Electronic circuit part of the househ•∑γ✔old electronic scale can not be debugged prope¶™rly.

1. the effect tube of₽∞  the electronic scale selects the pipe with a l↑β←>eakage current of 4-8mA. Indicates that ₹★★¶the watt hour meter PAI has a full current of α≤50~200uA.

2. Resistors R1 and ×☆R2 use fine metal film resistors; potentiome♣↓ters RP1 and RP3 use screw conditi★‍$¥oning multi-loop potentiomeΩ →ters in order to carefully adjusφ≥' t the bridge balance.

3. other components show no special requiremeβ±♥±nts.

The adjustment steps of the​®‍ household electronic s↕'®®cale are as follows: when there is no load,"∑↔← adjust RP1 to make '©σ•the pointer of the meter in the "γ↑•0" position, and then place the object corre"♣≠•sponding to the gauge♥×∑© component of the large measurement (such as g✘γ±‌auge weight) on the electronic sca‍‌le plate to adjust RP3 ♥¥&to make the pointer of the meter↓γ≥ at the terminal of the electronicα¶" scale. The calibration ≤&of the linearity, the use of two-value gauge §×★•weights to stop correction, ifו©  the linearity is not good (especiaαλ↓♦lly in the two-value po↑​sition L to re-select a good >←¥>linear sliding potentiometer RP2. The err‍♦♥®or is too large, the demand is st♦♣'opped by the weights of t≠&≠he standard components, and the scale o♥↑f the instrument PA1 is re calibrated.

Household electronic scale bel¶•¥ongs to a kind of weighing inst₹₽₩rument, which uses Hooke'$ ε✘;s law or the lever bal₩÷ance principle of force↕★♣≤ to measure the quality φ'of objects. Household electronic weighing β>£scale is mainly composed of π↑load-bearing fragments, such as weighing p ∏∑λan, weighing body, force trans‍ ∏fer fragments such as leverage force∑• transfer fragments, sensors and indicators frα  agmentary such as dial, electronic display i‌∞nstrument 3 parts. According ↔®‍to the principle of construction, it can be dδ‌↑ivided into three categories: mechanica✘ ™l scale.

Household electronic scale and Mechatr✔<onic scale

1. Seeing Accuracy: Some weighing sc"≥§πales are not accurate, not accurate i∏π≤∑n weighing, several measurements are dif★™ferent. Such a weight scal±δe should not be purchased and should be weig₩☆hed accurately.

2. Look at the big w∏™→eighing: Different weighing scales have‍$λ different weighing numbers, you should choose a∏™>ccording to the details of your family, if therασ™>e are big thin people will ♦₩© choose to weigh a larger number,₽‌ so as not to exceed the larg♣§e value, resulting in the scale caγ♥n not be used.

3. Investigate how safe t£×he scale is: when stepping on weighing, must hav↑♠₩e very good anti-skid maintenance measures, o≥∑λ≥therwise it is easy to skid on the air bric¥™ ks in the home, causing risk. Theref<✘≈←ore, we should have a good look at♦∑★ the effect of the botto↔♣δΩm slip mat.
