Using electronic balance precautions
An electronic balance, the heart of gravity electromagnetic sensor (a total of six one eight pieces of reed general) fine and thin, easily damaged, and the balance of the higher accuracy, the gravity sensing reed is thinner, so in use should pay special attention to be protected, not to balance load weight exceeds the weighing range objects, must not be pressed by hand said disk or the scales fell underground, so as not to damage the balance or the gravity sensor performance change, also weighing an object to temple is not heavier objects) is generally not more than 30 seconds to move and transport should be called disk and tray down.
Two, electronic balance is actually measure the earth to open in said disc on the gravitation namely gravity instrument, but due to the earth's diameter the latitudes, the acceleration of gravity (8m2/s) over 9-9. is not the same, in the use of local the weighing accuracy depends on whether the correction and calibration accuracy of anvil code, right if you find in Guangzhou after school just balance, has a certain error, weighing in the local that does not mean that the balance of any fault please methods according to various types of electronic balance manual introduced by standard measuring Department approved code for anvil can be used for accurate correction of weighing.
Three, correcting mechanism is generally divided into three categories:
Automatic correction: internal standard anvil codes and motor servo mechanism, only need to press a function key can be in the tens of seconds to complete a correction, the general model of 1/10000 grams above average precision electronic days by automatic correction mechanism;
Semi automatic correction: built-in standard anvil code but no servo mechanism, before entering the correction procedures, the need for manual loading and unloading of correcting code;
Manual correction: balance no standard anvil code and servo mechanism need to manually enter the calibration procedure and calibration accuracy in general lower balance using manual correction plus standard anvil code
Four, electronic balance is a highly sensitive to environmental precision electronic measuring instruments, care should be taken when in use, the installation should be no obvious vibration table, do not open in the air conditioning export, if these conditions are not satisfied, should take some improvement measures such as change the using places installed wind ink and also pay attention to adjust the angle screw so that the center the bubble level indicator. One of the reasons why the balance did not adjust well level is also producing weighing error.
The common failures of FA series electronic balance and exclusion
1 fault phenomenon: balance boot cannot pass through, the following fault code
"ECI": CPU damage
"EC2": Keyboard error
"EC3": balance stored data lost
"EC4": sampling module does not start
The reason: fatal error caused by the balance can not work normally
Solution: the balance maintenance
2 fault phenomenon: balance display "L"
Reason: 1) without an open pan; 2) foreign body scales below 3); air ink with a touch together.
Solution: 1) when the scale is placed in the pan seat; 2) gently picked up the scale to check whether there is a foreign body in the scale, take the foreign body; 3) gently rotating the pan or air cover to see if there is a touch of the phenomenon, adjusting the airflow cover position.
3 fault phenomenon: load balance display "H"
Reason: 1) Pan loading objects is overweight, beyond the recent range; 2) had used less than the calibrated anvil code value anvil code or other objects of calibrated scales, leading to open normal range weight overweight.
Solution: 1) weighing only in the range; 2) with Zhi indeed anvil code re calibration.
4 failure phenomenon: the boot display "L", "H" or boot loading display display "H", loaded to display "L"
Reason: the balance beyond the temperature environment allows work.
Solution: the temperature of the environment balance Zhi often work 20 C + 5 C ambient temperature changes per hour of not more than 1 DEG C, and the balance to displace the ambient temperature conditions place.
5 fault phenomenon: the scales display "E1", shows the overflow, the displayed value has been more than 99999999
Reason: the piece rate or percentage weighing, the sample value is too small.
Solution: 1) the piece appears when the "E1", first of all take on the scale of objects, re select the sample number, integer optional 10 samples 2 times, 5 times, 10 times as a sample. Multiple current sample down, reading read the display value can be multiplied by the ratio.
6 failure phenomenon: the display data with normal weighing change once change, appeared suddenly no longer changes
Reason: ever use more than straightening anvil code value object for balance calibration, thus appear larger than a display value after the show no longer increases.
Solution: re calibrated balance.
7 fault phenomenon: press "i/o" key does not appear any display
Reason: 1) no power plug fuse fuse; 2); 2) keyboard error, the key card to death.
Solution: 1) plug; 2) replacing the fuse. Insert the power cord is unplugged, with a small screwdriver and the balance of power socket at the fuse box pry out, replace the fuse; 3) loosen the fixing screw adjusting the position of the key button.
8 fault phenomenon: boot only in the lower left corner of the display screen"." No other display. That balance weighing environment is not stable, the balance can not always get a stable weighing.
Reason: 1) balance glass door not closed well; 2) the eyewinker below or around the pan; 3) air ink an open, resulting in scale and airflow ink scuffing; 4) balance surrounded by strong vibration, air flow; 5) balance weighing and weighing the environmental choice variable range is set properly.
Solution: 1) close the door glass; 2) please gently picked up the scale to observe whether there are foreign bodies, with particular attention to whether the small foreign body; 3) slowly rotating airflow ink or scale observation has no rub impact phenomena; 4)
