% of Reading vs. % of Full Scale Accuracy
The true accuracy of a pressure gauge under operating conditions can be difficult to determine, in part because manufacturers’ specifications are often very confusing. One of the major differences between
Troubleshooting a Power Supply Circuit
Troubleshooting is the application of logical thinking combined with a thorough knowledge of circuit or system operation to identify and correct a malfunction. A systematic approach to troubleshooting consists of three steps:
Zener Diode Voltage Regulators
Zener Diodes can be used to produce a stabilised voltage output with low ripple under varying load current conditions. By passing a small current through the diode from a voltage
What is Contact bounce ?
When a switch is actuated and contacts touch one another under the force of actuation, they are supposed to establish continuity in a single, crisp moment. Unfortunately, though, switches do
Basics of Fail-safe Circuits
Logic circuits, whether comprised of electromechanical relays or solid-state gates, can be built in many different ways to perform the same functions. There is usually no one “correct” way to
Motor Control Circuits
Already we discussed about the basics of permissive and interlock circuits in previous post, also discussed about the basic motor control logic using forward & reverse control. Read : Basics
