This circuitry is usedas the amplifier circuitry that the range is 21X and 20 IX, if the range is higher than 200 IX, it can be settled by paralleling connecting resistance by a header directly. In order to assure linear feature, when it measures a 20 IX tick, the burdenof 2 CR diminishes because of paralleling connecting resistor in 3.9 K Ω, and the error is about ±4%; The stability changes ±endless% annually, but it is effected by temperature, and increasing 1 ℃ JF each time, the value will enlarge 1%.
