A mechanical bathroom scale. Pressure on the internal springs rotates a disc displaying the user's weight in pounds. Electronic digital scales display weight as a number, usually on a liquid crystal display (LCD). They are versatile because they may perform calculations on the measurement and transmit it to other digital devices.
Vernier caliper scales; main at top, vernier at bottom. It reads 3.58 ± 0.02 mm by adding 3.00 mm (left red mark) on the fixed main scale to vernier 0.58 mm (right red mark). The main scale reading is that to the left of the zero on the vernier scale. The vernier reading is found by locating the best aligned lines between the two scales.
Pointers - The scale pointer marks the equal point of the object's mass on the scale and mass on the beam; Zero adjustment knob - This is used to manually adjust the triple beam balance to the 'zero' mark (check to ensure that the pointer is at zero before use). Before using triple beam balance, the scale pointer should be at zero.
Before using a triple beam balance, the scale pointer should be at zero. [6] The zero adjustment knob can be used to adjust the scale pointer. Place the objects on the pan and adjust the riders until the scale pointer is at zero again, and then sum the weights marked (e.g. the 4th notch of 100 gram beam is 400g) to find the weight of the sample.
Digital Weight Indicator also commonly called Weight Indicator [1] is a system of indication or recording of the selector type or one that advances intermittently in which all values are presented digitally, or in numbers. In a digital indicating or recording element, or in digital representation, there are no graduations.
The dieter's problem: this scale can only resolve weight changes of 0.2 lbs, even though the digital display looks as if it could show 0.1. In the science of measurement, the least count of a measuring instrument is the smallest value in the measured quantity that can be resolved on the instrument's scale. [1]
It is usual for a built-in computer to take many weight readings from the transducer over the time that the package is on the weigh bed to ensure an accurate weight reading. Calibration is critical. A lab scale, which usually is in an isolated chamber pressurized with dry nitrogen (pressurized at sea level) can weigh an object within plus or ...
The scale relays this data to a receiver hardwired into the cab, [13] or wirelessly to a handheld unit such as a smart phone, either of which will interpret the data and display axle weight(s) and/or gross vehicle weight. Data may be further transmitted via a wide area network to a company office or corporate headquarters.
