Electronic circuit part of the ★ββ<household electronic scale can not↑Ω be debugged properly.
1. the effect tube of the electronic&₹ scale selects the pipe with ♥"®<a leakage current of 4 ★±-8mA. Indicates that the watt ho'&≠ur meter PAI has a full current of ←✘¥50~200uA.
2. Resistors R1 and R2 use fine metalγ→✔€ film resistors; potentiometers RP1 and→€ RP3 use screw conditio↕× ↔ning multi-loop pote≠↔πntiometers in order to ca®"↑refully adjust the bridge b→alance.
3. other components ♥$$show no special requirements.λ¥
The adjustment steps of the househo®±ld electronic scale are as f$>ollows: when there is no load, ∑×✔ adjust RP1 to make t¥≤σhe pointer of the meter in the &qu€βot;0" position, €βand then place the obj•✘↓§ect corresponding to the gauge compone¶♣↓nt of the large measurement (such as ¥→gauge weight) on the electro↔§nic scale plate to adjust R★♥♥$P3 to make the pointe≤♠₩¥r of the meter at the ter←✘β↕minal of the electronic scale. Thγ≤ e calibration of the linear♠₹↑ity, the use of two-value gauge weight₽♦♠εs to stop correction, if ∑∑₽ the linearity is not good ε→£(especially in the t×★γ£wo-value position L to re-select a go'₽↕od linear sliding potentiometer₹α RP2. The error is too large,>β☆ the demand is stopped by the weights ↓π≠®of the standard componen☆♠ts, and the scale of the inst≈☆↔πrument PA1 is re calibrated.
Household electronic sc∞∏ale belongs to a kind of weighing ins∞€'trument, which uses Hoo♠≤≥"ke's law or the lever balance™✘ principle of force to measure the quality of objects. Household el¶÷ectronic weighing scale →÷<↓is mainly composed of ₽₹β>load-bearing fragments, such ≠₩as weighing pan, weighing body, force ₹₩₩transfer fragments such as ±λleverage force transfer fragments, ↓★sensors and indicator≈α✘€s fragmentary such as dial, elβφectronic display instrument↑$¥© 3 parts. According to the p←✔$rinciple of construction, it can b"σ↕•e divided into three categories: ↑≠mechanical scale.
Household electronic scale €∑and Mechatronic scale
1. Seeing Accuracy: Some weighing scal ≥'&es are not accurate, not accurate λ©α¥in weighing, several measu>γrements are different. Such a we♣σ≈Ωight scale should not be ∏↔purchased and should be weighed accuraφ®δtely.
2. Look at the big weighing: Differen♠®δ→t weighing scales have different we'★ighing numbers, you s★±☆hould choose according to the de×₹γtails of your family,§♠₽ if there are big thi÷♠n people will choose to weigh a larger ≠×£©number, so as not to exceed the ¶ ≈±large value, resulting in the scale ca©↕n not be used.
3. Investigate how safe the s↔♦↔₹cale is: when stepping∏♥ on weighing, must have very good an↓$ti-skid maintenance measures, ot®&±Ωherwise it is easy to♦♥• skid on the air bricks §×>in the home, causing λ♣ risk. Therefore, we shou£Ωλld have a good look at the effect of"♠∞ the bottom slip mat.
