万用表打R×10kΩ档,表笔短接调零后,黑表笔接待判断稳压管负极,红笔接正极,表针偏转稳定后,记下指针所指的“10mA档”值,再按算式V_w=(1-1/10)·V_o算出V_w值,此值即为该稳任管的稳压值。(上式中:V_w为待测稳压管的稳压值,V_o万用表电池电压、Ⅱ为指针的指示值)。对于万用表的电池电压可拆开电池盖板取出电池测,也可把万用表打R×10kΩ档,用另一数字万用表的红表笔接此表的“-”插孔, Multimeter to play R × 10kΩ file, the pen shorted zero, the black pen to judge the regulator negative tube reception, red pen then positive, the needle deflection stability, note the pointer refers to the “10mA file” value, then press the formula V_w = (1-1 / 10) · V_o calculate V_w value, the value is the steady tube regulator value. (In the above formula: V_w is the steady voltage value of the regulator under test, V_o multimeter battery voltage, Ⅱ is the indicator value of the pointer). For the multimeter battery voltage can be removed from the battery cover to remove the battery test, but also the multimeter to play R × 10kΩ file, with another digital multimeter red pen to the table “-” jack,
