6 FAQs about [How to use battery to divide the current meter]
Can a multimeter measure a small current?
Scroll to the bottom to watch the YouTube tutorial Multimeters are great, but they can only handle small currents for short durations and they need to be connected into a circuit which is difficult and dangerous. So instead we can use this, a clamp meter. It can measure much larger currents as well as other functions.
How does a current meter work?
nt flows through the meter. The red probe c nnects to the power source. Some of the current flows through the fuse and feeds the analog-to-digital converter, while the remaining larger current flows throug the shunt and to the load.When the inductive clamp is used, the small induced current is first amplifi
How do I use a clamp meter?
First, if your clamp meter allows you to choose DC or AC current, choose the type of current that’s appropriate for the circuit you wish to measure. Then set the measurement range based on the magnitude of the current you’ll be measuring. If measuring a DC current, don't forget to perform zero-adjustment.
How do I measure a DC current?
If measuring a DC current, don't forget to perform zero-adjustment. Once you’re ready, open the clamp meter’s jaws and clamp them around the wire you wish to measure.
