How to use multimeter test circuit
Measuring transformer: measuring transformer and measuring inductance have many similarities. First, the transformer is composed of a primary winding, a secondary winding and an iron core. There are two kinds of step-up and step-down transformers.The primary winding is mainly connected to the power supply, if you want to measure the primary winding of the transformer TV put two pen multimeter plug the two end on the line, to the ohm value, directly connected to the socket, the resistance should be very small that is good.
The measurement of inductance coil: measurement of inductance coil is mainly measured whether the conduction is Ohm files, just use the probe connected to its two feet, that is the inductance of a wire, measuring its resistance should be very small.
Measure resistance: resistance measurement is mainly measuring the resistance value is accurate, to just use ohm files, probe connected to its two feet, watching the multimeter reading, and whether the actual resistance of the same.
Measurement of capacitance: measurement of capacitance is mainly to measure the charge and discharge is transferred to the ohm value, and then two probes are respectively connected to two feet of it, this figure will be table large slowly, finally become infinite, and then replace the pen, also as before.
