A very common form oflatchcircuit is the simple “start-stop” relay circuit used for motor controls, whereby a pair of momentary-contact pushbutton switches control the operation of an electric motor. In this particular case, I show a low-voltage control circuit and a 3-phase, higher voltag...
Instrument manufacturers also use thermal converters in their RMS voltmeters. A typical circuit is shown inFigure 7. FIGURE 7.Simplified diagram of thermal AC-to-DC converter. This circuit was used in the Hewlett-Packard Model 3403C True RMS Voltmeter. Hewlett-Packard used this basic design in ...
Try spinning the shaft slowly and then faster, comparing voltmeter readings between the two conditions. Step 10: Short-circuit any two of the three-phase line wires and try spinning the alternator. What you should notice is that the alternator shaft becomes more difficult to spin. The heavy ...
3. The analog monitor outputs are the outputs of frequency meter, ammeter, voltmeter and other special instruction, and they cannot be used for feedback control and other control operations. 4. Due to the presence of various types of pulse practice, please refer to specifications for specific ...
In a practical Q-meter, Vr is maintained constant and the electronic voltmeter can be calibrated to indicate the Q-factor directly. If a variable capacitor C is used and the oscillator is set at a given frequency, then C can be adjusted to give resonance. In this way inductance L may be...
