A&D FX-3000i Manual, Explained: Setup, Keys, Modes and Calibration
The FX-3000i manual in plain language: the A&D FX-3000i is a 3200 g x 0.01 g precision balance with a one-second C-SHS reading and an external CAL key, not an internal mass. Here is how to set it up, use the keys and modes, and calibrate it with a 3000 g weight (not included). In stock at MNM Scales for $725.00 (regular $1,655.00).
Short answer: the official A&D FZ-i / FX-i instruction manual (1WMPD4001863E) covers installation, the keys, weighing units, counting, percent and statistical modes, and external calibration for the whole FX-i line, including the A&D FX-3000i. This 3200 g x 0.01 g precision balance uses a Ø150 mm stainless pan, has no internal calibration mass, and is calibrated with a 3000 g external weight (factory setting; the weight is not included). MNM Scales is an authorized A&D dealer and stocks the FX-3000i at $725.00 (regular $1,655.00). Add in-house calibration with a certificate for $195.00, or NIST calibration with a NIST-traceable certificate for $495.00, before it ships.

The A&D FX-3000i is the 3200 g x 0.01 g model in A&D’s FX-i precision-balance line. It uses A&D’s Compact Super Hybrid Sensor (C-SHS), a bright vacuum fluorescent display and a Ø150 mm stainless pan, and it settles in about one second in the FAST setting. This page walks through the setup, keys, modes and external calibration most users need from the official A&D FZ-i / FX-i instruction manual (1WMPD4001863E). It is an FX-i precision balance, not a compact EK-i Everest scale; the compact line is covered in our A&D EK-i series guide. Choosing between a precision balance and an analytical balance?

FX-3000i vs FX-300i, and the rest of the FX-i line
The FX-3000i and the A&D FX-300i share the same FX-i chassis, keys and external-calibration procedure. The difference is capacity and readability. The FX-300i weighs up to 320 g in 0.001 g steps on a Ø130 mm pan, with a 300 g factory calibration weight. The FX-3000i weighs up to 3200 g in 0.01 g steps on a Ø150 mm pan, with a 3000 g factory calibration weight. Choose the FX-300i when you need milligram-level readability on smaller samples; choose the FX-3000i when you need a 3.2 kg capacity and 0.01 g is enough. The same 0.01 g step at 5200 g is the A&D FX-5000i. This page stays on the FX-3000i. For the 120 g and 320 g FX-i models, including the NTEP FX-300iN, see FX-120i vs FX-120iN vs FX-300i and how to calibrate an A&D FX-120i.
| Model | Capacity x readability | Pan | Factory cal weight | Price |

