Gauge (Force and Torque) FAQs
What capacity of gauge should I choose?
If you know the capacity of your measurement it is very helpful in selecting a gauge with maximum capacity. At least you should have some close estimate of peak reading. The best capacity to choose is probably between 30-70% of full gauge maximum capacity. You do not want to use too large a capacity to measure small force because it will be less accurate. However, it will be very safe from overloading. On the other hand you use with capacity near the maximum capacity it will be more accurate. However, it will have less room for safety from overloading. It all depends on how predictable your application is. These are the reason there are many capacity ranges to choose from. By the way, the gauge will start to display from a very small force applied, starting from less than 1% of full capacity.
When should I use a test stand?
If you need rather high accuracy and consistent reading then a test stand is very helpful. The mounting gauge on the test stand makes the force perpendicular to the load, which in turn makes the load more accurate. the motorized test stand can be more consistent than the hand wheel test stand with adjustable, same-speed operation. A test stand is needed when you test at high capacity, such as 500-1000N or over. And if you are testing many samples each day then a motorized test stand will be a very good choice.
How long does the battery last?
The battery will degrade over time and its capacity reduced. Generally, you should replace it every few years. The battery could fail or degrade too much, it may drain all the current when charging so much that the gauge may not be able to function.
How fast can the gauge capture the Peak incident?
DFS Model gauge can sample peak and hold the display, in tension or compression, at 4000th of a second. That means it is fast enough to catch peak force when the material breaks suddenly in most situations. The speed of sending the reading data over the USB cable is 10 times or less in a second.
Why I am not getting the same reading each time when I test?
If you are not using a test stand please check whether the load is applied perpendicular, in both the x & y axis. The gauge will read correct and the same reading if the load is applied at a 90-degree angle in both plane, front, and side way. The speed of applying load may also have some effect.
How can I know if the gauge is still reading accurately after months of operation?
Please check the diagnostic page and see the current offset. If it is only a few percent then it is in good condition. Anyhow please send for calibration every few years if possible. If you suspect it is now reading correctly you can hang a known weight to see whether it shows the correct weight.
What is the difference between the Reset and Zero buttons?
In normal operation, you do not need to use Zero Button. Gauge will automatically “Zero” everything it powers up. However, you if attach weight such as grip, clamp, or other fixtures while the gauge is powered on then you would press Zero. Zero works in a similar way as “Tare” on the weight scale. The reset button is the only button required to press after the Peak value display to reset it to zero for the next peak reading.
