Electronic scale common term science

1. Maximum weighing:

In order to avoid the maximum weighing when attaching the deduction.
2. Minimum weighing:

When the weighing result is less than this load, it will lead to excessive relative error.
3. Resolution:

Weighing / Sensitivity = Resolution.
4. Internal value:

Scale analog signal voltage size.
5. External value:

The internal value is converted to the outside indicated weight.
6. Linearity:

Refers to whether the change in the weighing scale at the minimum scale is a linear change.
7. Error:

The difference between the displayed value and the actual value.
8. Insufficient sampling:

The weight added on the counting scale is lower than the sensitivity.
9. Insufficient single weight:

The unit of counting items is less than 4/5 of the amount of sensitivity.
10. Temperature stability:

Refers to the error caused by the temperature of the scale.
11. Zero drift:

The sensor balances the output voltage as a function of temperature.
12. Zero tracking:

The correction value does not exceed 0.5d in one second, indicating that the stability is maintained below zero for at least 5 seconds.
13. Zero range:

The internal value of the scale during normal operation is ±2%.
14. Weight unit:

Kilograms, grams, Taiwan pounds, etc. 15. Pricing unit: $/10g or $/100g...etc.
16. Net weight:

Refers to the actual weight of the object.
17. Gross weight:

Refers to the object contains the weight of the package.
18. Deduction:

Except for its own weight, the external weight is deducted.
19. Level:

Refers to the instrument at the level of this object.
20. Sensor:

It is the sensor - the instrument that senses the weight.
21. Potential change (creep):

In a constant temperature and humidity environment, if the output voltage is recorded for a certain rated weight and a certain period of time is passed, the output voltage value is recorded, and the comparison error between the two is called.
22. Delay:

Under the same environmental conditions, the sensor is loaded step by step from the zero load to the rated load, and then the load is removed one by one, and the output voltage value of each point is recorded separately, and the load is compared with the same weight value at the time of unloading. error.
23. Temperature compensation:

A method of calculating the degree of influence of temperature.
24. Protection points:

Protect the external force of the sensor from heavy impact.
25. Four-corner weight:

Refers to the weight indication error in each corner of the scale.
26. Liquid crystal display (LCD):

LCD display.
27. Fluorescence display (VFD):

Fluorescent vacuum display.
28. Light-emitting diodes (LEDs):

Light bright Electron electronic DIOPE diode.
29. Button:

An input data device.
30. Voltage (V):

The Ohm's law is formed for the potential difference and current. (V=IR voltage=current*resistance).
31. Current (I):

The number of coulombs flowing per second.
32. Direct current (DC):

Refers to the direction of current is a single direction.
33. AC (AC):

The direction of the current varies positively and negatively with time.
34.INVERTOR:

Converter (DC conversion AC).
35. Charger:

The power supply used to recharge the battery.
36.ADAPTOR:

Transformer converter (AC conversion DC).
37. Power consumption (W):

Refers to the product of the voltage and current used by the instrument.
38. Current consumption:

Refers to the current flowing by the scale (instrument).
39. Analog signal:

The signal size will change its value over time.
40. Digital signal:

Refers to a signal with a high voltage and low voltage state.
41. Amplifier:

Operational amplifier, differential amplifier, IC OP177.
42. A / D converter:

Convert the simulation to a number.
43. Binary:

Binary operation.
44. Decimal:

Decimal operation.
45. Precision:

Refers to the scale of the instrument's measurement range.
46. ​​Accuracy:

Refers to the error between the measured value and the actual value.
