota Weights & Measures Division requires that scales used for precious metal transactions have an "e" less than or equal to 0.01 g and the A&D Weighing FX-120iN meets the requirements.
You should always check with your local state or county Weights & Measures office to determine their exact requirements for a scale. Many states like Minnesota have very strict penalties for any person buying or selling precious metals by weight and using the wrong scale could result in a criminal penalty if found guilty of imprisonment for not more than three years or to payment of a fine of not more than $40,000, or both.
One of the reason there are not a lot of digital scales that are legal for trade is because the electronic balance has to really measure correctly. The scale needs to incorporate a high quality precision weigh sensor and electronics. During evaluation process a load of one-half capacity is placed on the digital scale more than 100,000 times testing for accuracy and functionality. There are also device markings and design requirements to prevent the scale from being calibrated once placed in service. This is achieved by sealing the FX-120iN by threading a wire security seal through two screws on the RS-232 serial interface plate and scale housing. This prevents access to the calibration switch inside the device.
When the FX-120iN digital balance is first installed it should be calibrated to ensure accurate weighing results. We offer a full line of calibration weights including the recommended OPTIONAL 100 gram calibration weight for the FX-120iN.
Every location in the world is positioned differently to "magnetic north" and therefore the acceleration of gravity is slightly different. Some Weights & Measures Inspectors will calibrate your FX-120iN when they come and inspect the balance and put it into service. Other states required only a licensed certified scale technician to perform calibration and they charge up to $225 just to place the calibration weight on the weighing platform.
Some states will allow you to calibrate your own balance. If you are allowed to calibrate your own balance make sure you watch our youtube video how we walk you through the calibration process. Instead of buying the 100g ASTM Class 1 with NVLAP Certificate you can probably save money buy purchasing the 100g ASTM Class 2 (± 0.50 mg) with NO Certificate for less money in the "Related" section in the top right side of this webpage. Again you should check with your Weights & Measures Division about calibration especially since calibration weights are not returnable.
We understand purchasing a legal for trade balance is a major capital expense and if you have any questions give us a call and one of our weighing experts can discuss your weighing application and get you the most affordable balance for your weighing needs.
There is a lot of confusion when it comes to buying the FX-i NTEP digital balances and hopefully the video above will clear those issues up do you don't purchase the wrong balance.
In the video above I use the FX-300iN and what is covered is applicable to all the FX-iN models which includes the FX120iN. FX200iN, FX300iN, FX1200iN, FX2000iN and FX3000iN. If you read carefully you noticed all the model numbers ended with the letter "N" which designate NTEP Approved or Legal for Trade.
Many people really don't see any difference between the FX-120iN and the FX-120i, but there is. If you require a legal for trade weighing device especially for commercial weighing and you ordered the non-NTEP version (aka FX-120i) you will have problems. As you can guess the FX-iN NTEP Approved models costs more than the FX-i Non-NTEP models.
If you are a pharmacy needing to meet the requirements for maintaining your pharmacy license you want to order the FX-120iN and not the FX-120i. The same goes for a Oregon marijuana dispensary you need the FX-120iN, while Colorado marijuana dispensaries as of March 2016 are allowed to use the FX1200iN, FX2000iN or FX3000iN. Eventually we think Colorado recreational cannabis dispensaries will follow Oregon's rules for marijuana scales requiring the FX120iN since this model has a verification scale division of "e"=0.01g and "d"=0.001g.
So here are the differences FX-i Series and FX-iN Series. When you buy the FX-iN models you receive the manual with a 1 page addendum explaining how to calibrate the balance along with a "sealing plate" and two(2) "sealing screws" and labeling above the display. The FX-120i DOES NOT come with the "sealing plate" and two(2) "sealing screws" and labeling.
You will notice the sealing screw has a hole and this allows the Weights and Measures Inspector to place a wire through the hole and then crimp the wires together with a lead slug similar to how an electric or water meter was sealed to prevent people from tampering. Placing the wire through these screws prevents you from accessing the calibration switch to initialize the start of a new calibration.
Every balance should be calibrated prior to weighing and you should check with Weights and Measures if you can perform the calibration by purchasing your own optional calibration weight, if you have to hire a local licensed scale technician to perform the calibration or if the Weights and Measures Inspector will calibrate the scale when they inspect it and put the scale into service. You'll need to research this on your own and in some states it can cost you over $150 just for the inspection. Typically they will also place a State W&M Seal on the balance with an expiration date since scales typically they have to be verified and inspected for accuracy yearly.
You will see on the front of the balance above the display a label denoting the model number. This is where so much confusion occurs. The model is shown as FX-120i, then a circle with II inside of the circle meaning this is a Class 2 weighing device, CC 08-045 and the wording "The counting feature is not legal for trade". But wait I thought I ordered the FX-120iN yet the balance is labeled FX-120i.
What has happened is AND Weighing converts the FX-120i into the FX-120iN by changing the balance's internal software so it complies with NTEP requirements. Part of this is so the calibration can be locked out also so the last decimal place on the display is "boxed". They also place the sticker above the display identifying the CofC number and supply the two sealing screws & sealing plate. All these changes and A&D markets the product as the FX-120iN and charges more money.
Many marijuana dispensaries either already have a FX-iN balance and want to expand and order another balance or they visited a dispensary so they can figure out the equipment they need to start a store are often confued. Although looking at the digital balance's label is marked either FX-300i for Oregon or for dispensaries in Colorado FX-3000i you need to make sure you order the FX-300iN or FX-3000iN.
