Isn’t it how it’s supposed to be done?

There are two leads.
One end of each usually plugs into the meter.
The other two ends usually have tips that you connect to two specific points in the electronic circuit.

Do you want to say that you placed the two tips right into the two contacts of the "charger" plug while the meter was set to 4 or 400 mA? No, this is not how it works.

Code:
Voltage:

    +---o  <===== meter tip 1
====|  <
    +---o  <===== meter tip 2


Current:                                           +--------+
                                                   |        |
    +---o  <===== meter tip 1                      |        |
====|  <                      meter tip 2 =====> O)|        |
    +---o  <----- short cable -----------------> O)| 82120A |
                  maybe with alligator clips       |        |
                                                   |        |
                                                   +--------+

Voltage: place the two tips at the two points between which you want to measure the voltage, i.e. parallel to the circuit.

Current: place the two tips in series (!) with the circuit within which you want to measure the current.
