aWhy the voltmeter reading error sometimes feel? 为什么电压表有时读入错误感受? [translate] aThe voltmeter is a high precision voltage meter. After many tests, the accuracy is 1%. If there is a rock, that 电压表是高精密度的电压米。 在许多测试以后,准确性是1%。 如果有岩石,那 [translate] ...
Calculate resistance R of the voltmeter. 2. Open the switch, S, start the timer when the reading on the voltmeter is 40 V, and measure the time required for the capacitor to discharge to a variable voltage, V t = 35 V. Record your data in the table. 3. Repeat step 2 with ...
- A wheeled carrier A has a wire brush B which makes contact with the road surface, and is connected with a voltmeter C, the other end of which is earthed. The carrier is moved over the line of the main, the reading of the volt-meter giving an indication of the extent of the ...

If the voltage reading of the voltmeter does not change, then it does not show the RMS value but the (average) DC value. (Most probably. I don´t know how it is connected, nor do I know it´s specifications) BTW: you say "the varying DC voltage" .. but t...

An instrument is calibrated to avoid errors in the performance and increase the accuracy of the instrument. Here we are calibrating a voltmeter. The main errors that are observed in a voltmeter reading are 1. Mechanical errors due to manufacturing defects. ...
