No. 1 Weight Set (for all transducers) – TTC3200

The torque calibration weight set TTC3200 belongs to the Snap-on TTC torque tester weight sets range, and Lost in HCM supplies it to workshops and factories across Vietnam. Snap-on lists the country of origin as USA.

Torque calibration weight set TTC3200 overview

Plants that run their own torque tester need a way to confirm it reads true between lab visits. The torque calibration weight set TTC3200 supports that check with physical weights instead of another electronic device. As a result, the reference stays simple and easy to trace.

Each set carries a number in its Snap-on name and matches a range. For example, the TTC3220 set serves transducers from 600 to 2,000 ft-lb. Also, warranty terms differ by set, so check the warranty line on each page.

Specifications at a glance

The table below follows the Snap-on data for TTC3200. In addition, we converted imperial torque values to N·m where Snap-on lists none.

How the torque calibration weight set works

A weight creates force through gravity, and gravity differs slightly from place to place. Therefore, careful labs correct the applied torque for local gravity. In southern Vietnam, near the equator, gravity sits a little below the standard value.

Step loading also shows how the transducer behaves across its range. For instance, a reading may be close at full load but drift at the low end. That is why most procedures check several points, not just one.

Key features of the torque calibration weight set TTC3200

Every set in this family shares the same purpose, from the TTC3200 set to the TTC3220 set. Here are the features that matter most when you plan your tester checks.

• Three range-matched sets. The family includes the TTC3200, TTC3210, and TTC3220 sets. Each one matches a band of transducer ranges, so you buy only the weights your tester needs.
• Low to high capacity. Snap-on lists the TTC3210 set for 200 in-oz to 600 ft-lb. In addition, the TTC3220 set covers 600 to 2,000 ft-lb for the heaviest transducers in the system.
• Set for all transducers. Snap-on lists the TTC3200 set for all transducers in the system. Therefore, most users start with it and add the TTC3210 or TTC3220 set as their ranges grow.
• Part of the TTC system. These sets belong to the Snap-on TTC electronic torque tester and calibrator system. As a result, Snap-on lists them for use with the transducers in that system.
• Physical reference standard. Weights give a simple, physical reference for torque. Because the applied torque comes from mass and distance, the method is easy to explain to auditors.
• Supports in-house checks. With a weight set, a quality team can check its tester between lab visits. So problems show up early, before a faulty tester passes a faulty wrench.

Typical applications

A torque calibration weight set earns its place wherever a plant must confirm its own tester between lab visits. The tasks below are the most common uses we see from buyers.

• Verifying a torque tester. A torque tester checks many wrenches, so its own errors spread fast. Weight sets let you confirm the tester reads true before you trust it with your wrench fleet.
• Checks after tester repair. After a tester is serviced or moved to a new bench, its readings may shift. Therefore, a quick weight check confirms the transducer still matches the applied torque.
• Audit evidence for ISO systems. Auditors often ask how a plant knows its test equipment works. A logged weight check gives clear evidence, because each reading links to a known applied torque.
• High range transducer checks. Large transducers for heavy wrenches need equally heavy reference loads to check them. The TTC3220 set covers 600 to 2,000 ft-lb, so it suits this high range work.
• Training quality technicians. New quality staff learn torque basics faster with physical weights. For instance, they see how force and distance combine to create a known torque on the transducer.
• Comparing two testers. Some plants run more than one tester across sites. Similarly, the same weight set can check each tester, so all sites work to one common reference.

Industries that use the torque calibration weight set TTC3200

Any sector with a large wrench fleet needs to trust the tester that checks it. So weight sets show up in plant labs, hangars, and large workshops. Here is how each industry uses them in practice.

• Automotive and motorcycle assembly. Assembly plants run large wrench fleets that need daily checks. In Vietnam's industrial parks, FDI quality teams use torque testers, and weight sets help them confirm those testers.
• Aviation maintenance. MRO teams must show that every torque tool and tester is fit for use. So hangars at Vietnamese airports use reference checks to support their tool control records.
• Electronics and machinery plants. FDI plants in Bac Ninh and Hai Phong run strict quality systems with tool control. Therefore, their metrology teams use weight sets to check torque testers between lab visits.
• Heavy equipment maintenance. Mining and construction contractors use high-range wrenches on tracks and frames. The TTC3220 set also helps their workshops across Vietnam check the high-range transducers they rely on.
• Automotive service. Large dealer groups and fleet workshops keep their own testers for wrench checks. Meanwhile, a weight set helps them confirm the tester itself before audit season.
• Energy and power plants. Power plants use high-torque tools during planned outages on turbines and pumps. For this reason, plant crews in Vietnam check their test gear before each major outage.

Torque calibration weight set TTC3200 compared with similar brands

Before you buy, it helps to see how the torque calibration weight set TTC3200 compares with other ways to check a tester. However, the key question is fit with your system. Instead of weights alone, also weigh how often you need checks and who performs them.

If your plant runs a Snap-on TTC tester, these weight sets are the simplest way to check it in-house. They match the system and its transducer ranges. Even so, confirm current specs with each maker before you compare options. Specifications change over time, so confirm current data with each maker before you decide.

Choosing the right model

• Start with the list of transducers you own. Then match each one to the set Snap-on lists for its range, from TTC3200 to TTC3220.
• Begin with the TTC3200 set, because Snap-on lists it for all transducers. Later, add the TTC3210 or TTC3220 set when you check higher ranges.
• Check your highest transducer range before you order. For example, a 1,500 ft-lb transducer needs the TTC3220 set, which covers 600 to 2,000 ft-lb.
• Plan floor space and a solid bench for weight checks. Heavy weights need a stable mount, so confirm your fixture before the sets arrive.
• Decide who will run the checks and how often. A written procedure keeps results consistent, even when different staff perform the work.
• Read the warranty line on each product page. Terms differ across the three sets, so confirm them before you place an order.

For other sizes in the same range, compare No. 2 Weight Set (200 in-oz-600 ft-lb) – TTC3210, No. 3 Weight Set (600-2,000 ft-lb) – TTC3220. Also browse the full Snap-on torque tools shop for handles, testers and adapters.

Care, storage and calibration

• Store weights in their case on a low, solid shelf. That way, they cannot fall, and their surfaces stay free of dents that change mass.
• Handle weights with clean, dry gloves and wipe off dust before use. Also keep oil and rust away, because added or lost material changes the mass.
• Have the weights recertified on a set schedule, much as ISO 6789-1:2017 sets 12 months for wrenches. We can arrange recertification through an accredited laboratory.
• Never drop weights or load the arm past the transducer's rated capacity. An overload can damage the transducer, so follow the system manual for each step.
• Pack weights in padded cases when you move them between sites. In addition, keep them dry in Vietnam's humid season to prevent rust on the surfaces.
