Here are two more photos of where I’ve used the Fluke probe. One is with a 10MΩ FET analog meter for measuring the voltage across a smoke precipitator. The other is with the analog meter ...

So to give a full scale deflection of 10 V for example the meter must have a resistor in series with it of value 10 KΩ, and measuring a voltage thus involves placing what is in effect a 10 KΩ ...

Figure 1 shows an electrical water meter as an example of a battery-operated device. The system uses a MAX32662 microcontroller with just one supply voltage. The input voltage range lies between 1 ...
