When using the ammeter! Why do you need zero correction? If the measured current exceeds the range of the ammeter, what will happen!

When using the ammeter! Why do you need zero correction? If the measured current exceeds the range of the ammeter, what will happen!

The ammeter pointer will exceed and the ammeter will be damaged

Connect the ammeter into the circuit. If you don't know the range of the current to be measured, you should first use the () range type contact. If the indication is less than () a, then use the () range. It's troublesome

First use 0 ~ 3A range type contact, if the value is less than 0.6A, then use 0 ~ 0.6 range

When measuring the lamp current with an ammeter, what should the ammeter do?
Options: A. in series with all lamps B. in parallel with power c. in series with lamp to be tested D. in parallel with lamp to be tested

c
The resistance of the ammeter is very small, which is equivalent to a wire. If it is connected in parallel, it will cause a short circuit. So it is only connected in series