| FX-3000i (this guide) | 3200 g x 0.01 g | Ø150 mm | 3000 g (not included) | $725.00 (reg. $1,655.00) |
| FX-5000i | 5200 g x 0.01 g | Ø150 mm | 5000 g (not included) | $745.00 (reg. $1,780.00) |
| FX-3000iN (NTEP alternative) | 3200 g x 0.01 g, NTEP Class II | Ø150 mm | 3000 g (not included) | $799.00 (reg. $1,675.00) |
If you want the same 3200 g x 0.01 g capacity with internal (one-touch) calibration, see the A&D FZ-3000i at $972.99 (regular $1,825.00), in stock. The difference between internal and external calibration in this family is explained in internal vs external calibration balances: A&D FZ-120i vs FX-120i. This page does not retell that comparison.
How to set up the FX-3000i
The official manual (section 2.2) has you assemble the balance this way:
- Place the balance on a solid weighing table and set the Ø150 mm pan on the pan support.
- Level the balance by turning the leveling feet until the bubble in the spirit level is inside the red circle.
- Connect the included AC adapter to the jack on the rear of the balance, then to the outlet. Confirm the adapter matches the local voltage and receptacle.
- Leave the balance connected, with nothing on the pan, for at least 30 minutes before use or calibration.
A small breeze break is standard on the 120 g, 200 g and 300 g FX-i models, and on the FZ-i models. It is not included with the FX-3000i. After the warm-up, run an external calibration with a 3000 g weight as described below, then press the RE-ZERO key before each weighing and place the sample in the center of the pan.
FX-3000i keys and modes
Section 4 of the official manual describes the keys. A short press is the normal action during weighing. A press-and-hold is about two seconds.
| Key | When pressed | When pressed and held |
|---|---|---|
| ON:OFF | Turns the display on or off. Available at any time; pressing it during an operation interrupts that operation and turns the display off. | Same (on or off) |
| SAMPLE | In weighing mode, turns the minimum weighing value on or off. In counting or percent mode, enters sample-storing mode. | Enters the function table |
| MODE | Switches among the units and modes stored in the function table | Enters response adjustment (FAST, MID or SLOW) |
| CAL | Cancels a setting in progress | Enters external calibration (the display shows Calout). The FZ-i models use a short press of CAL for one-touch internal calibration; the FX-3000i has no internal mass. |
| Outputs the weight on the standard RS-232C port, and confirms a setting | No function at the factory setting | |
| RE-ZERO | Sets the display to zero (zero or tare, as the balance determines) | — |
Press MODE to step through the stored units and modes. Counting mode (pcs) uses Automatic Counting Accuracy Improvement (ACAI). Store a unit mass with 5, 10, 25, 50 or 100 sample pieces, then add more pieces as the display prompts so ACAI can refine the unit mass. A&D recommends a unit mass of at least ten times the readability, which is 0.1 g on the FX-3000i. Percent mode stores a 100% reference mass (minimum 1.00 g on this model). The balance also has comparator, hold (animal weighing) and statistical calculation modes, which are selected from the function table or the stored MODE sequence.
FX-3000i calibration
The FX-3000i is an external-calibration balance. There is no internal mass and no one-touch Calin cycle; that function belongs to the FZ-i models. Calibrate it when you first install it, after you move it, when the room conditions change, and on a regular schedule. Use a solid table, keep drafts and vibration off the pan, and warm the balance up for at least 30 minutes with nothing on the pan.
The official manual (section 8.1) lists these usable external weights for the FX-3000i, FX-3000iWP and FZ-3000i: 3000 g (factory setting, shown in bold in the manual), plus 2000 g, 1000 g and 500 g on software version 3.10 or later. You can trim the entered weight value within −0.50 g to +0.50 g. The calibration weight is not included with the balance. A 3000 g weight is the factory setting and the value the balance will request unless you change it.
Section 8.3 of the official manual is the external-calibration sequence:
- Connect the AC adapter and warm up the balance for at least 30 minutes with nothing on the pan.
- Press and hold the CAL key until the display shows Calout, then release the key. The balance shows Cal 0.
- To keep the stored calibration weight (3000 g at the factory), go to the next step. To choose a different usable weight, press SAMPLE, then use RE-ZERO and MODE to select or trim the value, and press PRINT to store it.
- With nothing on the pan, press PRINT. The balance measures zero. Do not allow vibration or drafts to affect it.
- When the balance displays the calibration weight value, place that weight on the pan and press PRINT. The balance measures the weight.
- When the display shows end, remove the weight. If GLP output is enabled, the balance may show glp and send a calibration report through RS-232C, then return to weighing mode.
- Place the calibration weight back on the pan and confirm the displayed value is within ±2 digits of the specified value (on this model, ±0.02 g). If it is not, check drafts, vibration and the pan, then repeat the procedure.
This is the FX-3000i procedure, including its 3000 g factory weight. The 120 g and 320 g FX-i models use the same key sequence with different weights; those steps are in how to calibrate an A&D FX-120i. For general calibration methods and when to use a service, see how to calibrate a scale.
MNM Scales can also calibrate the FX-3000i for you. Because this balance’s 3200 g capacity falls in the 2.2–6.2 kg tier, in-house calibration with a certificate is $195.00 and NIST calibration with a NIST-traceable certificate is $495.00. Both were in stock when we checked on November 11, 2026. Add either option to your order and our TDA-registered technicians calibrate it in-house before it ships, or send a balance you already own for mail-in calibration, nationwide by mail, in-house and NIST. On-site service in the Houston area is $295 plus $2 per mile round trip; see scale calibration in Houston or get a quote. Call (832) 290-3120 with questions.
Is the FX-3000i NTEP?
The FX-3000i is non-NTEP. The current National Type Evaluation Program certificate for this family, NCWM Certificate of Conformance 08-045A6 (Active, issued August 23, 2024), covers the NTEP FX-i models, including the FX-3000iN, as a Class II non-computing scale at 3200 g with a 0.01 g display division (d) and a 0.1 g verification interval (e). The certificate table does not list the unsuffixed FX-3000i. Here is an NTEP alternative: the A&D FX-3000iN, 3200 g x 0.01 g, NTEP Class II, $799.00 (regular $1,675.00), in stock. Read what NTEP and legal for trade mean, or check a model with our legal-for-trade scale checker.

Frequently asked questions
Where can I get the FX-3000i manual?
A printed A&D FZ-i / FX-i instruction manual (1WMPD4001863E) ships in the box with the FX-3000i. This guide walks through the setup, keys, modes and external-calibration steps most users need from that manual. The same manual also covers the other FX-i and FZ-i models.
How do I calibrate the A&D FX-3000i?
Warm the balance up for at least 30 minutes with nothing on the pan, then press and hold CAL until Calout appears. At Cal 0, press PRINT with the pan empty, place a 3000 g calibration weight (the factory setting; not included) on the pan when the display asks for it, and press PRINT again. When the display shows end, remove the weight and confirm the reading is within ±0.02 g. MNM Scales, an authorized A&D dealer, offers in-house calibration with a certificate for $195.00 or NIST calibration with a NIST-traceable certificate for $495.00, nationwide by mail, plus on-site service in the Houston area at $295 plus $2 per mile round trip.
What calibration weight does the FX-3000i use?
The official FZ-i / FX-i manual (section 8.1) specifies a 3000 g factory-setting weight for the FX-3000i. 2000 g, 1000 g and 500 g are also usable on software version 3.10 or later. The calibration weight is not included.
Is the A&D FX-3000i NTEP?
