Simple circuit detector shortcomings and improvements

1, limited detection range: simple circuit detector can usually only detect some basic parameters, such as circuit on and off, voltage, etc., but can not detect complex parameters, such as current, power, inductance, etc.. For some circuits that require precise measurement, the effect of this detector may be more limited.

2, the precision is not high: due to the use of electronic components with limited precision, simple circuit detector measurement accuracy is also relatively low, may produce a certain degree of error, which is less than ideal for some circuits that require high-precision detection.

3, the introduction of more electronic components to enhance the detection range and measurement accuracy of the detector, so that it can detect more complex parameters, such as current, power, inductance and so on.
