Torque wrenches are designed specifically for the automotive, nuclear, and industrial markets, as well as military facilities around the world. This series features a sturdy torsion beam design, reliable long service life, and durability.
The real mistake is within any given range.
3 Circuit: There are two basic methods for measuring the output of torque sensors.
1. Simulation (pure simulation based on non microprocessor)
2. Digital (based on microprocessor and analog input)
Without a thorough explanation of these two systems, the following advantages of having digital circuits are unparalleled in the entire electronics industry.
1. Digital system economy, flexible and compact.
2. In the face of hardware defects, digital systems can improve reliability.
3. Digital systems allow for logical decision-making, performing numerical calculations (infinite unit conversions), and storing the results in memory.
Basically, all digital systems are controlled by computers. The term 'digital display' or 'digital memory' does not necessarily mean that the system has all digital circuits, which is important.

Issues to consider when choosing an electronic torque tester:
Accuracy: There are usually two ways to express accuracy:
A. Full range deviation or FSD
Percentage B. Percentage of displayed value or reading
The following example will demonstrate the difference between the two methods:
Case 1- Suppose you have a 100 foot pound tester (maximum value) and the degree is+/-0.5% of full scale.
At 100 foot pounds+/-0.5% full scale=0.5 foot pounds, this indicates an error in the system's' maximum condition '. However, when using a lower range, this 0.5 foot pound becomes even more important. That is to say, on the same 100 foot pound tester;
0.5 feet=1% accuracy at 10 foot pounds
-0.5 foot pounds=5% accuracy at 1 foot pound
-0.5 foot pounds=50% accuracy
Therefore, what appears to be a full-size reading will actually be converted into substantial readings within the low range of the tester
Case 2- Suppose you have a 100 foot pound tester (maximum value) with an accuracy of+/-0.5% of the indicated value.
At 0.5 foot pounds
0.5% appears at this location. 0.5 foot pounds at 50 foot pounds. -5%.
0.25 foot pounds at 10 foot pounds. -0.5% of 05 foot pounds.
From the above example, it can be seen that as the range decreases, errors related to full-scale values significantly increase, while those related to measured values remain unchanged.
2 Scope: Typically, when manufacturers advertise at full range, their useful range will range from zero to comprehensive advertising. That is to say, the accuracy (full range) from 0-100 foot pounds is+/-0.5%. This is interesting because at zero pounds, the system only reaches within+5 foot pounds. Basically, errors are infinite at zero.
In addition, transducers used to convert mechanical torque into electrical signals may become inaccurate below 10% of full-scale deviation.
For the above reasons, a system with accuracy related to the indicated value should indicate that the useful range is 10% to 100% of the tester range.
Therefore, if the maximum range of the tester is 100 foot pounds, it should not be used in situations where it is less than 10 foot pounds. If accuracy is needed.
CDI believes that in order to be honest with customers, accuracy should always be expressed as a percentage of the indicated value, and the useful range should correspond to the accuracy stated. This will prevent users from having to calculate anything.
Always take these precautions when using any torque wrench to avoid possible injury:
Before using a torque wrench, please read the instruction manual completely.
When using any manual tool, always wear safety glasses or goggles, always pull, do not push, apply torque, and adjust your position to prevent falling. Never use on torque wrenches“Stick "to apply excessive leverage.
Do not use sockets or fasteners with surface wear or cracks. If dirty, mismatched, or worn parts are used, the ratchet mechanism may slip or break. Ensure that the steering rod * is engaged.
The calibration range of all mechanical torque wrenches is 20% to 100% of the full range, therefore, they must not be used below or above these limits. To determine which torque wrench capacity to apply, many factors must be considered. However, as a suggestion, use a torque wrench within 50% of the overall tool capacity. This will extend the tool life, provide convenient use for operators, and increase the accuracy of the "click" type torque wrench.
Be sure to firmly grasp the handle in the middle of the handle
Slowly and evenly approach the final torque
Stop turning the wrench immediately when the target torque is reached
Do not use a torque wrench to loosen fasteners
Should be cleaned and properly stored
Should always be kept at the lowest torque setting
If the wrench falls off, it should be recalibrated. Never exceed its capacity
The torque wrench should be "exercised" at least three times at 100% full range before use
The selected wrench should be calibrated using the same torque unit
Using a stick may result in inaccurate readings and may damage the wrench
If reasonable precautions are taken, the service life of torque wrenches will be longer. After each use, always relax the handle to the lowest setting. Do not attempt to lubricate the internal torque mechanism. Wipe and clean the torque wrench, do not immerse it. The wrench should be sent to a qualified calibration laboratory for recalibration every year or every 5000 cycles.
