Proper use of electronic scales
Electronic scales are composed of precision sensing components and microcomputer circuit consisting of, proper use and maintenance of electronic scales accurate to maintain a necessary condition!
Preparation before use
Set of electronic scales on a stable flat table or floor use, not placed in unstable vibration desktop or bench
Avoid placing excessive temperature changes or air flow severe of places, such as direct sunlight or air conditioning vent at
Use a separate power outlet in order to avoid other electrical interference
Adjust the electronic scale adjustment feet, smooth scales and a level bubble residence within the circle center
When the power is turned on, do the articles placed on the pan, heat engine before use15Minutes or more(Precision scales must be longer)
Caution
Rain or rinsing with water is prohibited, if accidentally wet wipe clean with a dry cloth when the machine does not function properly when you want to repair as soon as possible
The impact and the weight of non-beat
Do not placed in hot and humid environment place(Excluding special waterproof corrosion scales)
Do not let cockroaches or small organisms invade the machine to avoid damage
Electronic scales shall wipe if the long-term without a clean machine, desiccant wrapped in plastic bags, have to use batteries should be removed, using a rechargeable battery, should be charged once every three months, in order to ensure the life
Periodic calibration
In order to maintain the accuracy of the scale should be calibrated once a year at least
Correction mode can entrust reputable shop scales, laboratory test or government units in the implementation
Standard weight if factory use, can purchase a suitable inspection itself and do periodic calibration
Use of electronic balance
Electronic balance has a simple structure, convenient and practical, weighing speed and other characteristics, widely used in businesses and laboratories, used to measure body mass
the amount. Currently domestic use electronic balance many kinds, whether domestic or imported; weighing whether large or small weighing; whether high precision or low precision, the basic structure is the same principle . How to properly install, use and maintenance of electronic scales and weighing get the correct result, is one of the effective methods to ensure product quality.
Verification work in the field found that many companies do not balance required to install, use and maintain, resulting in large deviation measurement data exceeds the maximum permissible error verification procedures required. To enable enterprises to staff working balance used to obtain accurate weighing results, extend the useful life of balance, now proper installation, use and maintenance of electronic balance problems that need attention of the following:
1, Chambers of electronic balance environmental requirements
(1) Room should avoid direct sunlight, the best choice nightside room or use the shading approach.
(2) Away from the source, such as railways, roads, vibration and other mechanical vibration, shock measures to be taken can not be avoided.
(3) Should be kept away from heat and high-strength electromagnetic environments.
(4) Working room temperature should be constant, to20'CAround better.
(5) Relative humidity in the room should beforty five%~75%Among the best.
(6) Operating room should be clean, to avoid affecting the air flow.
(7) Operating room should be no corrosive gas impact.
(8) Table should be solid and reliable.
