A dip meter or a grid dip meter can be considered as a kind of frequency meter whose function is to determine the resonant frequency of an LC circuit. For this, the circuits don’t have to ‘radiate’ any waves or frequency across each other. Instead, the procedure is implemented simply by placing the coil of […]

High Voltage Meter Circuit [for Measuring 10kV]
In this article I have explained a simple high voltage meter circuit which can be used for measuring extremely high voltages in the order of many 1000s of volts. The circuit can be used to measure high voltages from CDI units, Automobile spark plugs, high voltage generators, mosquito bat circuits, fence chargers, room ionizer circuits […]
Make this Amplifier Power Meter Circuit
Music Amplifiers have always intrigued us due to their massive amplifying capabilities which completely changes the dimensions of the delivered music outputs. Fundamentally it’s the power of the amplifier that’s always on the scanner and we find folks getting too obsessed by the power rating of their procured amplifier unit. Introduction However many of us […]
RF Signal Meter Circuit
In this article I have explained the circuit details of a couple of very interesting and sensitive RF signal meters, which can be used for measuring the RF strength of the transmitted waves from the RF source without making any physical contacts with the source. Simple RF Signal Meter using IC 741 A RF signal […]
Microamp Meter Circuit
A microamp meter or microammeter is a device that allows the user to measure extremely small current levels, in microamps, which is normally not possible to measure using conventional multimeters. A conventional panel meter or multimeter will not be able to properly measure currents of a few microamps or less. It is required to utilize […]
Capacitive Fluid Meter Circuit for Sealed Tanks
At times it becomes important to determine the amount of water inside a sealed tank, by employing a stationery sensor. A sensible remedy to the issue is to make use of a cylindrical capacitor concept. One plate of the capacitor is created with the liquid surrounding an insulated conductor, where insulation of the conductor works […]
