What do you mean by "I have taken part of current measurement and soldered it"? Did you solder the SB9 bridge again?

Excuse me. I was able to measure 700 μA current only once. However, now measurement is unstable with 2 mA, 3 mA afterwards. What is the cause of this?

Are you using an nrf52832? The #1 on your current consumption graph is most likely advertising (see this tutorial). If you want to lower the current consumption, you can either Google it, check this link, or check out this fantastic tutorial.
