Multichannel Current Meter-Recorder
The article describes the development of a multi-channel current meter-recorder, which allows you to measure the current with a maximum value of up to 20 A with an error of no more than 2 %. An electrical block diagram of the device has been developed. An electrical functional diagram has been developed. Experimental studies of the operation of the normalizing amplifier of a multichannel current meter-recorder were carried out using the Micro-Cap 12 package.
